Your 250 top speed?

[Gibbo89]

haha, i only just noticed the sweet tags this thread has.

might go add some more!

[Kyle_Cameron]

Got my GT250R over the ton, just... but i'm sure the speedo's a little dis-honest.

[zealchick]

I can get my vtr 250 to 140 no trouble.... and then i freak a bit :blink:
tried to push it harder an the track a few weeks back but i think the fastest i could get it was about 145 down the back straight, i reckon there is more there but jees the wind force is a little overwhelming. Next week i'll push it a bit harder:yes::yes:

You've been riding your first road bike for two days, and you can already report that?

You're gonna fit in here real well...:yes:

well he is on a sportsbike after all!

[ducatilover]

It's interesting to see the Hyosung results.... They really forgot to configure the speedos didn't they? :innocent:
I'm glad I had dyno readings through all the gears to see how accurate mine was.

[Kyle_Cameron]

Well I have ridden a few before and been playing with dirt bikes for the best part of 12 years.

I just wanted to see how well it went...

[phiretrojan]

i have a cbr250 1989, my top speed i have got is 155 and then i slowed down fast, i was shitting myself :shit: i been looking at a hyosung gt250r aswell, i want to turn my cbr250 into a racebike and look at getting into racing and the hyosung for work and back,

I love my Hyosung, looks good and goes well enough to keep up with traffic fine. Not quite as quick as the CBR's, but cheap on gas. I so far have gotten 400 k's to $24 of 98 octane. Pretty cheap in my books. Plus it'll sit on 120 k's an hour easily. I'm quite chuffed with it lol.

[Brett]

293 kph on a zxr 250c. That was on 91 octane too.



not

[SMOKEU]

i been looking at a hyosung gt250r aswell, i want to turn my cbr250 into a racebike and look at getting into racing and the hyosung for work and back,

Seriously, why would you want to do something like that? The CBR250s are a shitload quicker than the GT250R. If you really want to go racing then race the CBR or get a bucky.

[Laxi]

155 ..... shitting myself ...... look at getting into racing

:brick: :facepalm:

[tigertim20]

:brick: :facepalm:

if he is scared at 150, would you rather he try to learn to go faster on the road where he can lose control, and take YOUR bike out as wel?...

starting racng at the tracks and shit is where alot more people should start early on I reckon. might teach them more about control handling and the physics that affect motorcycles.

:brick: :facepalm:

lol reason i was shitting myself this was on the highway from the hutt to town (which was on a sunday about 6.30am only some traffic, i was shitting myself of crashing and cops lol, so i slowed down not on a racetrack, if i tried this on the racetrack which i'm about to (trying) to find a place to hire out etc, it would be sweet

[phiretrojan]

hummmmmmmm

[gatch]

hummmmmmmm

ussssssssss ?

And chips ?

[Laxi]

it's the time of year when it's hard not to trip over a learner friendly trackday at manfield, and if you decide you want a race bike, then i'd look at 400s, they're cheaper than 250s (even if the proposed law change goes ahead, the good 1s will be off the list still).

[ducatilover]

ussssssssss ?

And chips ?

Or with an iskender/kebab. :woohoo:

[phiretrojan]

ussssssssss ?

And chips ?

but chips aren't cheap :sick:

[Monty69]

The old 250,s (cbr,zxr etc) will waste any of the newer 250s. And the cbrs are still bullet proof after almost 20yrs. Ive owned 2 cbr250s, a nsr and an rgv. Got both cbrs off the clock, so 190kmh ish. Then got it past 200kmh, in the redline 6th gear, drafting behind a mtes vfr400r.:eek: The 2stroke nsr and rgv have rediculous acceleration for a 250 but still wont go much past 200kmh. A mate who owned a hyo gt250r seized the rear cylinder doing 180kmh... Nuff said there:laugh::scooter: If it was me buying another 250 id go for the older 4cylinder bikes. Proper sports bikes.

[phiretrojan]

No wonder why we end up paying more for Registration........... :rolleyes:

Guess what, its going up again! next year

the problem now though, is that after 20 years of being treated like that (and largely by noobs that dont know what chain lube is, or when the proper service intervals are etc etc etc) they are no longer as reliable as they once were.
even the ones in reasonably good nick have deteriorated in other ways. things like brake lines arent designed to be 'for life' items, they should be replaced.
So while they may have the edge in a top speed run over newer 250s, they just don't have the reliability in the long term of ownership.

there is a bit more to it that just having the fastest bike out there.

and before you try rip me out for saying that when I have an R1, I will point out that I had plenty of 'slow' bikes in my time.

Having a bike that 'could' go 200 if it wasnt laying in the shed fucked isnt nearly as good as a bike thats 2 years old, still under warranty and isnt going to need any attention for the next 3-5 years, even though it taps out at 150-160-180 whatever

[brin_vg]

It's interesting seeing people only making mid hundred's out of 250ccs, when I managed to squeeze 124km/h in fourth gear out of my 125 (down a slope) a few months ago.

Perhaps I need to tone down my interpretation of the word 'thrashing'

[avgas]

293 kph on a zxr 250c. That was on 91 octane too.

On a happy note, who gives a fuck?

[White trash]

Timed at the Wairarapa Sprints some years back at 213 average over a flying quater on my RGV250K. Interstingly, it was 6 kays faster than my friends RGV250N (with me riding it), we put it down to the K having a much smaller frontal area although it made it fucking hard to tuck in on.

[ducatilover]

That's very impressive! :drinkup:

[doko]

Had mine up to 155kphr with rpm at about 9x :yes: I think it would get up to 170ish redlining.

nah, that would be about it...new ones get up to 165k. Anyway, why would you ride that fast - it's illegal!

[Blinkwing]

Friend's said the VL250 can't go over 150km/h due to some limiter as he's noticed the needle pulls back every time he approaches 150.

I personally haven't managed to get the bike over 130 and that requires somewhat of a downwards slope ...

160... did not realise :facepalm:

I was in a group ride and told if I fell behind around corners (which I'm still not that keen on hooning around) to catch up on the straights. And I was always going WOT, don't know how much faster she'll go. But definitely got to 160... still doing corners slow though :innocent:

Make sure you don't get caught, (easier said than done) but if you do get busted going 160 ish then your going twice the legal limit so it's probably almost certain that your going to lose your license. but i'm sure you know that anyway, and i have sped too so i'm not keen on being a hypocrite.

but remember at those speeds it is a lot harder to react to certain things that may happen

If you're going to get done for that kind of speed then you might as well not stop if you know you can get away with it.

I'm comfortable going fast on straights... I don't feel unsafe. I told them I was gonna ride at my own pace which is why I was going slow around corners. Surely you don't think 160 on a straight kills you... maybe if you come off... but I don't think there is that high a chance of that happening on a straight when it's you and the road and no other traffic. And your eyes are everywhere as usual checking for any slight movement from animals and road surface...

Urg... no. I'm paranoid when driving fast about getting them so I'm constantly leaning forward to keep as much pressure on the front wheel as possible :shutup:

Even then, they are still possible. I had one at just over 160km whilst relaxed and leaning forwards on my Bros650 in '05 :facepalm: Splat.

When you say tankslapper, are you meaning headshake? or actual tankslapper (broken wrists, steering stops, dented tank etc).

[ducatilover]

Actual tank slapper. Hence the "splat" I put after the sentence. My wrists didn't get broken though, luckily as they left some choice dents in the tank

First time was coming back from St Arnaud down some very long straight road and then again on some straight before spooners.

some amazing big v-twin Yamaha thing in the most delicious blue and it sounded ever so sweet

yes, you would be correct, but I'd probably like it too much and I'd have to speed again just for the :spanking:

My son 142Kmh out of a FXR150 at Manfeild on back straight on the rev limiter
No speedo but did the maths on gera ratios etc

Heres the FXR top speed thread,

http://www.kiwibiker.co.nz/forums/showthread.php/130502-FXR-top-speed

It has all the figures to work out top speed, just find the Primary, gearbox and sprocket sizes to work out your REAL top speed


He had fun on the CBR but it wasnt on the limiter, the FXR was:shit: Bloody hoon :yes:

Transmission:
Clutch: Wet multi-plate type
Transmission: 6-speed constant mesh
Gearshift pattern: 1 down 5 up
Primary reduction ratio: 3.500 (70/20)
Final reduction ratio: 3.428 (48/14)
Gear ratios, Low: 3.000 (33/11)
2nd : 1.857 (26/14)
3nd : 1.368 (26/19)
4th : 1.095 (23/21)
5th : 0.923 (24/26)
Top : 0.800 (20/25)
Drive chain: RK 428HO, 132


13000rpm divided by 3.5 (primary ratio) = 3714rpm (clutch hub rpm)

3714rpm diveded by 0.800(top gear) = 4642rpm (front sprocket rpm)

4642rpm diveded by 3.5 (final drive, 49/14) = 1326rpm (wheel rpm)

1326 x 0.001795 ( wheel circumfrance in Km, 1.795 mtr) = 2.38 kpm (kilometres per minute)

2.38 x 60 = 142.8 kmh


If you work out the wheel circumfrance by the 100/80 17 sizing (aspect ratio over width the wheel diameter ) = 1.855 mtrs. I measured the wheel cicumfrance from the valve down, marked the concrete and measure the length after one turn back to the valve down
Dont know if there would be any tyre swell at those speeds to change the amount?

When we were working out ratios and speeds with my mates drag bike they had 2 height/circumfrace changes from tyre swell. It was doing 145mph tho

This is very true, they are a great fun little thing to ride and thrash the pants off. I love them on a twisty road when I'm in the mood, but, I'd much rather a bit of torque too...for those hills and the traffic.

better late than never...

I've had my 1988 NSR250 off the clock a number of times clock ends at 190 and the needle was some way past that.. I'm guessing about 210km/h.

Had a mate on a gsxr400 with me on one run and i got tapped out before him but he had maybe 2km/h more top end... picking if i dropped a tooth on the rear
I would have had em beat

Very stable at that speed and no carbon was left on the pistons :)

Can't understand why people like 4 stroke 250's..... to slow :) LOL.....

Wait thats all you can buy now... what a shame it is... glad I had my fun when I did.

Ian.


Thats such a good call. 2 stroke twice as fast as 4, 250 4 stroke might as well slash my nut sack off.

my rgv goes past 180, then kph and the redline, i just derestricted my bike last Wednesday now its fucking mental. wheelies (leaning back) 1,2 and clutch 3rd and it will pop up. find me a 4 stroke that will do that. wont, to heavy, to slow. LONG LIFE POWERBAND

You are obviously a sniveling little cock and you can red rep me all you like, i don't give a fuck.

When you are capable of a grown up conversation I might entertain having some debate with you, however until you are able to make an argument worth considering instead of the usual drivel you post, I will continue to take all your posts for what they are, that is mostly regurgitated bullshit in the hope someone will believe what you are saying.

Dear sir.

I would like to thank you for taking the time to voice your concerns regarding my conduct. Because this is an online forum, members of this forum are free to give their opinion on various topics, some of which you may not agree with.

You seem to have launched your own personal vendetta against me, awarding me with abusive rep with alarming regularity and you seem rather obsessed with turning around any statements I make and attempting to use them against me.

Your behaviour is very similar to that of a 10 year old school child, you seem to thrive on bullying others in order to make yourself feel better about your own pathetic existence. It is very immature of you to act in such a manner, and it clearly displays your adolescent demeanor to everyone who views your rather mindless drivel.

If you are genuinely incapable of acting like a mature adult, then be my guest and continue your rather feeble attempts at defaming my reputation. It will only serve to make yourself appear even less respectable to other Kiwibiker members. If, however, you wish to prove that you are indeed a mature citizen as you often pretend you are then I would suggest that you quickly abolish this conflict between us.

If there is anything else I can help you with, or any matters you wish to be further clarified then please do not hesitate to send me a PM.

Yours sincerely,
SMOKEU

Dear sir.

I would like to thank you for taking the time to voice your concerns regarding my conduct. Because this is an online forum, members of this forum are free to give their opinion on various topics, some of which you may not agree with.

You seem to have launched your own personal vendetta against me, awarding me with abusive rep with alarming regularity and you seem rather obsessed with turning around any statements I make and attempting to use them against me.

Your behaviour is very similar to that of a 10 year old school child, you seem to thrive on bullying others in order to make yourself feel better about your own pathetic existence. It is very immature of you to act in such a manner, and it clearly displays your adolescent demeanor to everyone who views your rather mindless drivel.

If you are genuinely incapable of acting like a mature adult, then be my guest and continue your rather feeble attempts at defaming my reputation. It will only serve to make yourself appear even less respectable to other Kiwibiker members. If, however, you wish to prove that you are indeed a mature citizen as you often pretend you are then I would suggest that you quickly abolish this conflict between us.

If there is anything else I can help you with, or any matters you wish to be further clarified then please do not hesitate to send me a PM.

Yours sincerely,
SMOKEU

:rofl:

I am impressed that I have finally read a cohesive and terse post from you. It is well written and reflects well on you as a literate adult. That is far more than I have come to expect from you considering your usual attitude towards other posters on this forum.

Please do not take the red rep I have given you as a personal assault, merely as an indication that I had felt that what you had said was worthy of telling you that were a fucktard in that particular instance.

If you would prefer that I did not express my feelings about your posts with negative reputation I might suggest that you consider what you are saying before expressing it and asking yourself if it is really sensible and relevant.

Suck it up buddy and stop crying.

It is better to be silent and thought a fool than to speak and prove it.

PS:- Might i also suggest a reread through your post might be in order. My personal opinion is that your use of substances may be making you paranoid.

[Spyke]

I tell ya what DREAMER.. Come into Auckland City tonight with said ZXR250 and we wil go for a ride on the southern motorway at 2am I will stick at a true 195kph and if you pass me I will give you 2 $100 notes ! !

If you don't pass me.. YOU LEAVE KB FOR EVER !

Crazy Steve.

Only cause you know it will take the whole motorway to catch the difference in accelleration :innocent:

[gatch]

Thats such a good call. 2 stroke twice as fast as 4, 250 4 stroke might as well slash my nut sack off.

my rgv goes past 180, then kph and the redline, i just derestricted my bike last Wednesday now its fucking mental. wheelies (leaning back) 1,2 and clutch 3rd and it will pop up. find me a 4 stroke that will do that. wont, to heavy, to slow. LONG LIFE POWERBAND

Can you ride it around a corner though ?

Noone buys a 250 for it's straight line performance..

Unless of course it's a proper rs250.. Those things are fuckin inSANE. I'd sell my mother for one...

Really.

[Brett]

293 kph on a zxr 250c. That was on 91 octane too.



not

LOL...someone red-repped me for this post. Did I say 293kph?? I mean to say 393kph.
(I pity you for taking the above seriously.)

[Chancebmx25]

The rgv which is fully unrestricted gets to 180km on speedo then just ticks over and taps against itself going back ans fourth. It wheelies in first n second and yes like the other dude said u can clutch em in 3rd.

[jaffaonajappa]

Who gives a Flying Fuck? I mean really.

My 150 does better mileage and is easier in traffic.

My old 1000 or 1100 will blitz any 250. (unless your talking RS or TZ on a track of course lol).

So does my 600 if I need it to and it cost me less than a decent RGV would :yes: I've never seen a two stroke 250 lift the wheel without the clutch, have you got a vid?

[Brett]

RS250 and RGV 250 both will lift in first gear with assisted weight transfer, no clutch up. Second gear??...I am doubting that.

[ducatilover]

RS250 and RGV 250 both will lift in first gear with assisted weight transfer, no clutch up. Second gear??...I am doubting that.

I've never tried with weight transfer on one of them.....Sounds a bit like a mate of mine who had a CBR400RR that would "lift the front in third on the power".
Thing was raped and couldn't outrun my CB400 :facepalm:

[Chancebmx25]

RS250 and RGV 250 both will lift in first gear with assisted weight transfer, no clutch up. Second gear??...I am doubting that.

Your givn it shit in second make it lift. I have different sprocket sizes. I gt a renthal kit for rgv from the uk. I assume it contributes majorly to my ratios. So yer, i doubt a stock rgv would. It needs to be worked.

[Chancebmx25]

So does my 600 if I need it to and it cost me less than a decent RGV would :yes: I've never seen a two stroke 250 lift the wheel without the clutch, have you got a vid?

I could get one.like i said to the other guy my rgv has got different sized sprockets, i got more acceleration over top speed, the renthal kit i got downsizes from 14 to 13 and 43 to 41. I assume this contributes. But like i said it hits 180 and taps against itself, a digital speedo would be the one. To get a solid reading.

[ducatilover]

I'm keen to see a vid of it, i'd be hella impressed if it's doing it on the power in second :yes: Would be a neat video for sure.

Those sprocket sizes equate to a small difference, 6kmh in top gear at 12000rpm.

It's bloody quick and lifts the front wheel in second no sweat, he's doing it all the time but as has been said, it's geared slightly down and the front suspension is also a bit bouncy which helps heaps. These are fast bikes and will keep with a 600 to 100kph.

Vids or it didn't happen. I haven't ridden one that'll keep up with my fat old 600 in a straight line.

[racefactory]

I'll put a fair bit of money down I can launch Chance's RGV250 to 100 as fast or faster than your 600. A ZZR600 is not the fastest and an RGV250 is 120kg...No problems.

[ducatilover]

I'll put a fair bit of money down I can Chance's RGV250 to 100 as fast as your 600. That is a slow 600. No problems...

:yes: Cool, I'm not worried if it does. Would be nice to see one that's finally as fast as I keep getting told. The best ones I have ridden would take most 400s I have ridden, which certainly isn't fast. Or wheelie tastic. The 600 will be doing mid 3s to 100 and mid 11s down the strip, the RGV250J manage a high 12 in perfect conditions. Would be interested to see a decent test of how quick a top notch one is

[racefactory]

Above 100, no comparison. But 120kg bike is not to be messed with in a launch!

[ducatilover]

Above 100, no comparison. But 120kg bike is not to be messed with in a launch!

There's no doubt about that, I'd be quite interested to see an RGV launched properly. I only have 90 odd horse at the wheel, not much by now days standards, but, it doesn't have gearing like the newer 600s either and has more power down low. So I'll keep mine, because it's a great bike to ride every day and long distance :love:

Truth be told I've been tempted to find myself a nice NSR as a toy.

http://youtu.be/watch?v=aRrQ8bkfk9c&feature=related A slow RGV....:facepalm: Or is that normal?

Come meet up with us if your in aucklandBesides that meh who cares whats faster lets just go nuts and get some serious downs. Id prefer my rgv over ur zzr just cos thea awesome to rebuild and tinker with knowing that the will be mint when ur finished. Plus its light and agile. U can throw it down around twisties like theres no tommorow.

My thoughts exactly, I'd rather ride my ZZR in town or long distance, but, I'd take the RGV any day when it comes to having a blast on my favourite roads :yes: Really makes my want to get a little two stroke, massive fun on my local thrash roads.

I'll take that bet. Having owned 4 RGV's they're certainly fast little bikes, but a semi decent ZZR600 is actually a deceptively fast machine. Not to mention will require no gear changes during the 0-100 sprint.

Check the tested times from the era, you'll probably find an RGV goes 0-100 in around 4.5 seconds, and a ZZR sub 4.

Still 4.5 to 4 when a zzr is twice as big. + more.

:yes::yes::yes: Damn right dude.

I'll be keen to line up an RGV though, just sorted my flatspot in the midrange. Expecting to have 90-95hp at the wheel, should haul the massive 195kg along well with my 50kg on it :scooter:

good stuff... my 69kg's on my 59-60HP rgv is perfect lol.. just waiting for a day off work to throw my new gpra10 front and gpr200 rear tyres on. lol

[GrayWolf]

Well one things for sure,
the bikes may be somewhat faster than the 250's we learnt on in the 70's. Well the super sport 250's are but the general run of the mill 250's perform about the same.
However oh yes, reading these posts about how fast? The average learner hasnt changed at all....
Now let me tell you about my mates Triumph trident running on 2 cyl, that out accelerated a Z1..........................:corn:

[Dodgy_Matt]

Man... back when I had my old 91 TZR 250 V-twin was restricted to 189kmh then would cut out at 190... So i would just hold it at 185...

Note I was 100kgs and it was back in 97.. lol


And last year I had to get my full license so I got an old 94 ZXR250 and I there was no way i would do over 180... but thats cos it was a pos and didnt stop to well.

And I am now 115kgs.... hahahahaaha

[Custom-R]

I'll put a fair bit of money down I can launch Chance's RGV250 to 100 as fast or faster than your 600. A ZZR600 is not the fastest and an RGV250 is 120kg...No problems. Wow 120kg's where did the other 30 odd go? He's gone from a gearing ratio of 3.07 up too 3.15.Thats hardly going to send the front wheel skyward in second gear...Iv'e had both the rgv and nsr sp models derestricted and in good tune and they couldn't do it.
Top speed from memory was around 200 for the rgv and a max of 190 on the nsr...Get your shifting bang on and you'd prolly have that zzr600 tho'

[ducatilover]

Get your shifting bang on and you'd prolly have that zzr600 tho'
:woohoo: I'm up for it.

[Custom-R]

:woohoo: I'm up for it. Yeah only problem I can forsee is old mates wheel will be up in the air after he snatches second that his speedo wont be much to go by...ummm maybe a 150m drag race instead?:ride:

There is a "heavily" moded Ninja 250 for sale on KB forums that claims it can do 190 kph, so you boys and girls better be afraid. :laugh:

I got my Spada to 150 yesterday on a private closed road : )

Will be taking it out tonight for another test run however I don't think the little thing as much left in it!

[5150]

My 08 DR650 saw 180 kph before I sold it. That was with knoblys on and when the arse end started bucking, I shat my self and backed right off. :pinch::shit:

To be fair, it had the airbox mod, FMF Q4 pipe with spark arestor out and stage 2 Dynojet kit.

In standard form they tend to taper off just after 12,000rpm. Get some balanced headers on the bitch and jet it :yes:

[MikeD400]

I only JUST nipped 180 on my Hornet fully stock as far as i know lol.

[Brayden]

Haha I have no mechanical knowledge is this somethin to do with the carbs?

Yeah if I'm cruising at like 130ish in 5th it seems to almost lose power or limit power at around 11-12 ish revs, itll make it up to 140 but as I switch into 6th it just loses power and wont go any faster.

I think it may be due to the wind or something, but its still got another 3000 rpm till ride line to go at 140, I think the wind might be holding me back

The exhaust has a "balance box" just under the rear cylinder. When that is removed and you have made a set of sexy equal length headers it pulls better up top, I'd say the carbon build up and funny air-flow plates in the balance box cause turbulence and inhibit gas flow. It was the best thing I did to mine, made it much nicer to ride and sounded way better than just a silly loud exhaust can.

Mine ended up doing just under 160 before you'd change in to 6th and it would keep going (not very fast...but it's a 250). I had a higher profile rear tyre on it though to fuck with the gearing.

When I got mine it would pull 155 in to a head wind.

Is that on the track as well? was looking for a 250 ninja for road racing but can't seem to find one with enough mods, also i think the guy is running the wrong powerband and his flux capacitor is running a little lean.

142kph at Hampton race track last weekend on the straight, reckon shes got more in here though

[steelphoenix]

I've had two Honda CBR250RRs (MC22L, 1990). Both of them have hit the end of the speedo at 190kph and still been accelerating.

Don't tell the popo... :shifty:

[Nastrond]

Just over 160 on my 09 Ninja. Think I may have got a bit more but the bike felt a little unstable at that speed.

[gatch]

Had my ol spada up to an indicated 170kph or so. "Chasing" an r1 and a ss900.

In reality probably not much over 150. That run was the beginning of the end for that bike.

[P3PS]

clocked at 150-155 range on my Zeal on the freeway, on 5th gear, the 6th does not really do that much (its more of a cruise control mode). Some says it would do an easy 180, i have always doubted that.

haha yea I doubt it too. Depends on your weight and aerodynamics eh. My fully faired CBR250R with exhaust and tune, and its engine in good condition really didnt make it much past 160.. maybe 170 with a tail wind or down hill and really head down/elbows and knees tucked in :D I weigh 87kg.

When I ran it without fairings that would be cut down top speed heaps, prob to the 150 mark and you wouldn't get much more out of it no matter how much you tucked in.

I'd say 150-155 is about what your going to get. you could always fit nitrous.. http://www.ebay.com/itm/NOS-05029-Sneeky-Pete-Hidden-DRY-Carbureted-Nitrous-Kit-/400260205914?pt=Motors_Car_Truck_Parts_Accessories&vxp=mtr&hash=item5d315e0d5a

CBR250's get clocked at a bit over 190km/h real speed, some have bumped 200.

So, about the same as a ZX10 in first gear.

I got 155kph out my near brand new xl250 1996 model maybe its the torque more than the hp

Look the worlds fasted indian no am not meaning somone had a curry

or vincent 1000cc more to speed than multi engine or being latest and greatest ?

Mind you the speedo might been way out , i got such blasting by the wind i whouldint call it it fun

What is it with small bikes you just want see what they can do much more fun than big bikes

Even if its my old xl 100 k2 its 80kph by the way dont laugh to much

I wonder what modern 125 cc or 150 say the new cbr 250 r will do much more intresting than going

fast going fast with less that takes planing and much better than hitting it with horse power

haha, on paper the specs say it should hit 180-200. So no doubt. I couldn't get 3 to do that without a loong straight. They seemed to drop off at 160 if I remember. It has been years now. Anyway - from a Zeal I wouldn't expect much is the point

But, some get horrid power delivery problems, I rode on that bogged between 10-17,000rpm...now that was shit.

[actungbaby]

Well okay thats cool but didnt find it much of a challenge on my cb750 intergra did 160 kph didnt seem to take much effort full fairing
keep in out the breeze but didnt make me go wow either all your doing is twisting a hand grip big deal hehe

its the stoping thats intresting at that speed




You think that people with litre-bikes DONT like to go and see what they do?, and you DONT think that would be fun?...:killingme:killingme:killingme

[nzspokes]

Not bad for a 25 year old single.

Factory spec is 165 kph. So over the years its lost 25ks. 1 per year. Our the tester was a 15kg kid on a really long downhill. Not a 40 something thats over a 100kg. :(

True.. yea they are ok for a 250.. Didn't expect much from them from 10-17 anyway.. 17-18 was pretty much where it gave it some effort. Think to wheelie it I would rev slip the clutch and let the revs hit 15-16 eh.. They were very peaky from mem. again been many years since I owned and road em.

Anyway still going with don't expect to be doing 180+ easily on the little zeal, and I don't find the cbr250rs that amazing over 160.. you have to wait around, im sure they can do it. - 2 stroke 250 is a bit more amusing.

A well cared for and properly tuned one in standard form has a fairly flat power delivery with a small step in "power" at around 10,000rpm. Poorly tuned/maintained ones are peaky.
250 four strokes are all gutless anyway....

Two stroke is definitely more amusing. :headbang:

I wouldn't think so. That thing is going to be pushing against a huge amount of air. It works really well on a CB750 in terms of keeping the air off the rider but it's not designed with top speed in mind.

[roadkillnz]

My 2t 250 road bike (rmx-250) has no trouble accelerating above 100, though it's geared fairly short. If I didn't care so much about my licence etc, 5th gear would end around 150 at a guess.
It's running a 15 tooth on the front, instead of the factory 13 tooth. But that's because it was sitting too much on the power at 100 in 5th... not the most relaxing thing to ride when it's so peaky at 100.

[Armi]

Not a 250 but fits the L plate. My FXR150 has seen 151 indicated. It does 132 on the gps at 140 indicated.

haha.. meh.. I'd have to say i've ridden a neglected one and it just didnt have any power at all. It is the well maintained ones that make any power at all, which really comes in at high rpm. 15,000rpm plus. I can't remember ever having to stop brewing my cup of tea on the tank around 10,000. One can even google some power curve charts to see :D

Get out on the bike and ride, enough of this internet shit. CBR250Rs are a fun enough bike, but if you want 180+ get a 2 stroker or a big bore. Thats what im getting at

Would a big fairing like that be that much more efficient than a rider crouched over the tank? It's got a fair bit of extra air to move.

[nzspokes]

I think you would be surprised. Bikes are horribly inefficient at cutting through the air, which is why gutless crap like a Lamborghini has a better top speed even though it weights 2 ton and makes fuck all horsepower.

Thats my thoughts to. But he says it weighs 25kg so im going to give it a miss and find something lighter.

[imdying]

I don't know, but I would hazard a guess and say yes.

Compared to car, a bike is basically an aerodynamic brick. 300hp cars seem to get to 300km/hr just fine, even though they weigh over a thousand kilos. An average road bike weighs maybe 200kg and needs around 150hp to get to 300km/hr.

Leaning forward on the tank doesn't negate the front being all flat/bumpy with horrible forks/radiators and other un-aerodynamic shite. Even with all the flash fluid dynamic models in the world, they still don't know a lot, other than pointy objects have a lower cd.


All those figures are obviously just ball park shite to get a point across... anybody looking deeply into them and arguing them will either be ignored as a git, or scathingly ripped into in a manner not seen on KB for a wee while, at my discretion.

[imdying]

Thats my thoughts to. But he says it weighs 25kg so im going to give it a miss and find something lighter.Bloody 'ell, 25kg :eek:

Yeah, the concept itself is fine, but yeah look for something lighter. Basically all you want is a top fairing from any thin and pointy. Assuming you don't go so thin as to have nothing to hide behind, then thinner is better. Have a good look at recent 125 and 250 GP bikes for pointers. They also go to the trouble of cleaning up the air coming off the bike too, FWIW.

At $10 this might be worth a try if you can get it to Auckland somehow.

[imdying]

That'd be a good start... tallish wide-ish screen to push the air over you whilst you're tucked.

Anyone remember the CBR600RR double bubble screen test they did in PB? Something crazy like a 19% improvement in the 140-150mph time just by changing to a double bubble. That's cheap HP right there.

At <100mph you're looking at picking up percentage points, not wholes, but every little bit counts right.

[nzspokes]

Mount it to the forks and have it turn with the bars? Cant see how else it would work?

[imdying]

Haven't been in that position before, might pay to ask an old codger :laugh:

TBH though, on a CBX250, I'd be looking for things to increase comfort... you're not going to cut your trip time down appreciably. Having said that, a GP125 isn't a slouch... but I've taken craps that weigh more than those.

Comfort is fine but speed from 100 to 130 is an issue. Mainly for overtaking. Another 10% would make a huge difference. And at that speed a fairing could well help. I have a small Givi screen on that will help so maybe a bigger one.

Dont really think that CBR one would work out in the long run.

That was on my old Spada, someone has fucked with the mounts though (had CBR mounts.) good to see my paint has lasted. They've done a good job of ruining the headlight mount I made...no idea what they've done to it.
The front guard he's selling was on it too, it was for a Bros650. Some dick has painted it, way to fuck a $300 Tyga guard...

Idiots.

The pic without me had a better mount set up.
My lights ran a separate mount to the fairing so I could remove it if I wanted, they could be (and were) adjusted. The lights were aftermarket and shit. Getting Honda ones would be far better and still cheap.
The fairing worked well, made it much nicer on windy days.
A CBR250R MC19 fairing may look nicer as it's not as wide.
Or something retro? I had a Givi screen but, sold it with the CB400, they work okay too.

I may have found one of these. Its a later bike but would be an easy swap.

[Grantman_]

The CBR250RR MC22 can motor up to 180 without drama and continues to claw speed. But the twisties is where it's at with a bike like this. You can be left behind by bigger bikes, and outgrow the power, on the straights, but in heavy twisties the bike comes into its own like nothing else. Wave the big bikes goodby and enjoy the fun.

In fact, the highest speed I recorded on it was 214kph (GPS again, and yes I do have the recorded 'track' to prove it) when I was running a highly modified set-up, but it wasn't economical for the street so I have since gone back to almost factory settings.

A gps units accuracy can be quite a variable thing. Older units were horrible compared to modern SirfIII units etc.
