Features

WÖSSNER Forged Piston – Manufacturer Ref. 8724DA

Forged piston designed for quad engines, manufactured in Germany by Wössner, a recognized specialist in engine parts for 2 and 4-stroke engines. Made from aluminum, it features a skirt with a treated anti-friction finish and is delivered complete with ring(s), circlips, and pin for easy installation.

Diameter of bore: 74.00 mm
Piston diameter: Ø 73.95 mm
Oversize letter: A
Material: Forged aluminum
Number of rings: 3
Delivered with: rings, circlips, and pin

This piston is aimed at quad enthusiasts and workshops looking for a standard engine part suitable for replacement operations during a re-bore with oversize A. Its treated skirt minimizes friction against the cylinder and facilitates initial break-in.

Notable compatibility: particularly suited for YAMAHA YFM 250 RAPTOR 2WD (2011–2013, 250 cm3). Before installation, check the bore dimensions and manufacturer tolerances, as well as the condition of the cylinder and rings. Installation and tolerance checks are recommended to be performed by a professional.
