EBG Rear Brake Kit V2

Built for how these bikes actually get ridden — the rear brake dragged through ruts, locked up on descents and cooked on long fire roads. A complete rear circuit built around genuine Sur-Ron Ultra Bee parts, bolted to the factory mounts with no fabrication.

Stock rear brake vs EBG Rear Brake Kit V2

More steel in the disc means more heat absorbed before the lever goes long — that is where fade comes from, not lever effort.

Key specs

Which option?

Every kit is complete — caliper, master cylinder, pads, steel-braided line, floating rotor, CNC bracket and rear rotor guard. Two things to choose:

• Rotor size — 220 mm suits most rear setups; choose 230 mm for a larger disc and extra bite where you have the clearance.
• Bracket colour — black, blue, galaxy purple, raw silver or red. Anodised finish, purely cosmetic.

Fits

Uses the factory mounting points — no drilling, no adapters. Some frames need 0.5–1.5 mm shim washers behind the caliper for dead-centre alignment; they are cheap and easy to fit.

Why riders swap it

Fade is heat, not effort. A 3.5 mm floating disc holds far more heat than a thin stock rotor before the lever goes long, and the floating carrier lets it expand without warping. The genuine Ultra Bee caliper and master cylinder give a firm, consistent lever — the same parts Sur-Ron fits to its own bikes, not the copies flooding the market.

Installation: bolts to the factory mounting points — no drilling, no adapters. Bleed the system after fitting; per-model setup videos are available on request.

Keep pads and rotor free from chain lube and brake fluid — contamination causes noise and is not covered by warranty.
