Top speed of xr200r? And xr250r?

Recommended Posts

we have a couple mid 90's xr200's we use for farm bikes ive been able to get them upto 55-65mph with me on it though im just over 230 pounds so its takes a while / my buddy is about 100 pounds lighter then me and can get them up there much faster

 

not sure if they have stock sprockets on them though i know one has a 50t rear and i think the other has a 53t rear

My '99 xr250 will do 70 on the road if you keep it pinned long enough. That's barely pulling 6th gear, it'll never get over 70mph. I'm guessing that it's 14/46 (edit: 14 might be lower than stock, so it's poss 12/) now, I know for sure it's geared higher than stock but don't have the bike in front of me to check. Also engine is stock, except for exhaust tip.

My '91 xr100 did 45 stock gearing stock engine, no more power to pull a higher gear (I tried that once)

A well tuned and mildly modified XR200R will top 70mph.  A XR250 with a 300 kit will easily top 80mph with 14/45 gearing. 78mph with stock gearing.

I have gotten GPS 70mph sitting up with a slightly modded XR200. 0.5mm overbore, 10.5:1 CR, and with 13/49 gearing and big 4.00R18 Trials tire calculates to 9300rpm.

Even faster if you have a the 91-95 XR250L gearing in the trans on that generation XR.  I'm not sure if that wider ratio gear box fits newer models.
