(Must be used with an 11mm Front Master Cylinder which comes stock on all the above models. A Ride Eng. Brake Hanger bracket is required to install on a stock size disc.)Description: Ride Eng.’s newest product is all about improving the braking performance of modern day dirt bikes. Our billet caliper achieves this with larger pistons, a solid, flex free body and with cooling fins that allow air to pass completely through. Although braking power is a little less than an over-sized rotor kit (we estimate a 15% vs. 20% with a 270mm rotor kit), its the feel and modulation on how it applies the pressure to the brake pads that’s really impressive here. Initially the lever feels softer, and with less effort the connection between your finger tips and the front tire is greatly improved. This relationship is so good, that it can be paired up with an over-sized rotor kit to give supercross style stopping power! The caliper is lighter than stock and its performance gains can be fully utilized by riders from novice to pro.
