It is a flat, circular metal disc attached to the wheel. When you apply the brakes, the brake pads clamp onto the brake disc, creating friction that slows down and eventually stops your ZX-12R 1200 Ninja. This process is essential for controlling your Kawasaki's speed and ensuring your safety on the road.\n\n Function of a Brake Disc on ZX-12R 1200 Ninja\n\nThe primary function of the brake disc .
