DescriptionWossner forged Piston kit

Product details :

Features

Manufacturer's ref: 8115D150 — WÖSSNER forged piston, designed for motocross machines. Made in Germany by Wössner, a specialist in engine parts for 2 and 4 strokes, this piston is aimed at demanding riders looking for a robust and precise replacement part for their vintage YZ125.

Type: forged aluminum piston
Piston diameter: Ø 57.44 mm (bore 57.50 mm)
Oversize: +1.50 (letter 150)
Treatment: skirt with anti-friction treatment
Delivered with: ring(s), circlips, and pin

Designed to withstand the demands of off-road riding, this forged piston offers a uniform construction and tolerances suitable for restorations or preparations in +1.50 size. The skirt treatment aims to minimize wear and friction during warm-up and break-in phases, providing a more consistent engine performance during motocross sessions.

Main compatibilities: particularly suitable for YAMAHA YZ 125 (1980, 1981, 1982 - 125 cm3). Always check the dimensions and engine references before installation to ensure proper fit and correct bore size.
