Features

WÖSSNER Forged Piston - Manufacturer Ref: 8134DB

Designed for Cross competition and demanding engines, this Wössner forged piston is made in Germany by engine part specialists. Crafted from forged aluminum and precisely machined, it features an anti-friction treatment on the skirt to reduce friction and improve fit in the cylinder.

Type: forged piston
Material: aluminum
Piston diameter: Ø 67.95 mm
Bore diameter: 68.01 mm
Oversize letter: B
Number of rings: 2
Delivered with: rings, circlips, and pin

This piston is intended for modifications and replacements on 2 and 4-stroke engines used in off-road applications. The oversize B corresponds to a piston diameter suitable for a slightly oversized bore to restore the correct clearance after reboring. Installation and break-in should follow the manufacturer's recommendations or those of a qualified workshop.

Common compatibilities: YAMAHA YZ 250 (1989, 1990, 1991 - 250 cm3). Always check the engine reference before ordering to confirm compatibility.
