WÖSSNER Cast Piston (Manufacturer part number 8101D100)

Cast aluminum piston designed for engine restoration of quads. Wössner offers a reliable original part, machined to the appropriate tolerances to maintain the necessary sealing and piston-cylinder clearance for proper operation. Supplied complete with rings, circlips, and pin, it allows for quick installation during a rebuild or top-end repair.

Designed to restore original clearances and geometry, this piston is intended for builds that adhere to manufacturer specifications. Its machining and skirt treatment reduce friction during heating and facilitate break-in. Ideal for common repairs, it is particularly suitable for Yamaha YFS 200 Blaster models (2004–2006).
