BRAKING BY4501 Batfly Rear Brake Rotor

The BRAKING BY4501 Batfly Rear Brake Rotor features directional Batfly geometry with a non-round profile. Its laser-cut AISI410 stainless steel construction is heat treated and finished on CNC machines for precise manufacturing and consistent performance.

The Batfly system is designed to improve brake response and modulability, helping enhance rider feel throughout the braking event. Special rotor grooves support improved heat dissipation by creating a ventilation channel between the brake pad and disc surfaces, allowing heat generated on one side to dissipate while the opposite pad is not contacting the disc.

The grooved design also helps clean and renew the pad surface with each pass, supporting a consistent friction coefficient even in demanding environmental conditions. This rear rotor fits select 2004–2012 Honda CRF450R models and the 2017 Honda CRF450RX.
