JE Pistons Yamaha YZ450F Pro Series 2 Ring 12:80:1 97MM Bore Piston Kit

In this JE Pistons Pro Series 2 Ring Piston Kit, you get the piston itself, a set of rings, the wrist pin, and the necessary clips to get it installed. This kit is built for the Yamaha YZ450F, WR450F, and YZ450FX models from 2014-2017, giving you a direct replacement for your engine's core component.

This piston is designed with a 12.80:1 compression ratio, which is a notable increase over stock.
