The PROX steel intake valve (ref. 28.2418-3) is a spare part designed for Yamaha Cross machines equipped with original or compatible camshafts and cylinder heads. Designed for intake, it plays a crucial role in the distribution system to ensure sealing and the passage of gases to the combustion chamber. Its steel construction provides the necessary robustness to withstand the high stresses encountered in motocross.
Ideal for restoring a worn cylinder head or during an engine rebuild, this PROX intake valve is aimed at riders who want to replace a damaged valve with a solid and easy-to-install part. During maintenance, be sure to check the valve seat, stem, and operating clearance to ensure optimal functioning of the intake system.
