ASK THE MXPERTS: TRADING TWO-STROKE DISPLACEMENT
Click on image to enlarge
KTM, and by proxy Husqvarna, makes a bolt-on kit to turn a 250 SX or TC250 in a 300. It is almost always back ordered.
I have a Husqvarna TC250 two-stroke, but now that I have it, I think that I would have been better off with a KTM 300XC. Is there anyway to turn my 250 Husky into a 300 KTM?
Yes. Virtually every engine part needed to turn a KTM or Husqvarna 250cc two-stroke into a 300cc two-stroke is available in kit form from the KTM Powerparts catalog. The 300 kit includes a new cylinder, head, piston, rings, gaskets, power valve and black box. It bolts on. The retail price is approximately $900.
