Product Description
The 592237/A Rotor Assembly is a high-precision component that sits inside the left-hand engine cover. It interacts with the stator coil to generate the electrical power needed to charge the battery and run the motorcycle’s electronics. More importantly, it features the integrated “trigger” nodes that tell the Pulsar Coil exactly when to fire the spark plug.
Over time, rotors can lose their magnetic strength or the internal keyway can wear out, leading to erratic ignition timing, difficult starting, or high-RPM misfires. Replacing an aged or damaged flywheel with this genuine RE part restores factory-spec timing and ensures your charging system maintains a stable output, even under the heavy vibration of the 350cc thumper.
Key Features:
-
Genuine OEM Precision: 100% original Royal Enfield spare (PN: 592237/A) ensuring perfect balance and magnetic alignment.
-
Ignition Stability: Correct reluctor/trigger configuration provides accurate timing for the TCI (Transistorised Coil Ignition) system.
-
Heavy-Duty Construction: Built with high-grade steel and industrial-strength magnets to withstand extreme engine heat and centrifugal forces.
-
Optimal Charging: Provides the exact magnetic flux required for the factory stator to maintain a healthy 14V+ charging circuit.
-
Vibration Dampened: Engineered to precise tolerances to prevent engine crankshaft vibrations and bearing wear.
-
Direct Bolt-On: Features the standard taper and keyway for a secure fit onto the crankshaft.
