Features

WÖSSNER Forged Piston - Ref. 8134DA

Forged piston designed by Wössner in Germany for cross and off-road applications. Made from high-quality aluminum, this oversized piston letter A is intended for modifications and replacements on cylinders bored to Ø 68.00 mm. Its skirt features an anti-friction treatment to reduce wear and facilitate the break-in process during the first start-up.

Piston diameter: Ø 67.94 mm
Recommended bore: 68.00 mm
Material: forged aluminum
Number of rings: 2
Delivered complete: rings, circlips, and pin

The forging process gives the piston a dense and homogeneous structure, suitable for the demands of cross engines. Supplied ready to install, it allows for a clean replacement after machining to size A without requiring additional machining. Ideal for modifications where durability and high RPM performance are desired.

Notable compatibility: YAMAHA YZ 250 (1989‑1991). Always check the dimensions and reference before installation to ensure proper clearance and correct displacement.
