Description
Regular oil changes are the lifeblood of your Hyosung, but years of road grime and overtightening can leave your drain cap looking worse for wear. A rounded bolt or a warped plate leads to weeping leaks and potential engine damage. This replacement set ensures your service goes smoothly with fresh, reliable hardware designed to handle the heat of the road.

📜 Model Fitment
Confirmed Matches: Fits GT250 and GT250R (Carburettor & EFi models) and GT125 and GT125R (Carburettor models) manufactured between 2003 and 2020.
This part will not fit the GV125S Bobber, GV250-DRA, GV300, or GV650 models due to completely different engine layout design variations.
This drain plate setup arrives with a standard non-magnetic bolt. While it does the job fine, upgrading to a coloured magnetic variant is highly recommended for trapping internal debris. Remember to get yourself these extra parts inside your shopping cart too! You will also need a fresh rubber O-ring to ensure a proper leak-free seal.
🔧 Oil Change Tips
- Warm it up: Ride gently for 5–10 minutes before draining. Warm oil flows much faster and carries away far more suspended engine contaminants.
- Check your O-Ring: Never reuse a flattened or crushed old sealing ring. Always inspect for small nicks or tears to prevent annoying driveway oil puddles.
- Don’t over-torque: The engine casing sump threads are very soft aluminum. Tighten the hardware until snug, but don’t force it—save your thread tracks from stripping!
