Stainless Steel Crank Shaft Plug (Flywheel Stator Cover Cap) – Various Hyosung Models
Bin that “cheese-metal” OEM plug. This solid, weighted Stainless Steel replacement is significantly more robust than the flimsy stock part, providing a reliable, multi-tool access point you can trust during engine maintenance.
- ✅ Beefy Build: More material weight means it won’t strip or round off like the original.
- 🛠️ Multi-Tool Drive: Use a socket, hex bit, or large Allen key to turn the engine over with ease.
- ⚙️ CNC Stainless: Corrosion-proof, weather-resistant, and less likely to seize than the stock cap.
- 📦 What’s Included: 1x Heavy-Duty Crank Plug + Fresh O-Ring Seal.
Description
Every mechanic in the UK and EU knows the struggle with the stock Hyosung crank plug: it’s made from a soft material with an awkward single “slit” that rounds off easily when seized. This unique creation is a serious performance upgrade. Our own testing proved that the added weight and superior material prevent the common issues, making your life on the road and maintenance schedule much simpler.
💎 The Visual & Performance Upgrade That Lasts
We solved the common “stuck plug” nightmare using solid stainless steel and superior CNC machining.
| Corrosion Free Salt-resistant for harsh winter riding conditions. |
Robust Design More ‘meat’ around the tool opening; won’t strip. |
| Easy Access Use common workshop tools instead of a mystery key. |
CNC Precision Perfect thread fitment every time. |
