Manufacturer Reference: 8012DA
WÖSSNER forged piston designed for motocross. Made in Germany by a specialist in engine parts, this aluminum piston features a forged construction to provide a dense and homogeneous structure, suitable for the demands of off-road use. The skirt receives an anti-friction treatment to reduce friction during high RPMs and improve the contact performance between the cylinder and the ring.
- Type: forged piston
- Piston diameter: Ø 71.93 mm (bore 72.00 mm) — Oversize letter: A
- Material: aluminum
- Number of rings: 2 (delivered with rings, circlips, and pin)
- Usage: motocross / off-road — compatible with listed KTM 300 models (years 1992–1994)
Delivered complete (rings, circlips, and pin), this piston allows for engine refurbishment during a +0.25 mm re-bore (letter A). Ideal for engine servicing on the mentioned 300 cm3 displacements, it fits into preparations where the reliability of thermomechanical parts is crucial. Follow the bore tolerances and assembly recommendations from the manufacturer during installation to ensure proper break-in and longevity of the piston-cylinder assembly.
