Description
If you’re running a KX125 at the edge of the powerband, factory pistons won’t cut it—Wiseco’s forged design delivers the strength and compression stability needed for consistent performance across competitive sessions. The complete kit eliminates the hassle of sourcing individual components, and the E-coated crown resists micro-welding that degrades power over time. You get measurable gains in horsepower and torque without sacrificing longevity.
