NEWFREN DF5079A brake disc. NEWFREN discs are made from carbon steel that is given a special heat treatment. Depending on the type of disc, a die or a special laser cut is used to make it. Great care goes into the finish of the product to ensure the disc is perfectly parallel to the wheel centre within the tightest possible tolerances, so that the wheel runs perfectly true. The result is controlled, progressive braking. For perfect results we recommend using NEWFREN sintered or organic pads. The standard discs are ideal for replacing the genuine fitted disc. They are usually rear discs, but they are also used at the front on motorcycles from earlier years in particular. NEWFREN offers a complete range for demanding front and rear use.
