Wossner Piston Kit for KTM 65 SX 2009-2025 8241DA

If you're running a KTM 65 SX and serious about consistent power delivery across repeated heat cycles, a quality piston kit is non-negotiable. The Wossner 8241DA replaces worn pistons that cause compression loss, increased blowby, and unpredictable throttle response—issues that compound quickly in 2-stroke engines. This complete kit gets you back to baseline performance with German engineering designed specifically for the demands of modern small-displacement racing.

Built from 4032 T6 forged aluminum, the piston resists thermal stress and maintains tight tolerances lap after lap. The permanent skirt coating cuts friction and piston rock, translating directly to quieter operation and more efficient power transfer to the crankshaft. Every component—piston, rings, pin, and clips—arrives ready to install, saving you the headache of sourcing matched parts.
