My Comet250 not fast enough!

[twistadias]

Hi guys,

I am going in for my restricted license next week. Some of my friends told me that they make you go on the motorway. To tell you the truth I ahve never been on the motorway on my bike because i can't go above 70km due to learners. So I gather my balls together and set out on a small drive from hillsborough to penrose. The problem is that as soon as I go above 70 and leave the acceleration, the bike decelerates really fast . Usually on normal speeds like 30-60kmph the bike continues normally as it shud. Know whatIm sayin?

I am so disappointed. I was lookin forward to get my restricted and go ridin thoroughout the north island.Is there somethin wrong with the bike??I just did the wof 2 weeks back and only ride on sat/sunday.

thanks

[Mr. Peanut]

Are you sure you're not talking about wind resistance? Can your bike actually hit 100?
Over 60-70km/h wind resistance slows you down pretty quick, Yknow the wooshey stuff? :lol:

[skelstar]

You dont do 100km/h when youre sitting your restricted licence :weird:...also youre riding a v-twin, they decelerate very quickly off throttle.

[Wasp]

my bandit willl drop from 100 to 80 in a few seconds if i drop the throttle

[Mokoro]

as mentioned above, you won't be asked to go 100km. I didn't think they'd ask you to go on the motorway either..

Its almost hard to take this thread seriously..... seriously, if you can't keep at 100km or understand whats required to keep that speed, (although its not exactly a requirement for the test) i wouldn't think you'd have enough confidence to do the test. (ie you aren't experienced at all)

[Ixion]

I either do not understand your question, or do not understand why you think you have a problem.

All machines will decelerate on the overrun, a Vtwin or single more markedly so.

This is of course used as part of the riding technique for such models. Obviously the deceleration will be more marked at 100kph than at 30kph.

You should be using this as part of your set up for corners, setting up and chopping down a gear or two to set your speed.

How many kilometres have you actually ridden? Have you done any training courses, suchas the RRRS course?

I also share the concern expressed as to whether you are ready to advance. If you plan to "go ridin thoroughout the north island" I think you will require a much higher level of proficiency than appears to be the case from your post. Though, in fairness, I am unsure if English is your first language so it may be that I and others have misinterpreted.

[limbimtimwim]

. The problem is that as soon as I go above 70 and leave the acceleration, the bike decelerates really fast . Usually on normal speeds like 30-60kmph the bike continues normally as it shud. Know whatIm sayin?They 250 vtwins do that. I remember thinking it felt violent.. Hahhaha.. It's not on the grand scale of things.
I am so disappointed. I was lookin forward to get my restricted and go ridin thoroughout the north island.Is there somethin wrong with the bike??I just did the wof 2 weeks back and only ride on sat/sunday.Nah, it's probably fine. The hyobag 250 is a weak little wuss of a thing. But I can ASSURE YOU that riding around the whole country on it is quite possible. Indeed, I encourage you to do it. I did it on my Honda VTR250 it was awesome. Made me fall in love with the South Island. Skelstar here did it on his 250 Comet, and I am sure he enjoyed himself very much.

[McJim]

Yep - you are supposed to hold the throttle open to keep going - it's not like a manual car - I've managed to get the VTR over 130kph in 4th gear so I imagine the Hyosung should do 100 easily - speak to WarlockNZ and Swantiger - both users of the Korean 250's - if you're bothered by engine braking get a 2 stroke - like Mr Peanut's - be prepared for the fact that it will have twice the power though.

Excuse me - must remove tongue from cheek - 2 stroke inappropriate as pointed out by Ixion below - very fast by comparison - do not attempt to ride one until 4 stroke fully mastered.

[Ixion]

I have followed Mr Swan Tiger on his Comet at over 120kph and he was not on the tank. I have no doubt they will easily maintain the legal limit and more.

A two stroke would be most inappropriate in this case I think.

[BarBender]

I'll be happy to help you out if youve got any probs - PM if you want to catch up this weekend and I'll go for a ride with you for an hour or so.
Sounds like youre in my part of town.

[LilSel]

I am going in for my restricted license next week.



OOOoOOOooo Tuesday?.. Carbine Rd?

.

thanks


Please dont tell me that you are riding in top gear at 60kph with the revs in the bottom third of the gauge?

[SARGE]

its all in the clutch man..clutch in slowly.. back off the throttle and feather the clutch out as you need to...you effectively 'coast'

vtwins and singles have engine braking to spare..

[stunz]

you also decelerate really fast at 70ks if you are still in first gear. :yes:

good luck for your restricted test

[SwanTiger]

Indeed, the GT 250 and the GT 250R are capable of 150 kmp/h plus however they do drop speed extremely fast when you completely throttle off.

It kind of sounds like you are trying to use the throttle like you would the accelerator in a car. You can't really coaster along as easily on a bike as you can in a car for many different reasons - high school physics will explain that one.

[skelstar]

Most I ever got out of my Comet250GT was 140km/h. Maybe a smidge more but not much. Maybe gearing a little different on the 'R'...at least the wind-resist will be.

[SwanTiger]

Doesn't a naked bike lose 15 or 20 kmp/h to wind resistance?

My Girlfriends GV 250 will do 120 kmp/h with me on it however I've read on here that one guy gets 138 kmp/h out of it.

I imagine the gearing is a bit different, but still the GT 250 comet should be able to pull 100 kmp/h no problem. It takes a lot of work to get my girlfriends bike to 110 kmp/h and I imagine the GT 250's are the same being naked.

Did you ever hit redline in top gear skelstar? my GF's bike only pulls up to 9,000 rpm (120 kmp/h) but has a 11,500 rpm red line.

[skelstar]

At 140km/h (closed roads of course) it was 10,500rpm I think. I imagine you could cruise the Sth Isl at 120km/h no probs at all. Apparently.

[twistadias]

I guess you guys are right. Maybe its just me who needs more practice. I thought it would trail along smoothly as a car does on speeds like that.

Guess i should postpone the test

[McJim]

Don't postpone the test on such a small detail dude.

If you have trouble getting round corners - postpone your test.
If you have trouble accelerating away from a junction - postpone your test
If you don't know when to indicate - postone your test
If you have difficulty bringing the bike to a safe stop - postpone your test

But for something as minor as not knowing the throttle on a bike is a completely different animal to the accelerator on a car - make mental note and adjust - Best of luck with your test.

[Crisis management]

Guess i should postpone the test

If you want a semi-literate opinion of your riding, I am in Hillsborough and would happily follow you around the block a couple of times and tell you what I think.
Sounds like you would be OK and just need a bit more confidence....if I can help give me a PM

[skelstar]

Yeah mate, dont give up. I got the feeling that when I did my R test it would be hard to fail. More about road code than anything else.

Wow! About 130 is the best I've been able to do on my VTR. I guess 10kg (or 100N) makes all the difference...

[Morcs]

Or just buy my scooter...

Pulls 120 all day long :scooter:

[McJim]

Wow! About 130 is the best I've been able to do on my VTR. I guess 10kg (or 100N) makes all the difference...
Nah - it's the mass not the weight that makes the acceleration less - and with greater mass that would increase your inertia for a given velocity which means your terminal velocity would be greater....blah blah blah..

Actually I've fitted a little Givi Airstar half arsed fairing to the front of my bike so when I tuck my head down the bike goes faster.

[Ixion]

Not entirely . Greater mass (weight, more or less) will increase rolling resistance, and inertia. And usually, heavier rider = bigger rider, more air resistance.

By experience, rider weight does make a difference on small bikes.

But remember, on a naked bike you will only get top speed flat on the tank. (real pros used to climb inside) And on a small bike the last 10 or 20 kph may take a LONG straight to wind up to.

[TerminalAddict]

And on a small bike the last 10 or 20 kph may take a LONG straight to wind up to.

:D .. took me about 3 kms of straight road to get my xv250 from 130 to 140 :) .. and it would only do it if I had been riding for at least hour, and the engine was nice and warm.

Even now, on the 919, there is a marked difference between a cold engine, and a warm one.

[Searchin']

lol.

(Apparantly my message has to be 10 characters.)

[WarlockNZ]

Ah the mighty hyo hyo, just for the record. umm hello Mr Plod :) .. i've had the GTR up to 150 and she was pulling about 10k, with a redline at 10 and a half, i see no reason why you would be lacking power.

I ride to work everyday at 100 (legal limit :innocent: ) and she sits on 7500 Rpm, Engine breaking is pretty quick on the GTR so you will need to be aware of that.

Of course that being said, it may be that it was babied when it was run in, i have heard some stories that a poor run in can cause a lack of power, but i'm sure to be corrected if i'm wrong.

In short the Hyobag is plenty quick, with more than enough grunt for a newbie.:done:

[toymachine]

same with my gn.... have to be riding for quite a while before shell happily sit at 100k or higher...before then, im stuck at around 80-90k cos otherwise she sounds like her guts are about to drop.

[EroSamnin]

I have a GT250 and can sit upright at 120 doing 8000rpm or so. I did make a crappy shield at work out of a reject dome we had and that makes it easier to sit upright. Starts to get a bit interesting at 135 but still plenty of rpms left to go faster. Just don't want to get too unstable and go flying off the road into one of the lakes. Man the rotorua lakes are the most fun ever to ride around.

[twistadias]

Maybe a dumb question but what gear do you guys ride at 60kmph:scooter:

[SwanTiger]

Maybe a dumb question but what gear do you guys ride at 60kmph:scooter:
5th gear if I am cruising through a 50 or 60 kph zone, the bike has a nice portion of torque to accomodate this from down low.

Suppose it depends on what you are doing. I'm curious to know why you asked that though.

[McJim]

Maybe a dumb question but what gear do you guys ride at 60kmph:scooter:

Dunno what the gearing is like on the Comet but on the VTR250 I sit in 3rd at 60 doing 6000rpm.

[Maverick]

Dunno what the gearing is like on the Comet but on the VTR250 I sit in 3rd at 60 doing 6000rpm.

The Bandit will do 70kph in 2nd gear, but is happier in 3rd :P

[McJim]

The Bandit will do 70kph in 2nd gear, but is happier in 3rd :P

He's not asking what it CAN do but what you DO do!

The VTR redlines at 11,500 (although I had it up to 13,000 chasing the Dover last Thursday - it was still pulling too!) and will therefore do 115kph in 3rd.

I don't care what you say Mav - I still prefer V-Twins! And I'm with Ausin Powers on the subject of Japanese twins too!

[Transalper]

Maybe a dumb question but what gear do you guys ride at 60kmph:scooter:No, it's an interesting question, i'll have to take more notice next time i'm out.
Usually I think i'd say 4th or 5th on a 6 speed box.
I'd select a gear that doesn't make it rev it's guts out but one that still gives some go when you twist the throttle... if you follow what i meen.

[WarlockNZ]

*cough* :P

shhhhhh !!! .. hee hee

[gijoe1313]

Crikey! Any usable info from this gabble? Not to worry, McJim got it sussed - its all in the confidence and making sure you follow the road code while handling the bike well!

As for you WarlockNZ, I know exactly where you coming from...100 reasons of it :shifty:

As for McJim, yes I was suprised at how people were trying to benchmark their rides on the Kaiaua blat! Lying on the tank ... sounds like serious business there!

[McJim]

shhhhhh !!! .. hee hee

Yeah - Hyos can't be that slow - I keep hearing about people losing licences on 'em.

twistadias - did you take up Crisis Management on his kind offer?

Rule number 1 of being a newbie - never turn down a helping hand.

[vtec]

Interesting.

I read a fair bit of what goes on in Club 250, but for some reason I don't like to post too much.

With regard to the test, it sounds like you need more time in the seat to gain confidence, although if you can follow the road code, and are reasonably adept at controlling your bike, you should be fine.

Another thing, although I'm an avid 4 stroker, and will definitely argue why they are better, I initially learnt to ride on an ex-racing Pepsi Replica RGV250, and I think I am a better rider for it. I think that the 2 strokes are easier to get the hang of, because you don't need as good throttle control to get smooth control over the bike seeing as there is minimal engine braking (most noticeable at low speed manoeuvering). If you don't wind them up, they are pretty gutless.

I am very surprised at the fact that some people are saying that some of these new generation 250's are that lame that they struggle to get 120. To be quite honest I can probably get close to 90kph on my push bike on a good downhill, and I'd be lucky to have 4Hp for short bursts. (P.S. I am currently a bicycle courier, and one of my workmates who is an absolute machine managed to get 99kph out of his pushbike). As we all know, to gain increased top speed seems to get exponentially harder as it increases, but I've managed to get way off the clock on my CBR250 repeatedly, if the speedo was accurate, it would have been reading about 200kph, but I think it was closer to 190kph with a bit of drafting on Puke. I would love to know what the true top speed of these new 250's is under controlled circumstances, like down the back straight of Puke. I think the VTR250 is a great bike, in some ways better, in some ways worse than the CBR, but I'm sure hoping it could manage a cool 150-160.

A lot of people seem to think that if you aren't riding your bike in the power range, you are doing something wrong. I always cruise around on my CBR250 in 6th gear, even down at 60kph, which means I'm doing 5-6000rpm out of 19,000 which is less than 1/3. There is nothing wrong with this as I don't need it to put out any power while I'm just rolling along, and with the engine turning over less for the same distance you (generally) get better gas mileage, and it just seems more relaxing. If I've got my bike in it's power range, I just want to use it. Seriously, just ride it where it feels like it's relaxing and not vibrating too much. Even if you are doing a high speed run, you shouldn't need to chop it down, if you've got enough safe road then you should be able to just leave it in top and wind it up. The acceleration will only start to noticeably slow down once it gets close to it maximum speed, even if you start winding it up outside of it's power range (some would say powerband, but that seems to be a term just applied to 2 strokes).

Skin off milk, etc.. etc..

[NighthawkNZ]

nah don't postpone the test... as someone else said make a mental note, and adjust your riding habbit to this... go for a few more practise rides before the test...


Good luck on your test
Rubber side down

[SPman]

- I've managed to get the VTR over 130kph in 4th gear
I've seen 153k in top on one of those.........well, it was a demo model.......

[McJim]

I've seen 153k in top on one of those.........well, it was a demo model.......

mmm.....note: I refrained from posting what I've seen in 5th....

[disenfranchised]

I've got a Hyosung too, and though I'm a complete n00b of a rider I've been out on the motorway.

Around 110km/h seems to be the wind vs acceleration point..without hugging the tank that is....(not that I'd drive that fast on my learners occifer)...I'm sure that's more than you'll need for a restricted test

[skelstar]

Never had to hug the tank get to 130km+. Period.

[The Joka]

Don't know what you guys are doing wrong... but no problems with mine!

Kept up reasonably well with 2 x 600cc bikes this weekend just gone, the only time they lost me was when I got stuck behind a cage.. and even that was for less than a minute!

And the other Hyobag :whistle: was doing 150km with out to many probs ... i.e. didn't need a 3km long straight to wind up!:wari:

But I more or less stuck to the rules during breaking in period and even then left it for a while before thrashing it!

[lukelin250]

so just how fast are the ho bags???? im keen to race one !!! umm yeh whoeva the red hobag was riding around taka this arvo and didnt stop to help the two honda riders tryna fix there bikes outside the netball club tutt tutt haahah an no jokes about havn a broken down honda lol the screw came loose on the gear change lever and the lever came off :(

what, the 919 takes 3 mins to get to 140?

[marty]

i took a vtr250 2 up out to raglan, and it happily sat at 130-140, climbed the divi no sweat, and coped with it all admiriably.

and i'm a fat cunt.

Yeah - the VTR is a good 250 - the relatively high torque compensates for the lack of power - would be nice to see a fully faired version with clip on handlebars though as these are the GT250R's advantage over the VTR.

Still the Comet shouldn't be too slow off the mark......

Hey I need a laugh, can you please post a picture of your rear tyre, thanks.
why do you wana see my rear tyre u perv ???

[limbimtimwim]

He is implying you are like this guy.

He's the one with no licence however. And he harped on and on onononononon onon AND ON about Hyobags and then sold it.

[lukelin250]

lol had a hyosung aye? well now he has a "rocketship" so hopefully thats a bit faster than a ho-bag! i cant put up a pic of my rear tyre cuz i just had mine replaced with new ones cuz the tread was all gone from my nice set of dunnys and when i say tread gone i mean everywhere!! still keen to race a ho-bag lol

:Playnice:

[marty]

that is the saddest r6 tyre i've ever seen. GIVE IT TO FIREFIGHT!!!

[SwanTiger]

He's the one with no licence however. And he harped on and on onononononon onon AND ON about Hyobags and then sold it.
Fuck off, I got it back ages ago, and what is wrong with me going on about Hyosung? Do you have a problem? How about I go on and on about fucking your Mummy up the arse with a piece of 4x2 covered in cooking oil.

How dare you.

How about I go on and on about fucking your Mummy up the arse with a piece of 4x2 covered in cooking oil.Well, no one else bothers with the cooking oil. So please, do elaborate.

Start a thread.

[lukelin250]

how about a new thread about how swan tiger is a ho

[SwanTiger]

how about a new thread about how swan tiger is a ho

Or a new thread about how you're such a squid you had to do 180 kmp/h (and lost your license) to keep up with "the bigger bikes" !!

Hold on I'll rub it in ... I could keep up on my Hyosung ... Hmmm ...

You do the Honda name a great injustice.

[lukelin250]

uhh why were you not there? could keep up on the hyosung aye?? yeah goo on ya mate your a real champ,,yeah if you could keep up that would mean you went faster than me and then wouldnt that make you the cock as you trynna put out i am cuzza my speedin?? hmm or does that twist your mind you fuck

[Ixion]

Keep it seemly folks. Biker abusing biker is not a good look.

[lukelin250]

yeah thats true on second thoughts swanny pall meet up for a race sometime?

Because I couldn't be bothered


yeah thats true on second thoughts swanny pall meet up for a race sometime?
Haha no

Don't take it personally jandals, been where you are on the same ride, I'm just pulling your chain

[lukelin250]

ahahh i no bro im just givin you shit,,sucks huh,,hah howd you get nabbed mate?

[Morcs]

So both you guys lost you licenses?

So did I. should start a club...
