Upgrade the rear braking performance of your Yamaha YZ125 with the BRAKING BY4506 Batfly Rear Brake Rotor. Designed for 2002–2011 Yamaha YZ125 models, this high-performance replacement rotor uses directional Batfly geometry with a non-round profile to improve braking response, control, and modulation throughout the entire braking event.
Manufactured from laser-cut AISI 410 stainless steel, the BRAKING BY4506 rotor is heat treated and finished on CNC machines for precise fitment and dependable performance. Its specialized groove design promotes improved cooling by creating a ventilation channel between the brake pads and rotor. As the inner and outer pad surfaces alternately contact the disc, heat can dissipate more effectively, helping maintain consistent braking performance during demanding riding conditions.
The Batfly system also helps renew and clean the brake pad surface with each pass across the grooves. This maintains a more consistent friction coefficient and supports improved pad effectiveness, even in challenging environmental conditions. The result is stronger braking feel, enhanced modulation, and reliable rear-wheel control for motocross and off-road riding.
