Product Information
Full details
The EBC CK5668 clutch disc kit is designed for motorcycle owners seeking a reliable, high-performance replacement that meets or exceeds original equipment (OE) specifications. Ideal for riders who prioritize consistent power transfer and long-term durability, the kit uses advanced materials to prevent slippage during intense use. A notable caveat for buyers is that this kit contains friction discs only, meaning you may need to source separate steel drive plates or springs depending on the condition of your existing clutch basket assembly.

FAQs
Does this kit come with steel plates?
No, the CK5668 kit consists of the friction discs only.
Do I need to soak the discs before installing?
Yes, it is highly recommended to soak the friction plates in fresh engine oil to prevent glazing and burning the new material during the initial break-in.
Is this a performance upgrade or a stock replacement?
It functions as a high-quality OE replacement that offers improved heat resistance and durability over standard stock discs.
How do I know if I need new clutch springs?
Measure your current springs against the service limit in your motorcycle manual. If they are shorter than the specification, they will not provide enough pressure, regardless of how good your new discs are.
Will these fit my specific bike?
The CK5668 is a specific part number. Always cross-reference your bike's make, model, and year against the EBC fitment chart to confirm compatibility.
Troubleshooting
Clutch feels like it is slipping immediately after install
Ensure you have not used synthetic oils with friction modifiers, as these can cause clutch slip. Verify your clutch cable free-play is adjusted correctly.
Difficulty shifting gears
Check that the new plates were soaked in oil prior to installation and verify that the clutch basket is not notched, preventing plates from moving freely.

Setup, Compatibility & Care
Installation of the CK5668 kit should follow your specific motorcycle service manual guidelines. Because friction discs are porous, it is standard practice to soak the new plates in the recommended engine oil for at least 30 minutes before installation to ensure they are fully saturated, which prevents burning the material on the first ride.
Before installing, inspect your clutch basket for notches or 'grooving' on the fingers, as this will cause premature wear on any new disc set. Always replace your clutch springs if they are near or at their service limit to ensure the plates maintain proper clamping pressure.
