yeah i had a cr 125 and i would be riding on an old road that was next to the interstate and i could look over and i would be passing some of the slow cars on the intersate.
btw a two stroke has more top end than a four stroke but a four stroke has gobs more torque

ya i no even on my cr80 it felt like i was flying. so i would think a kx250 with a full exhaust and it says it has a little bit of motor work done but not sure what would do way faster than 70-75mph.

ok i see. i thought that you were thinking that it wouldn't go that fast. i agree but if it doesn't have any gearing changes then it won't be any faster on top end unless it couldn't pull the stock gearing

I think the kx250 will do 70-72 tops. My cr125r would do around 67mph so I have to guess the kx250 would do 72mph.

im talkign abotu the two stroke kx250. wiht a ful exhaust and a little bit of engine work but not sure what. in my opinion i think it will do way faster than a cr125, so i think it will top out fast than 72
