VERTEX offers top-engine piston kits designed for the complete rebuilding of high-performance 2-stroke engines. Each kit typically includes a high-strength aluminum piston, piston rings, pin, circlips, needle cage and a high-mount gasket kit to ensure a complete and reliable rebuild. Pistons are made from high-silicon alloys offering an excellent compromise between lightness, strength and thermal resistance. Their precision design improves combustion, reduces friction and optimizes piston stability at high rpm to guarantee consistent performance in extreme conditions. The skirt's anti-friction treatment improves running-in, reduces wear and increases engine longevity in intensive enduro or motocross use.
