This is the best kit we offer for the KX65 ATV national classes.   The KX70 stroker increases the power across the board so it is not just all top end.  The stroker crank gives it torque out of the hole  for grabbing holeshots and provides something if the rider falls off the pipe or misses a shift.

The KX70 uses a shelf stock KX65 piston kit so they are readily available anywhere.   If need be you can also use an OEM piston kit.   However if you buy the Wiseco kits from us we keep them in stock and sell them to you for dealer cost.

If you really want more check out the KX76 cc big bore / stroker.  Those are the fastest thing we offer for the KX65. They use the same bottom end as the KX70 but top ends are bigger and make even more power.  We can easily set up an additional top end at the same time.  Just sayin.
