Product Description
The 594402 Inner Tube Kit is a factory-spec replacement designed for riders experiencing fork bends, pitting, or deep scratches that lead to persistent oil seal failure. Unlike aftermarket alternatives, this genuine Royal Enfield pipe is manufactured using high-grade steel with precise wall thickness to handle the heavy front-end load of 350cc to 650cc motorcycles.
Each tube features a superior hard-chrome finish that provides a mirror-smooth surface. This reduces friction against the oil seals and bushings, ensuring a plush ride and preventing oil leaks. The “Fork Pipe Spining” process used in manufacturing guarantees perfect circularity and straightness, which is critical for maintaining high-speed stability and preventing “speed wobbles.”
Key Features:
-
Factory Precision: Genuine Royal Enfield spare ensures 100% compatibility with the OE outer sliders and internal damping components.
-
Hard-Chrome Surface: Ultra-smooth plating extends the life of your oil seals and resists corrosion and road salt.
-
Enhanced Stability: Corrects steering “heaviness” or pulling caused by slightly bent or misaligned old pipes.
-
Heavy-Duty Build: Optimized for the weight and performance demands of the Twin-cylinder 650cc and single-cylinder cruiser platforms.
-
Cost-Effective Repair: Allows you to rebuild your existing shocker assembly without the expense of a full leg replacement.
