Reproduction drilled front brake rotor for the CB450K/750. Made to exceed OEM specifications. If the stock rotor is worn out or warped now’s the time to install a brand new one! Whether it’s for a restoration or a daily rider this is a great part especially if you’re building a complete new wheel. Remember to use Loctite on the bolts that hold the rotor and torque them to spec, then adjust the bracket that holds the caliper. It’s a good idea to replace the pads at the same time.
We also carry a non-drilled version of this rotor and complete kits for replacing the front brake system.
