performance of a 250 4 stroke

[Atomic]

you'd be throwing your bike away every corner if it only had the contact patch of a 10 speed. 10mm...

Are you forgetting that a motorcycle tyre is circular?
A 10 speed has a tyre not much wider than 10mm but it certainly does not have 10mm of contact. Just as a motorcycle does not use its 90 - 180mm of rubber, as my bike is sitting on its stand in the garage there is only 20mm of rubber touching the ground and thats not pushing it to its edge at full lean.

the YZF has some good sized rubber, 180/55/17 on the rear 120/70/17 on the front, I went with 7cm just to be kind to the bikes, it's probably less in real life, but I wanted to give the bikes a fighting chance in the stats...

I think the start of this argument is about road accleration of the 250 vs turbos, and having had experience with both, I think I can sum it up fairly unbiased, my evo IV vs my CBR250RR 0-80k/hr would be about the same, and yes the evo was modded although running standard boost. Around about 5.5 0-100 for both. After 100k/hr the bike is not in the picture though, so as the argument was initially about on the road acceleration I think it's fair to say that the 250 4stroke is definitely worth having... And my RGV would have comfortably beaten both. 400m and the speed gets too high for the 250 four stroke, so its not a fair comparison for road driving.

And as far as cornering goes, my evo had Teins and could out corner the bike probably most of the time except for chicanes, cause the bike doesn't have to go as far.

I drive a 1.3L rwd corolla wagon (ran a 17.917 at 119kms :spudbooge ) and could probly skin most big heavy turbos over piecocks! !
spent sum time nd money on suspension, brakes and tyres!
(plus a few lessons on how to drive it...... ...)

i reckon i could beat myself on my ZZR250 now tho!... on a good day purely cos its got more pull outa corners and thers so much less weight to transfer through the chicanes.
a sweepers a diff story but throwing it round i like the bike! !

however the supersticky rubber means my rolla will (safely) do similar times in the wet with gravel etc on th road...... while staying warm and dry........crankin th beats.......
pity its in the shop for a while..............

hang on i've got a bike outside and its sunny.............

ha ha..

I drive a carina wagon, all of 2.0 of them there litres. I reckon it could top your corolla wagon any day. I'd be on for a 20s 1/4 which must be better coz the numbers are bigger
