i suppose the stock balster engine suffice
Will a 94 rm 125 engine fit on a 2000 rm frame?
Any tyre that will fit the rim and clear the frame.
No, the crank shaft in the 450r is bigger than the 230f therefore the crankcases are bigger. The frame will not match up to the engine. only a engine intended for that frame will fit, however other year models will fit.
If You modify the frame it should.
the engine will fit,but you may have to swap computers to match
This is possible with some minor modifications to the bike's frame.
Yes you can but, depending on your frame, you'd need a shim to get the post to fit your frame.
Perhaps 15" to 16" high at the crotch.
if you modify the frame it will
Yes, you can.
