Advanced 270mm Batfly EPTA Front Brake Disc

The BY4128E Front 270 Batfly EPTA is a cutting-edge braking solution designed for ultimate performance and durability. Crafted with precision, this disc features a unique BATFLY geometry, characterized by its directional "non-round profile." Made from high-quality ALUMINUM AL7075-T6, the carrier optimizes the shape, reduces weight, and increases rigidity, resulting in a new style that stands out in the market. This innovative design ensures that riders experience enhanced braking performance with improved handling and control.
  • Optimized Shape: The Batfly geometry provides an optimized shape that reduces weight and enhances braking efficiency.
  • Aluminum Construction: ALUMINUM AL7075-T6 material ensures superior strength and durability.

Technical Advancements and Performance Benefits

The BY4128E Front 270 Batfly EPTA boasts an improved rotor to hub load transfer system. This system replaces the traditional hub-rotor coupling with new connecting components, clips, and nails, eliminating deformation and floating variability throughout the product's lifespan. The innovative rotor-hub coupling geometry allows the rotor stems to slide in a radial direction, enhancing the response to high-temperature stresses and deformations. This design achieves a more homogeneous disk temperature without increasing weight, ensuring consistent and reliable braking performance.
  • Improved Load Transfer: The new connecting components ensure a stable and efficient transfer of load between the rotor and hub.
  • Radial Rotor Stem: The radial design improves the rotor's response to high-temperature conditions, maintaining consistent braking performance.

Unmatched Performance for MXGP Riders

The BY4128E Front 270 Batfly EPTA has been praised by main MXGP riders for its improved feeling and power of the braking system. The new EPTA discs provide a more direct and responsive braking experience, allowing riders to feel a powerful and effective brake from the start to the end of the braking event. This innovative design not only enhances the rider's confidence but also improves overall safety on the track. With its new design and shape of the hubs, the BY4128E is a perfect fit for various applications, already available in our catalog for Batfly applications.
  • Proven Performance: MXGP riders endorse the superior performance and feeling of the new EPTA discs.
  • Custom Fit: The new hubs are designed to accommodate different applications, providing a versatile solution for riders.
