DirtyBike CNC Rear Brake Disc Guard | Sur-Ron Ultra Bee

Protect the rear brake rotor on your Sur-Ron Ultra Bee from rocks, sticks and trail debris with the DirtyBike CNC Aluminum Rear Brake Disc Guard. Positioned around the vulnerable lower portion of the rotor, this guard helps deflect impacts before they can bend the disc or damage the rear braking system.

A rear disc guard is a practical upgrade for technical riding, especially on rocky trails, in deep ruts or around fallen branches. Protecting the rotor helps preserve consistent braking performance and can prevent an impact from ending the ride early.

CNC-Machined Protection

The guard is CNC machined from billet 6061-T6 aluminum, providing a strong structure without adding unnecessary weight. Corrosion-resistant 304 stainless steel screws are included, along with an integrated wheel speed sensor mount that keeps the factory sensor properly supported.

A durable hard-anodized finish adds surface protection and is available in three color options, making it easy to coordinate the guard with the rest of your Ultra Bee build.
