Ski-Doo claims a single-ring piston has less drag, which allows the engine to rev quicker at low engine rpm. The revised piston ring was manufactured to an out-of-round shape, so that it would exert even pressure once installed in the cylinder. $39.99 $ 39. Here are some tips for a Vertex Piston for 2-stroke piston installation.
