Re: KDX 200 engine in a 125 frame??
what i was saying is the xr motor(4 stroke) makes sense going into the yz frame(light and small better suspension). but taking a 220 two stroke and putting it into a 250 two stroke frame doesnt make sense to me. why u wouldnt just put a flywheel weight, port, put a torque pipe, light and other misc goods to the existing 125 or 250. this would be cheaper and easier if u ask me. but that is my opinion, maybe the kdx has a gearing advantage i dont know. just seems like u could do alot more with an existing bike
