Offers excellent resistance to high mechanical loads thanks to a high-performance forged racing design, specially developed for 4-stroke motocross engines.
MOOSE offers you high-performance Pro Race 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 improves stability at high rpm and reduces stress on the piston pin to guarantee enhanced engine reliability. The full-radius dome promotes more efficient combustion while limiting the hot spots responsible for detonation, improving overall engine performance. Low-friction skirt coating reduces wear, heat and mechanical losses for longer life in extreme conditions. Each kit typically includes piston, rings, DLC pin, circlips and top engine gaskets to ensure a complete, high-performance engine rebuild.
