What comes in the MOTO1988 starter relay kit and why each part matters?

The kit supplies the essential components for replacing a failed relay and protecting the new unit from overcurrent. Having the correct plug and fasteners simplifies installation and avoids hunting for missing hardware.

• 1x 30A M-B square plug starter relay — the main switching device
• 1x relay plug — matches the factory connector for a clean replacement
• 2x bolts — secure the relay in the original mounting location
• 2x 30A blade fuses — provide immediate protection and spare fuse

How easy is installation and what should I check before replacing the relay?

Installation is typically a straightforward plug-and-bolt swap for owners comfortable with basic motorcycle electrical work. Always disconnect the battery first and compare the kit’s plug shape and OEM numbers with your existing relay before proceeding.

• Disconnect battery negative before starting the job
• Compare part shape, pin layout and OEM numbers listed on the product page
• Use supplied bolts and fuses; torque to manufacturer specs if available
• Test starter operation before reassembling fairings or panels

Are there any tips to avoid buying the wrong relay?

Confirm fitment using your motorcycle’s year, model and current relay part number. Visual checks and the OEM numbers listed with this kit are the best ways to ensure compatibility.

• Match your existing relay’s connector style (M-B square plug) to the kit
• Verify at least one of the manufacturer part numbers provided matches your OEM part
• Review images and the model compatibility list for your exact year
• Contact seller support for confirmation if uncertain; one-year product service available
