Product Description
Restore your engine’s compression and power with the Royal Enfield Inlet Valve (574144/C). Manufactured from high-grade, heat-resistant steel alloy, this valve is built to withstand the extreme thermal cycles and high-pressure environment of the Himalayan’s combustion chamber.
The valve stem and head are precision-ground to ensure a perfect seal against the valve seat, preventing pressure loss and ensuring consistent idling and throttle response. As a genuine OEM part, it matches the exact weight and metallurgical specifications required to maintain the engine’s balance and longevity.

-
Precision Seating: Engineered for a gas-tight seal to maintain optimum cylinder compression.
