Description
When you’re pushing a KX250F to its limits, your factory piston won’t cut it. This Wossner kit replaces worn or damaged pistons with a precision-engineered assembly that handles sustained high RPM loads and heat stress without compromise. Complete with rings, pin, and clips, it’s a bolt-in solution that restores—or exceeds—OEM performance.
Wossner engineered this piston using finite element analysis to optimize ring lands, skirt geometry, and load distribution. The 4032 T6 forged aluminum provides the strength-to-weight ratio serious racers demand, while the permanent skirt coating reduces friction and piston rock for quieter, more efficient combustion. Whether you’re rebuilding after a seizure or upgrading for a top-end refresh, this kit delivers the reliability and performance you expect from a premium manufacturer.
