WÖSSNER forged piston designed for motocross competition and engine rebuilding. Made in Germany by a specialist in engine parts for 2 and 4-stroke engines, this piston combines materials and finishes suited to the demands of motocross displacements.

• Manufacturer reference: 8021DA
• Piston diameter: Ø 66.340 mm (bore 66.40 mm)
• Oversize: Letter A
• Material: Forged aluminum
• Number of rings: 2 (supplied with rings, circlips, and pin)
• Finish: Anti-friction treatment of the skirt to limit friction during heating

The forged construction provides the piston with superior mechanical strength compared to cast pistons, making it suitable for the high stresses encountered in off-road conditions. Its treated skirt limits wear and assists with initial break-in during track sessions or intense enduro outings.

Notable compatibility: HONDA CR 250 R (ME03) 1994–1996 (250 cm³). Before installation, check the bore and adhere to manufacturer tolerances. An ideal part for engine refurbishment or serious preparation, this WÖSSNER piston is aimed at demanding riders seeking a quality part for their motocross.
