Description

If you're running a KTM 125 SX at the track or trail, piston wear is inevitable—and a worn piston kills both power and reliability. The Wössner 8056DA replaces worn internals with German-engineered precision, restoring compression and responsiveness while the permanent skirt coating reduces friction losses. This is the OEM-quality replacement that gets your 2-stroke back to factory performance standards.

Built from 4032 T6 forged aluminum and refined through FEA analysis, this complete kit includes everything needed for a straightforward top-end refresh: piston, rings, wrist pin, and circlips. The T6 heat treatment ensures durability under sustained high-load riding, while the advanced skirt coating keeps combustion temperatures in check and engine noise down. Bolt-on installation—no machine work required.

Helps keep cool, works great!
