Improves power, engine responsiveness and reliability while reducing friction and thermal stress in intensive motocross or competition use.
MOOSE offers you high-performance 4-stroke racing pistons 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 enhances high-speed stability and reduces stress on the piston pin to ensure 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 (Diamond-Like Carbon) pin and circlips to ensure a complete, high-performance top-end rebuild.
