FAQs
Do these discs come pre-oiled?
No, they arrive dry. You must soak them in clean, motorcycle-specific engine oil before installing them in your clutch basket.
How do I know if these fit my bike?
Verify that your current discs share the 91mm internal diameter and fall within the 110mm-119mm external diameter range, and cross-reference the part number 738.00.83 with your bike's service manual.
Why is the thickness important?
The 3mm thickness is critical for maintaining the correct stack height; if the total thickness of the clutch pack is incorrect, the clutch will either slip or drag.
Can I replace just one disc?
It is highly recommended to replace all four discs in the kit simultaneously to ensure even wear and consistent friction characteristics across the entire clutch pack.
What are MCC102 linings?
MCC102 is a proprietary friction material compound used by TRW that offers a balance between long service life and high-friction grip.
Troubleshooting
Clutch slipping under load
Verify that your clutch cable or hydraulic slave cylinder is not too tight; check if the discs were properly soaked in oil before installation.
Difficulty shifting gears
Ensure the stack height is correct and that the clutch basket fingers are not 'notched' or worn, which can prevent the discs from moving freely.
Pros and Cons

Setup, Compatibility & Care
Before installation, it is critical to soak the new clutch discs in the manufacturer-recommended engine oil for at least 30 minutes. This ensures the friction material is properly saturated, preventing premature scorching during the first ignition. Always check your motorcycle’s service manual to verify if your specific clutch assembly requires a 'stack height' check before finalizing the installation. To maintain the longevity of your clutch, ensure your clutch cable or hydraulic fluid system is properly adjusted or bled, as incorrect tension can cause unnecessary drag or slippage. Regular oil changes are essential to remove debris and maintain the friction properties of the MCC102 linings.
