Follow the vehicle manufacturer’s recommended torque settings, typically ranging from 30 to 45 Nm for most sportbike disc rotors. Refer to your service manual for exact values.
Are the Fuji locking nuts reusable?
Fuji locking nuts are designed for repeated use. Ensure they are clean and free of debris before re‑installation to maintain their locking effectiveness.
Will these bolts fit my specific bike model?
The kit is engineered to match OEM specifications for a wide range of motorcycles. Verify the bolt pattern and thread pitch in your bike’s service guide to confirm compatibility.
How does the class 10.9 steel improve performance?
Class 10.9 steel offers a higher tensile strength than standard grades, providing superior resistance to stretching and shearing forces, which translates to more reliable braking under aggressive riding conditions.
