0-100

[DMNTD:Me]

That VTR can HAUL!
Wonder what an sv1000 would be like

I shall tell you in the next couple of days....how's that?
Oh and if I can sort my shit out I'll get it on vid

Been thinking of doing up one of those small 49cc pod bikes and trying it on the 1/4 mile if allowed. Anyone done this yet?
Should be good for a laugh or two.

LOL...I got a Magic mate. Keen as on a 50cc drag/walk as long as there's no hurry!

Woohoo! my bike is finaly fast at something, Go Honda!

[Forest]

No it doesn't Pin on redline, dump clutch, clutchless shift at redline.

Why would you change gear at the redline?

If maximum acceleration is the goal, wouldn't it make more sense to change gear shortly after you've gone past the engine's maximum torque point?

[Jamezo]

Not necessarily, especially on a peaky bike like an NSR, where the power in the over-run range (which is small anyway) is higher than that the power in the range that you'd be in when you shifted up.

ZXR250A < CBR250RR (MC22) < ZXR250C

that was on a ride with my mates, though i am about 15-20kg heavier than them.

That was full throttle from 100kmh to max speed on a straight (private road )

Not seen ZXR250C vs CBR250RR in a 400m drag, but from the comparison of Texmo and vtec in streetstock racing the CBR is a tad faster, but that is most likely due to vtec's 25kg weight advantage.

That late model FZR250RR (not sure on year or model designation but im thinking its 1993) is apparently the most powerful 250, but there arent many in NZ, was supposedly out to 48-50hp at crank, but that may just be a load of ass, i've never seen one though so i wouldnt know.

fuck off. fzr....pffft. my rs250 was dyno @ 67rwhp. that's with a tyga exhaust and modifying the heads to take the plug vertical instead of angled (for streetuse). running 98. i think stock they are about 62

One of the other vids by those dudes on YouTube had a 250 doing 0-100 with an 80kg rider and again with a 50kg rider.

50kg: 8 secs
80kg: 9.6 secs

Take from that what you will.

[Waylander]

I did feel smoother, so long as you quickly hit the gas straight after. Otherwise it felt like it was snatching

Yea or if you have to engine brake soon after it get's kinda clunky.

[crazefox]

Ha ha i like it

good point,on sucha light bike with not the most torque or horse,rider weight does go a long way in speed variation, im fairly light and my mate is close to 100kg but on a faster bike,id say id probably win a 0-100km

[lukelin250]

Never did try my ZZR1100 for the 0-70 mph time when in the UK, I did often take it to the dragstrip at Santa Pod.

wow shit santa pod? dude i didnt know that drag strip was still around,my old man used to drag race there back in the 70's and won a few titles,he had a yellow mach 1 mustang was pretty nice for a cage!! santa pod thatd bring back some memories for him lol

No. In fact its often faster to shift after the maximum power point. It depends on the gearing and the engine. It's all about torque at the wheels.

[Mr. Peanut]

Not necessarily, especially on a peaky bike like an NSR, where the power in the over-run range (which is small anyway) is higher than that the power in the range that you'd be in when you shifted up.

NSRs are not peaky. Almost linear power delivery.

[lukelin250]

ill trust what you say since you own one but linear power on a 2stroke?? isnt it all about having a powerband?

[Mr. Peanut]

Yes, this is were the advent of powervalves come in, they restrict exhaust flow at lower RPM giving you more torque; essentially emulating a smaller exhaust port.

The NSR has an exceptionally good system, hence a virtually linear power delivery.
