BRAKING Epta Batfly Kit Aluminum Hub 280mm for Yamaha YZ250FX & YZ125 Models

The BRAKING Epta Batfly Kit Al Hub 280mm is an innovative upgrade designed to enhance your Yamaha YZ250FX and YZ125 series motorcycles. Building upon the success of the original Batfly system, this evolution features a newly developed rotor-hub coupling that delivers improved performance, more consistent braking feel, and greater durability. Crafted with high-quality materials, this kit ensures that your bike maintains peak braking efficiency during intense riding sessions and competitive events.

One of the standout features of this system is the use of an aluminum AL7075-T6 carrier, which offers an optimized shape for reduced weight and increased rigidity. The same distinctive Batfly geometry with a directional "non-round profile" ensures superior aerodynamics and heat dissipation, contributing to more homogeneous rotor temperatures during prolonged braking. The innovative rotor-hub coupling system is designed for direct contact between components, providing riders with a powerful and responsive braking sensation from initial engagement to full stop. This direct contact minimizes energy loss and enhances overall brake efficiency, which is especially beneficial in high-performance scenarios such as MXGP racing.

The system also improves load transfer between the rotor and hub thanks to redesigned connecting components, including clips and nails that prevent deformation and floating variability over time. Additionally, the rotor stems are engineered with a radial sliding feature that responds effectively to stress and deformation caused by high temperatures, maintaining consistent braking performance. This design results in better heat management, preventing hot spots and ensuring a more even temperature distribution across the disc. Riders can expect enhanced control, confidence, and braking power with this advanced setup, making it a preferred choice for professional and serious amateur racers alike.
