VERTEX offers you a piston kit designed for 125cc 2-stroke engines requiring responsiveness, power and endurance, with high-quality aluminum alloy construction offering excellent mechanical and thermal resistance to high revs and heavy motocross use. Thanks to its precision machining and anti-friction coating on the piston skirt, this kit reduces internal friction, improves lubrication and promotes more efficient combustion to maintain smooth revving, lively engine response and consistent performance. Its optimized design maintains stable compression, minimizes wear on internal components and ensures excellent durability even under extreme operating conditions. The complete ready-to-fit kit typically includes piston, rings, pin, circlips, top-engine seals and a needle cage to ensure a reliable, long-lasting top-engine rebuild.
