Product Description
Restore the essential safety link between your handlebar and taillight with the Genuine Royal Enfield Front Master Cylinder Switch Kit. This OEM component (Part No: 594710/A) is the primary sensor that activates your rear brake lamp whenever the front brake lever is squeezed.
Designed specifically for Unit Construction Engine (UCE) and early oil-cooled models equipped with front disc brakes, the 594710/A is a pressure-sensitive or mechanical micro-switch (depending on the master cylinder version) that mounts directly to the underside of the front master cylinder. It features a “plug-and-play” two-pin connector, allowing for a quick replacement without the need for wire stripping or soldering. As a genuine factory part, it is engineered to withstand high vibration and exposure to the elements, preventing the common failure where the brake light remains “always on” or fails to illuminate—a critical issue for road safety and vehicle inspections.
Key Features:
-
OEM Safety Compliance: Ensures your motorcycle remains street-legal by keeping the brake signaling system in sync with your braking input.
-
Direct Bolt-On Fit: Specifically molded to fit the contours of factory Royal Enfield master cylinders for a secure, rattle-free mounting.
-
Weather-Sealed Terminals: Constructed with protective boots or internal seals to prevent moisture from causing electrical shorts or corrosion.
-
Complete Kit: Typically includes the switch assembly and the small mounting screw required for installation.
-
Precision Activation: Calibrated for immediate response, signaling the vehicle behind you the moment you apply front brake pressure.
