• Optimized cooling circuit design to increase liquid volume and improve thermal dissipation.
• High-performance exhaust valves and bronze cylinder head dome for mechanical durability.
• Forged piston with skirts treated with molybdenum disulfide to reduce friction and wear.
• Delivered complete: piston, rings, circlips, pin, gasket set, and, depending on variants, cylinder head and exhaust valves.
