CT70 Blackout Rear Disc Brake Conversion

Description

Transform your ride with the Bart Moto Co. Rear Disc Brake Conversion Kit, designed to fit all models of Honda CT70, Honda Dax, Ice Bear Champion, Rocky Amigo, and other compatible clone platforms.

This all-in-one system delivers serious stopping power, allowing you to confidently lock up the rear wheel when needed. Built for reliability and performance, the kit features a heavy-duty billet rear hub, a CNC-machined billet brake pedal assembly with a smooth needle-bearing pivot, and an integrated master cylinder brake switch.

At the heart of the system is a powerful 4-piston caliper paired with our high-mount billet caliper bracket, engineered for proper alignment and maximum braking efficiency.

The included hub uses a Z50 3-bolt wheel mounting pattern. If you are running CT70 wheels, our BMC CT70 Rim Adapter Plate is available as an add-on on this page.

You can also configure this kit into a complete rear hub and brake assembly using the available add-ons on this page, including the CT70 Rim Adapter Plate, Rim Adapter Hardware Kit, and 3-Bolt Rear Sprocket.

This conversion isn’t just an upgrade — it’s a must-have for riders pushing big motor builds and demanding modern braking performance from their CT70 platform.
