Anyone remember how many overbores you can go on a TRX250R before its illegal ?
A lot. You would have to be 511cc to be illegal
Unless your referring to staying under the original combination before going into the 430 weight zone?
If that's the case, I think its 310? But don't quote me on that just yet
cr250 are the 4strokes , like jimbos old motor. TRX250r were Hondas 2 Strokes...sorry Bobby I didnt clarify that.
