250 vs Boy Racer

[Brett]

I agree, most 250's will do a quarter mile time that is as good as most 4cyl turbo's. However most of that is straight off the line for the first 100m. Then the car starts to reel them in a bit. End result is that they both finish about the same.
Had a few plays with 250's in my 200sx, they never came close. I know my ZXR would have been eaten by the cage.

Anyone see that mazda...doing a run..down the quater...
Thought it did a 7.6....i may of heard wrong...seems affully fast for a rotary..
Dont think the Busa does that...........

1.15 on a CBR250 fuck me that's fast. You must have been standing that thing on it's front braking to get that time... How many meters out was your braking point for the hairpin on the CBR250 by the way?

Hehe, thanks. Was my first ever race day and second time on a track, and yes it wanted to stand on the front wheel constantly. Got to 1:15.12 Braking from 200kph (indicated more likely 185kph) from the 100m marker. It helped that I was able to hook on the back of Quasi's GSXR400 and draft. His 400 wasn't running all that great I don't think, and he was a heavy loaf. Most other people seemed to brake from 200m out.

Just won 3/3 of my 250 superlite fourstroke races over here at Winton on Sunday just gone by a comfortable margin. $200 prize money thank you very much. Write up to come I was also the youngest in the field. A few experienced racers like the class over here because it's cheap and fun and comparatively safe. And because we are thrown in with formula 3, there's plenty of battles to be had with 400's 650's and 250 2 strokes. Had an absolute blast. Winton kicks arse for the smaller bikes. Spent most of my time in one race wrestling with a motard (this time I cut him up )
In the latter races battled with an RGV250 and an SV650.

Still in the interclub races I got lapped by the superbikes after 6 laps :P Was a bit dodgy but the marshalls let us know when they were coming so we could get out of the way.

One thing to remember when braging "I bet xxxx car on my 250" is you mostly likely filtered through the traffic and blocked them so they're forced to take off with you in the way. I would say (opinion here) that a WRX / EVO or any 4x4 Turbo can put far more power down off the line than than a run of the mill 250. I can't open up my 1000 off the line ever, doesn't matter how much weight I get over the front it would simply flip the bike.

As an owner of numerous 250's and an Evo 4. Nope. To launch an evo4 as hard as you can launch a 250, you will break things in the gearbox/clutch.

The 600's don't flip when launching them 0-100 in under 3.0 seconds. The 250 isn't going to flip if you've got good clutch control... Learn to slip your clutch properly. The 250 is quicker to 80 than my evo4. On the 250's I've never blown an engine a clutch or a gearbox.

My clutch was failing on my evo4 when it got stolen.

Evo 4's are puss. still go alright but i mean my mums Caldina just as quick.

but every one know's evo 4's are the slowest evo. and yeh slipping the clutch at 13-14,000 rpm on a 250 wont flip the bike and does laung pretty much anything.

Have u riden a decent 250?? i saw in another thread a comenting you where making about 250's ..

yeh there not quick but there not as slow as your making them out to be.
I can manage to get all 42hp or so of my hornet down to the ground no problems with out to much effort, and its not hard sliping the clutch on it at all most full throtle to get of the mark quickly.

Launch a 4wd turbo car a few times start saying goodbye to gear's dif's transfer cases clutches you name it they will break it eventually but after countless launches on my lil slow 250 it still does them no sweat.

And yes I can get a jump on a friends STi from the lights if he giving it a moderate launch and still get it up to 80kmph , Verrryyy fast sti

I agree with you guys... i've seen that other filternz guys comments on 250's as well and he obviously can't launch properly... you can get a bike off of the line very quickly and like it has been said many times now, you just need to know how to ride it properly to be launching it on par with the jap 4wds. Bikes have tons of performance advantage when it comes to a standing start...

Sounds like you really know how to brake man... good stuff! That's where the real fun is!! that's where the real riders are seperated from the rest isn't it... . Shit have you locked the front braking from that 100m mark yet?

...Speaking of which- have you guys done any braking vs cars? I know my NC30 than stop fucking quickly but i've only gone up against a skyline r34 GTS-T and came even braking from 100kph... still that thing has ABS and can brake really well...

I know cbr1000 with a decent rider can go from over 140mph to 40mph in 4 secs which is cracking I thought....

Yeah, I've locked up on Pukekohe coming into the hairpin. The trick is to get off and back on. For some reason when I'm racing and my adrenalin is right up there, it all happens without really needing to think about it. Raced 600's aswell, and regularly locked that up. At maximum braking small bumps on the surface can cut the front loose. To know how hard you can brake without locking up you need to lock up a few times. Just make sure you are starting to back off the brakes as you start to lean in, that's when most of my lowsides have happened. Locked the front at Winton a couple of times on Sunday on my CBR250RR. That surface was a bit dodgy in places.

I think a car with equally high quality tyres will actually be able to brake faster. My Honda Prelude used to stick like shit to a blanket on it's Dunlop Formula FM901's. I reckon that would be quicker around Puke than the CBR250RR as long as I removed the speed limiter.

Although with repeated braking, road cars will start to fade pretty bad. I even got my dad's Hayabusa to brake fade on Taupo. Gave me the shits, the brake lever started coming back to the bar at the end of the front straight. But that was repeated braking from well over 250k/hr, and I was sort of racing against Leong on his trick little K6 GSXR600 (just quietly I was slightly faster than him)

Yeah actually this gts-t had worn tyres so it probably could have stopped a bit faster come to think about it.

To clarify, I did said my 1000 would flip, not the 250. My Hyo250 I would have said was pretty decent but they’re a fairly lazy 30hp and heavy to boot; It’s hard to even wheelie the Hyo let alone flip it.
I have an 07 Holden Commodore, the v6 model and sure the hyo got the jump on the line but the Holden was next to me at 100. (wife driving the Holden)
I can only talk from my own experience so save me the “have you ridden a decent xxxx” or “you can’t ride” comments. I’ve had two Mistsi VR4’s (2.0 TT and 2.5TT), and two Vtec Preludes all various mods, none of which were super quick but they give me a good comparison to comment on and I would’ve been looking at the Hyosung250GTR in the mirror in all of them at 100km.h.
Bikes in general are quick for sure but I think the tone of this thread is over-rating 250cc bikes. With the odd exception, after 80km.h any mediocre sports car will eat you.

it was a hyosung...... i rarely can even spot them in the rear vision mirror.. I usually try to wipe my mirror thinking its dirty at 0-100.. jks but seriously a hyo got nothing on a cbrr or zxr 250 got nothing a hornet either ( im not tryna talk the bike up )

mums caldina shits on a v6 commy ( i used to work for holden I know them well ) yeh ive owned quicker cars but would be a quick car to beat a high specd 250 to 80km pretty decent even to 100km

[racefactory]

agreed- those hyosungs are not only weak but heavy too... there are many videos and records of CBR and ZXR doing quarter miles same/faster than turbo japs (stockers)... so to say they will ''eat those 250s'' is pretty over the top...

[Delerium]

around a track (silverstone) a car (GT3) is quicker than a bike (race spec R1) It comes down to how much rubber is on the road. I watch too much jeremy clarkson
