fast/slow? - Page 2

i dont think a 125 could go 90 no matter what, maybe 85, maybe, if you put gearing on it, and even then you would have to have someone push you to get started, and btw, engine mods dont make it go faster top speed wise, even a bore kit wont make the top speed any faster. they only help with the acceleration and how the power is delivered. my bike go 73, and that is pretty damn slow.

Really what do you need to go that fast on a dirt bike for. There is not very much riding you will do where you require speed like that. Unless all you are riding are fire roads... And that is just unsafe to go that quickly even on a gravel forest highway :O

wr250f95 · 06-06-2008, 08:43 PM

and if your doing fire roads your weapon of choice is a xr650 or a wr450/crf450x

gscx · 06-06-2008, 09:03 PM

well the fact of the matter is that 125s dont go 90mph haha.

wr250f95 · 06-06-2008, 09:13 PM

exactly, when a wr250f with gearing struggles to reach that.

turtlemann14 · 06-07-2008, 10:58 AM

is a 450 geared for 90?
(wide ratio gearbox)

wr250f95 · 06-07-2008, 11:00 AM

a 450f would break 100 if it had no rider or weight.

during an enduro we had a easy section that was just all fire roads for like 5 miles. To get us from trail a to trail b. Well I was exactly on my minute and wanted to get a little ahead since there was not going to be another check point for awhile. My enduro computer read my top speed for that race at 78 mph. I was on my yz400f. I was not pushing it all the way as at that speed on the gravel road I started to get a bit of head shake so I was not going to push it any harder.

wr250f95 · 06-07-2008, 11:08 AM

those 400's were almost perfect between performance, and reliabilty, their only draw back was frame geometry, i would love to have a wr400 or yz400.

well i got my rm 125 up to almost 75 on the highway that was just before she seized on me, its a 2 stroke you dont wanna be winded her up like that any way trust me i learned my lesson lol, i should have listened to my buddy 2 stroke = speed now not long term
