Yamaha YZ 250 F (CG 25) [2006] - forged pistons

PROX forged pistons for the Yamaha YZ 250 F from 2006

The PROX forged piston is assigned to the Yamaha YZ 250 F (CG 25) from 2006. Its forged design made of a special aluminum alloy is designed to function reliably in the engine. The alloy helps to minimize friction and thus creates a resilient basis for use in the upper engine area.

Function and execution

As a forged piston, the component combines the specified standard piston compression with a precisely defined geometry. The design as a hollow piston with 5 valve pockets takes into account the design features of the associated engine. The piston diameter is 76.95 mm.
