EBG Front Brake Kit

Most of these bikes leave the factory with a thin, undersized front rotor on a machine that will do 70 km/h. The EBG Front Brake Kit replaces it with a 240 or 250 mm floating rotor at 3.5 mm, a genuine Sur-Ron Ultra Bee caliper and master cylinder, and a steel-braided line — the front brake the bike should have shipped with.

Stock front brake vs EBG Front Brake Kit

Nearly double the disc material means far more heat absorbed before the lever goes long — that is where fade comes from, not lever effort.

Key specs

Which option?

The complete front kit — genuine Ultra Bee caliper and master cylinder, floating rotor, radial CNC bracket, rotor guard and steel-braided line. Pick your bike and model; per-bike rotor size and bracket are matched for you. Bracket colour options and standalone parts are on the separate rotor-guard and bracket listings.

Fits

Uses the factory mounting points — no drilling, no adapters. Some forks need 0.5–1.5 mm shim washers behind the caliper for dead-centre alignment. Fitment is fork-dependent on some models; add a note to your quote and we will confirm the bracket before it ships.

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. Bleed the line 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.
