Description
If your 650cc Hyosung is showing signs of clutch slip or juddering under load, it’s time for an upgrade. We only source our heavy-duty friction plates from reputable brands like EBC or TRW Lucas, designed for road riders who need reliability. These plates are heat-treated for longevity and offer improved clutch bite compared to the factory originals, making them ideal for both stock and mildly tuned V-twin engines.

🔧 Install Tips
- Pre-Soak Overnight: You *must* soak the new friction plates in fresh engine oil overnight before installation. This is critical for longevity and performance.
- Check Steel Plates: Inspect your existing steel plates for warping or excessive wear. If they are damaged, they must be replaced (not included in this kit).
- Cable Adjustment: A major cause of premature clutch failure is incorrect clutch cable slack. Follow your service manual exactly for correct cable adjustment.
Thanks to Matt T. for sending us this quick little video of the clutch install! Remember though, the smaller plate goes in first!
