Frequently Asked Questions
What size are these rotor bolts?
M6 x 23mm countersunk (CST) bolts spec'd for Yamaha YZ/WR brake rotor mounting and matching Warp 9 rotors.
Why are Yamaha bolts longer?
Yamaha rotor carriers use a deeper mount, so the 23mm length reaches full thread engagement. Match the length and head to your rotor.
Should I use thread locker?
Yes. Medium-strength thread locker plus correct torque keeps the disc secure through repeated heat cycles and trail vibration.
