Designed for engine tuning and off-road use, the PROX Titanium Exhaust Valve offers the sought-after balance between strength and lightness. Forged from a single piece of titanium, it reduces the moving mass of the valvetrain for lower inertia and a more responsive valve system. Its plasma coating enhances thermal resistance at the seat and contributes to improved longevity at high RPMs.
Intended for riders who work on the cylinder head and valvetrain, this valve is suitable for the typical 350 displacements of modern motocross. Compatibility examples: KTM 350 SX-F (2025), HUSQVARNA FC 350 (2025), GAS GAS MC 350 F (2024). Be sure to check the original part number and tolerances before installation (guides, seats, clearances) to ensure a safe and durable implementation.
