Product Description
Secure your fuel and maintain the classic look of your tank with the Genuine Royal Enfield Fuel Tank Cap Assembly. This OEM locking cap (Part No: 597128) is the standard replacement for Unit Construction Engine (UCE) models that utilize a traditional twist-and-lock filler neck rather than the flush-mount “Classic” style.
The 597128 assembly is crafted from high-durability, chrome-finished metal to resist corrosion and fuel-vapor degradation. It features a precision-engineered internal locking mechanism and comes with a dedicated key to prevent fuel theft and tampering. The underside is equipped with a high-grade rubber gasket that ensures a vapor-tight seal, preventing fuel leakage during rides and minimizing the evaporation of gasoline when the bike is parked. As a genuine factory part, it offers the perfect fitment required to avoid the common rattling or “seepage” issues often associated with generic aftermarket fuel caps.
Key Features:
-
OEM Locking Security: Includes a matching key to keep your fuel tank secure against unauthorized access.
-
Weatherproof Chrome Finish: High-quality plating designed to maintain its shine despite exposure to the elements and gasoline spills.
-
Airtight Sealing: Features a factory-spec gasket to ensure no fuel leaks onto your paintwork or evaporates over time.
-
Direct-Fit Installation: Simply twist into the tank filler neck and lock; no modifications to the tank are required.
-
Vintage & UCE Heritage: Matches the aesthetic of the traditional Bullet and Electra fuel tanks.
