Starter Motor Solenoid Relay – Hyosung GV125 GV125S GV250 GV300S

Description

🛠 Starter Motor Solenoid Relay – Hyosung GV125 / GV125S / GV250 / GV300S

The starter solenoid relay is a critical part of the starting system on your Hyosung, and a very common replacement item. Like most motorcycles, these relays eventually wear out or fail — often causing strange behaviour when you try to start your bike.

We supply a quality aftermarket version compatible with many Hyosung cruisers, including GV125 (carb & EFI), GV125S, GV250, and the latest GV300S Bobber.
Please check the list below to confirm fitment for your model.
