VERTEX offers you a high-performance piston kit designed for large-displacement 2-stroke engines, with high-quality cast aluminum construction offering an excellent compromise between lightness, strength and thermal resistance. Precision machining and a molybdenum disulfide coating on the piston skirt reduce internal friction, improve lubrication and promote faster running-in, while extending engine life. Designed to withstand the high temperatures and extreme stresses of motocross and enduro riding, this kit ensures optimized combustion, stable compression and smooth, powerful revving. The complete ready-to-fit kit includes piston, rings, pin and circlips for a reliable, long-lasting top-end rebuild.
