Product Details

The Wiseco 4858M07700 is a Pro-Lite forged piston kit engineered for the Yamaha YZ250F, featuring a 77.00mm standard bore and a high-compression 13.5:1 compression ratio.

Wiseco is the only aftermarket piston manufacturer in the United States that produces pistons exclusively using the forging process, resulting in improved tensile strength and a longer service life compared to cast alternatives. Each piston is engineered, forged, and machined in the USA at Wiseco's facility in Mentor, Ohio.
