Yamaha YZ 250 (CG 12) [2002] - cast pistons

PROX cast piston for Yamaha YZ 250 (CG 12) built in 2002

The PROX cast piston is designed as a replacement for the Yamaha YZ 250 (CG 12) built in 2002. Its standard compression and defined design make it easier to choose for an appropriate repair of the upper engine area.

Function and execution

The piston made of aluminum has a curved piston shape as well as a lamella cutout and suction hole. The MoS2 skirt coating is designed to reduce friction in the cylinder. The design thus combines the equivalent original equipment quality intended for replacement with a functionally coordinated surface.
