MOOSE offers you Pro Race high-performance 4-stroke piston kits made from high-strength forged alloys with a reinforced "fully boxed" internal structure to provide an excellent compromise between lightness, strength and durability. Their optimized design reduces stress on the piston pin and enhances the controlled flexibility of the assembly to increase reliability at high revs. The full-radius dome improves combustion while limiting the hot spots responsible for detonation, while the specific skirt coating reduces friction, heat and wear to improve engine longevity and performance in extreme conditions. Each kit typically includes high-performance piston, rings, DLC (Diamond-Like Carbon) pin, circlips and top engine seals to ensure a complete and reliable rebuild. Their racing design guarantees faster rev-up, better throttle response and excellent durability for intensive motocross or enduro use.
