Product Description


Replacement Starter Relay

If you're experiencing issues with the starting system on your motorcycle then it could be down to the starter relay. This replacement part is built to meet original OEM specification with high-grade electrical components. Below is a list of common starting issues you may experience with a faulty starter relay:

Common Issues

  • Non-Start - Caused by failed circuitry within the relay itself. When trying to start the vehicle it will be completely unresponsive. If your vehicle has a kick start mechanism this will still function and allow the vehicle to start. 
  • Intermittent Start - If you occasionally find that your bike is unresponsive when attempting to start there may be an issue with your starter relay.
  • Relay Stuck On- Caused by the main contacts becoming stuck together. After the vehicle has started and is running it will continue to attempt to 'start'. If this happens, cut the engine immediately! As the engine is already running at this point, components in the starting system start working against each other and this can cause major damage.
  • Clicking Sound - If you hear a clicking sound when attempting to start the vehicle then your starter relay is most likely at fault.

Key Features

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


  • Cable length: 155mm
