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
 
Honda TRX250R

Ok cool I still wouldn't have to put lead on. I'm over superheavy animal weight running with 375 pounders. I think I'd be good at it.

cr250 are 2 stroke dirt bike engines. the trx250r was the old faithful 2stroke quads that everyone went crazy with on the racing scene. made from 86 to 89. The rules say max 255cc on the 2strokes. A 67.5 bore with stock stroke comes to 257.65 so has to be under a 1.5 over for sure. Don't know the exacts for 255 but hope this helps ya.
