Description
Over time, the constant rotation, heat, and pressure can wear down the front sprocket shaft seals, leading to a steady weep of engine oil. If you have an older Hyosung 125 or 250, replacing these soft seals is a non-negotiable safety upgrade. This kit is designed to provide an oil-tight seal, protecting your engine’s performance and, crucially, keeping your rear tyre clean and safe from dangerous oil residue.

Use this kit to resolve those stubborn leaks and regain full confidence in your machine.
| Stop Oil Splatter Keeps your engine casing and swingarm clean. |
Safety Assurance Prevents hazardous oil fling onto your rear tire. |

🔧 Install Tips
- Sprocket Alignment: Ensure the raised “hump” of your front sprocket faces OUTWARDS (away from the engine) when refitting.
- Clean the Area: Thoroughly clean the shaft and casing area before installing new seals to ensure a perfect fit.
- Gently Does It: Use a flat tool to gently lever out the old seals, taking care not to scratch the soft aluminium engine casing.
