Overall the braking system works well but there are some aspects which can be safely improved to enhance performance and tailor controls to the rider. These are outlined below.
The brake is prone to overheating and brake fade in difficult terrain. After inspection of brake fluid and components brake professionals advised it is a result of the combination of low fluid volume and attachment of the steel brake hose to the rear of the engine.
The standard fluid line is very difficult to work on and remove due to the location and mounting of the junction between the rubber and steel brake lines behind the engine.
The solution is a larger reservoir coupled with a single piece braided stainless steel brake line between the caliper and the master cylinder. With this modification the fluid stays clear and brake fade is eliminated. A single piece line needs to be between 1.0 and 1.1 metres in length without the fittings, any excess in length loops up in front of the fuel tank.
