MOOSE offers you Pro Race high-performance 4-stroke piston kits made from high-strength forged alloys with a reinforced "fully boxed" internal structure, offering an excellent compromise between lightness, strength and durability. Their optimized design reduces stress on the piston pin and enhances high-speed stability for greater engine reliability in extreme conditions. The full-radius dome promotes more efficient combustion while limiting the hot spots responsible for detonation, improving overall engine performance. The specific skirt coating reduces friction, heat and wear to increase engine longevity and performance in intensive motocross or enduro riding. Each kit typically includes high-performance piston, rings, DLC pin, circlips and top-end gaskets to ensure a complete, high-performance top-end rebuild.
