WÖSSNER forged piston designed for modifications and replacements on motocross engines. Manufactured in Germany by a specialist in engine parts, this forged aluminum piston is machined for demanding applications where load-bearing capacity and bore accuracy are critical.

• Piston diameter: Ø 66.340 mm (bore 66.40 mm) — oversize letter: A
• Material: forged aluminum
• Number of rings: 2 (rings included)
• Anti-friction treated skirt to reduce wear during operation
• Delivered complete: rings, circlips, and pin
• Category: Cross — designed for the specific stresses of off-road use

This piston is aimed at riders looking for a precisely machined engine part for replacement or refurbishment. The forging process gives the body a compact and homogeneous structure, suitable for the severe engine cycles encountered in enduro and motocross. The treated skirt minimizes friction during break-in and contributes to better longevity of the support tolerances in the cylinder.

Common compatibility: HUSQVARNA WR 250 (2012-2013), HUSQVARNA CR 250 (2004). Check the reference and dimensions before installation.
