It's the weight that holds the ZZR's back - and most 250's don't have much room for modding...

justsomeguy

6th March 2005, 21:49

Really..... it only weighs around 150kg.......

I should just save up for a bigger bike and concentrate on only learning here......

Lots of people have told me thats it's a crappy handling heavy bike....... but I figure if I can get some pace on a crappy handling heavy bike then it will make me a better rider than learning on a fast light bike...........

Whaddyatink????:spudwhat:

Remember it's more rider than the bike.

I would keep it standard. If you want more power upgrade to a 400 when you can.

ZZR is a great bike, slap a 2into one exhaust on it and you will enjoy riding again - I constently hit the limiter on mine, it never skipped a beat - they are great bikes and are awsome in the corners, although I dont like its skinny front though. :niceone:

Bang a NOS kit in it. Its good for a few ponies. If some guy can do it to a scooter, a 250 should be no worries

Pretty inefficent - prob wouldnt be as bad with some fuel injection - but turbos, to much heat - to leathal, I saw a GSX turbo'd it was nuts like 600hp - it was just beyond the world - It blew up though. :done:

Dont be scared to chuck her/him into the corners - he/she loves it - just make sure your in the right gear before entry nothing worse than no go out of the corner, just keep within your limits - the bike has a amazing centre of gravity it never ever got flakey with me in the corners.

Well - the ZZR is a crap load more comfortable, and the ZZR felt more 'in' the corner - the zxr just doesnt feel like its turning in.

But as for acceleration, and top speed - the ZXR is amazing, acceleration pushes you very hard into the back of the seat and often wheelies all the time, top speed is also amazing where the ZZR stopped this thing keeps going and going and going over 180 - its really amazing, accelerates with pleasure to 170 then slows its acceleration abit til 180. :yeah:

you have to massivly[sic] countersteer it out [of the corner]Are you sure you're talking about a ZXR250 here, and not getting mixed up with say, a ZX10R?

Mr Skid

Maybe he's the lucky owner of a stealth rebadged ZX10R. I wish my generic 250 multi required countersteering in corners. Well it does, but that's only when I take it out on gravel.

Anyway don't you need to go to bed now so you can get up early and get dressed......
um. yeah. ok. :unsure:

Hi yawl

Just wondering if there is anything I can do to my bike to make it a bit faster??

The simpler way would be to sell it and buy a CBR, ZXR, etc I guess......

But I've spent a lot of cash getting it serviced and repaired and it is mechanically mint........

However I think I could do with a bit more pace......

Another thing worth mentioning...... I rarely ride past 12,000rpm cos I'm scared of breaking something...and usually hover in the 9-11,000 range...how much higher in the rev range can I go??

Lots of people have told me thats it's a crappy handling heavy bike....... but I figure if I can get some pace on a crappy handling heavy bike then it will make me a better rider than learning on a fast light bike...........

Whaddyatink????:spudwhat:
Ride downhill:lol:

Dont brake for corners, Serious tho, start pushing the limit a little at a time. Not saying be an idiot just push yourself more than the bike. Make YOU go faster.:niceone:

The ZZR seems to want to be in the corner - like it holds itself better doesnt flick as easily, where as the ZXR just seems like its going to slide and is wayyy to flicky.

Its probably me, but the ZXR seems to swoop into the corners to suddenly and you have to massivly countersteer it out, were as the ZZR would dip in slowly with the corner and straighten herself up nice ready for the next.

Ummmm if you could wheelie your zxr without dumping the clutch hard then i'd be pretty amazed. As for cornering well i owned a vt250 before the zxr250 (pretty similat to a zzr) and well the zxr corners a hell of a lot better in my opinion. The vt had more torque coming out of the corners but the zxr just wanted to be pushed hard into/through them. You just have to have good rubber and sure it's flickable but good rubber will keep you stuck to the road. Saying this though i rode mine untill i needed more power (dipped into a corner and rolled right off the front wheel ..... shouldv'e had sliders) zxr's are awsome and can put bigger bikes to shame in the twisties. Will probably see you on sat. Cheers

A decent exhaust and an aftermarket air filter will help heaps, k&n make a jet kit for them or you could re-jet the carbs yourself.... either way let it breath and they go hard as!
i hit my rev limiter regularly (15500 rpm so shouldnt break anything!), still goes allrighty 2 up too, just watch for scraping the exhaust on the twisties........ (maybe i should get sum of those slider things for under the pegs....)

have you adjusted your suspension? it makes heaps of difference, i have mine one down from the hardest, with sum sticky rubber it can go faster round corners than i can at the mo...... less than a cm left on ma chicken strips tho and ive destroyed the sliders on my boots, (ride on the balls of ur feet if ya wanna lean further....)

justsomeguy (member.php?u=1378)
i had a 96 zzr250 for a good 4-4 1/2 years, done a good 50,000kms on that, taught 3 people how to ride on it.
Mine spend most of its a good 40,000kms of that above 11,000rpm.

Me and the wife(gf at at time) did 800kms in one day on it. Just learn to ride it being in the right gear coming in to corners, and put on power early enough to give you a good pull out. If you steriously start pushing it i would avise you to take the center stand off.

My wife went to a bike rally with a friend on the back with her father in law, she was blowly away guys on harleys & buells, they though that the bike was 600 when they got told it was only a 250, that god bumed, i mean most these guys who 30ish bikers with harleys, who think they are shit hot, being blown away by two chicks two up on a red and pink zzr250.
Don't worry about modding it they got plenty of power, a bigger bike will lose you in the straights, but you can carry a shit load of corner speed. I looked at going down same road modding it abit, its not really worth it. As long as you service it every 5000-6000kms, it should be sweet.

You can't, absolutely, no way, no how, steer ANY two wheeled vehicle travelling at more than 15km/hr without counter steering. Unless you have your "Anti-Laws-Of-Physics" field generator on. Even using just body weight is actually inducing a counter steering action.

I think you need to do some reading about counter steering and what it actually is. And before you go, "But I lean my bike into corners, you dimwit", I think you need to do some reading about counter steering.

Tell you what, next time you want to steer left at 100km/hr turn the bars left. Pull the left hand bar towards you, and push the right hand bar away from you. When you get unwedged from the car on your RIGHT, let me know how it went.

Buy a faster bike. Learn to ride the ZZR faster through corners. Go for a ride with Stew from TSS in Lower Hutt, get him to take a TL1000S and swap with you for the ride, and then stare in disbelief as he leaves you for dead.

But seriously, the only way to make a 250 appreciably faster in a straight line is to sell it and buy, say, a 600.

Gyroscopic precession? I *might* have a vague understanding by now..

Talk of "massive counter steering" for me conjures images of the back wheel attempting to overtake the front, and subsequent steering inputs. But then if we wanted to be precise, that'd be refered to as counter-counter-steering.

I was assuming this was what John was getting at, as I couldn't see a ZXR needing any more [counter] steering input than a ZZR. If we were to assume that the forks on a ZZR had more rake than a ZXR, as befits a sports tourer vs a sports bike I'd expect less steering input to be required for a given corner.

What say you?

John

7th March 2005, 10:10

I say all this gyroscopic forces talk makes me feel hot.

But I did forget to metion I was riding it with fucked fork seals so that may change alot of stuff, like the wheelie crap cuz there is no real strong downward force on the front wheel with the weight transfer.

And I'm pretty sure that the leaking forks would explain the huge use of countersteering.

You're talking about over-steer.

justsomeguy

8th March 2005, 06:48

I see what you'll are saying........

I guess I need to focus on the correct gear selection around the twisties.....

Sometimes I'm down in third and at full throttle waiting for some go to kick in ........second gear and it just makes noise but doesnt do much else......

and I'm sure I can still lean more be a bit more agressive in corners.........

Lets see will ask some of the bigger fellas this weekend......:niceone:

8th March 2005, 08:02

You're talking about over-steer.

over-steer is when there is no traction on the rear wheel and it begins to slide/spin and try to overtake the front.........this is where counter steer is used -countering the angle of slide- while holding power on so as to regain traction at the rear wheel without "over correcting" -counter steering too far resulting in bodies gettin freindly with the road-

justsomeguy- sounds like you will be able to push your bike a fair bit further than you have. i find between 10-14000 rpms the most fun on the ZZR th "Z Zone" just try not to run out of revs on a corner.......

see if you can keep up to some of the guys on bigger bikes, easily acheivable for the bike through twisty roads and knowing the bike will do it takes away a fair bit of the paranoia "ie the guy in front of me hit that corner at 90 i'll jst hold the f*** on and hope for the best........

Over the years I have found it can sometimes be more fun riding a little bike fast rather than cheating? and using horsepower. Practice and show us horsepower cheats how to ride. You can do it. I'm still learning that the biggest handicap we have is our minds.:niceone:

BS - Countersteer is what you do every time you go round a corner on a bike. You're just talking about correcting oversteer.

John, how hard have you rev'd your ZXR? Supposedly the CBR is meant to be limited to 18000 isn't it, but I've been up to/over 21000

Well I've had it to 2100 or sumthing? (end of the tach).

But I hear that the tachos are overasumptious so that people dont go over 18500rpm so they add a few thousand to the speedo.

i.e it says your doing 16000, when you are actually doing 14000 or something - but I'm not entirely sure.

At the track day at Manfield, the bike will sart to idle at 18500. I only went further than that cause the rear wheel decided to jump a meter to the right on a corner and I managed to find false neutral between 3 and 4 (that jump was bloody awesome though)

Its a shame I took the front fairing off cause that was really slowing me down that day. I might manage top speed next time with the fairing on

John

13th March 2005, 14:57

False neutrals suck when you are going round a corner and it just slips in. Then you try find a gear and keep the corner speed up without lighting the rear wheel.

Idling at 18500? man - is that a human idle speed or after startup? :P

Coyote

Wrong word I guess by your answer :rolleyes:

18500 was as far as I could rev it whilst accelerating. I was doing about 160 in 5th, and the wind wasn't letting me go much faster as there was nothing up front to deflect it

Hey guys you'll better pipe down on revving your bikes.........

Looks like I've blown some gasket or seal on mine........

After yesterdays trying to keep up with them 600's and todays blast trying to get to the Toy run and back....... something went poop:spudwhat:

Went through 1.5 litres of oil from 8am to 4pm today............

So I've got some cleaning to do, to find that leak........... and I gotta hurry up if I'm gonna make the Ride Safe thingy next Sunday..............

So I'm a gonna be a real busy typa person:brick:

OK but only $160?? Even my baby elephant of a bike manages that........... must of been a pretty strong head wind...... were you crouched right down??

Mini-me was easily hitting bout $180 yesterday on his ZXR 2fiddy........

John

13th March 2005, 15:13

Is there any smoke coming out of your exhaust?

Becuase if there isnt then you are lucky (sort of?!), check the underpan - check your oil filter and oil release valve cap, good luck with finding the leak

Seeing you fly by like that was impressive..... especially on your 2fiddy unlike others on thier monsters......:2thumbsup

John

13th March 2005, 15:46

It looked like there were a couple of rastafarians having a smoke down there......

And I was dropping around 5 tablespoons of oil every time I stopped for a red light.......

The stuff has pooled up under the engine on to the bottom of the fairing........

Quite a few drops all over my rear tyre too...... things a bloody mess

Take it to a shop mate you might have a poopd piston ring or maybe your valves clapped :(

:spudwhat:

Hope it works out ok though!

Mini_Me was that ZXR nz new I forgot to ask you yesterday - only the dyno mine cut at 195 so just wondering (mines a fresh jappa)

My dad was paranoid of me falling and destroying the fairings, so I took them all of, so it wasn't very aerodynamic. The wind was hitting the speedo and tacho, and my helmet was being pushed up and I was being strangled. I'll leave them on next time and get some nylon bungs to protect them (Manfield Winter Series :2thumbsup)

Not anymore, after that, I've fallen a number of times, and tried using model glue to fix them. Worked for the mirror support thingy, but not for the fairings.

Also, at the track day, I might've been able to go faster without the fairings if i wasn't for the stupid pace bike, everytime I got to 160, I had to pull back to 120 :angry2:

I THINK it was an import. Seem to remember seeing some red baron documentation on the owners form when I bought it from a dude in Whangaparoa. Its always been a rowdy little beggar and It was nice to see it still being thrashed yesterday and not letting us 600's have it all their own way :)

i just got a 96 zzr 250, has been going great! i was wondering about how to make it go faster. but then i went for a ride today with about 30 guys n gals around the central north island and i could keep up pretty well. i would be riding with all these bigger bikes in the straights and then when the twistes came after about 5 mins i looked back and no one was there, so it can hold its own, but in saying that after the twisties all these bigger bikes wer crusing at about $140 and it was pretty hard to keep up. so yeah it was real good. ive started wondering about ajusting the rear susp. (not sure how to yet) and lil things like that. i should probly get it serviced too, its done 50k and seems to be right, but i wont be happy till i no wot sorta condition its in. seems to go alright tho. good luck with your bike tho, hope it doesnt cost too much!! (p.s does anyone know where i can get a cheap pair of second hand zzr250 pipes from, mine are a bit naft!)
