The WÖSSNER forged piston (manufacturer reference 8147DA) is designed for motocross riders seeking a quality replacement part for their 2 or 4-stroke engine. Manufactured in Germany by Wössner, this aluminum piston is precisely machined and features an anti-friction treatment on the skirt to reduce friction and wear against the cylinder.
Designed for the motocross world, this piston is suitable for engines mounted on the listed machines (GAS GAS MC 85, KTM 85 SX, and HUSQVARNA TC 85 — mentioned versions). Its finish and the supplied components facilitate the restoration of the top-end: installation of the ring and locking with circlips, pin installation included. Ideal for an engine rebuild when the bore corresponds to the indicated oversize A.
For installation, check the exact bore diameter and follow the manufacturer's recommendations for your cylinder for fitting and break-in.
