Description
If you’re running a KX 85 in competitive or trail racing, piston durability and horsepower output directly impact your results. Wiseco’s forged high-silicon aluminum construction withstands the extreme pressures of two-stroke racing while the optimized compression ratio delivers measurable power gains. This complete kit eliminates sourcing individual components and gets you trackside faster.
The E-coated crown, ring grooves, and pin bore resist wear better than standard pistons, meaning longer service intervals between rebuilds—a real advantage when you’re logging serious race hours. Less exterior machining improves bore sealing and compression consistency, translating to reliable performance lap after lap.
