Description

If you're running a Polaris Sportsman 800 hard, factory pistons won't cut it. The Wossner K8877D200-2 delivers the durability and precision needed for sustained high-RPM performance, with a friction-reducing skirt coating that keeps temperatures in check and power delivery consistent. This is a complete bolt-in solution engineered for riders who demand reliability without compromise.

Why Choose Wossner: German engineering meets proven track performance. Every piston in this kit is forged to exact specifications using FEA modeling, then T6 heat-treated to handle the stress of aggressive riding. The permanent skirt coating reduces friction and piston rock—meaning less wear, more efficiency, and quieter operation.
