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 everyday roads. We’ve sourced this specific aftermarket version because it matches the factory plug, ensuring your bike’s electrical integrity remains intact without risky modifications.

📜 Starting Troubleshooting Guide
| Symptom | Likely Cause |
|---|---|
| Continuous “Clicking” noise | Internal solenoid coil is failing to hold positive mechanical connection. |
| One “Click” but no rotation | Heavy internal copper contact points are completely burnt out or broken. |
| Starter keeps spinning after button release | Excess amp draw heat has caused the contacts to weld completely shut. |
📜 Model Fitment
Confirmed Matches: Fits the following twin-cylinder models:
- GT125R / GT125RC: All carburetted and fuel-injected (EFi) production models (2003–2020).
- GT125 Naked: All naked Comet and P variants (2003–2020).
- GT250 / GT250R / GT250RC: All carburetted and fuel-injected variations (2003–2020).
Persistent ignition starting dropouts are frequently paired with a weak battery dropping voltage under load. Ensure your heavy frame connection terminals are perfectly clean, and treat the wire lugs to protect your electrical links against moisture.
🔧 Install Tips
- Safety First: Always disconnect your motorcycle battery’s negative earthing terminal completely before unbolting the heavy gauge copper power feeds to prevent accidental shorts or sparks.
- Direct Swap: Simply slide the small safety signal block free from the main harness plug, unbolt the twin post nuts holding the heavy starter leads, and drop the fresh housing right into the factory frame boot slot.
If you want to verify your handle start button circuit path or need advice on tracking down a hidden fuse link block under the battery tray, drop us an email. For circuit diagrams, diagnostic steps, or technical guides like our DIY Clutch Guide, head to the forums.
