Description

A failing starter solenoid is one of the most common reasons for a non-starting Hyosung. Over thousands of heat cycles, the internal copper contacts burn out or stick. Replacing this unit is essential maintenance for life on the road. We’ve sourced this specific aftermarket unit because it matches the factory plug, ensuring your bike’s electrical integrity remains intact without risky modifications.
