Custom rear hydraulic with regen / electronic brake pedal for Sur Ron. Hydraulic master cylinder activates rear brake (replacing hand-operated master cylinder) and position sensor can control motor regen or ASI BAC or Sin-Tech motor controllers (not compatible with stock Sur-Ron motor controller).  Due to clearance issues, the front-most peg position is not available.

Bike Requirements

- Master cylinder uses only dot4/dot5.1 brake fluid and is incompatible with brakes that use mineral oil such as stock brakes. We recommend Hope Tech V4 calipers. Included with the kit is 10mm to 6x1.0mm female banjo fitting for connection hydraulic brake line.

- Regen function requires an aftermarket motor controller with analog regen input.  Please check with the company that provided the upgrade kit for compatibility.  The output connector is 3 pins female Higo connector (same as Bafang 3 pin throttle). Please contact us for the other connector options.
