Can a KTM 250SX be converted to a 300SX?
The 300SX engine kit is a straightforward swap-out of the top-end. You don’t reuse any of the old parts from the 250cc top-end. For a backyard mechanic, the most difficult part of installing the 300 kit would be draining the coolant (which is pretty easy).
What kind of pistons are in a KTM?

Base gaskets and O-rings: There are four thicknesses of gaskets for proper tuning and clearance. In the past, consumers could buy a KTM 300SX at their local dealership, but KTM consolidated that bike into a bolt-on aftermarket kit.
