    Product Description


    Replacement Regulator Rectifier For Sinnis RSX Terrain & Lexmoto Enigma 125

    If you're experiencing issues with the electrical system on your motorcycle then it could be down to the regulator rectifier. This part is built to meet original OEM specification with higher grade electrical components and better cooling which results in higher efficiency.

    Common Issues

    • Battery drain - Burnt out diodes within your regulator can lead to a drop in voltage output from your regulator. Symptoms include poor starting, dimming lights & irregular meter readings which can lead to eventual failure to start.
    • Battery overcharge - Caused by the regulator failing to bring the voltage output from the stator down to the correct level. The higher voltage greatly shortens the life expectancy of the battery and can cause bulbs to blow at random times or damage other electrical components within the system.

    Key Features

    • Manufactured to meet OEM specification
    • Universal adaptation to fit many different models
    • Plug and play
    • High grade electrical components for improved efficiency
