EBC X Series Front Brake Disc for Honda VFR800. These X and XC Floating Motorcycle Discs are the lightest brake discs available, designed to eliminate vibration issues and offer a longer lifespan than conventional rotors. They utilize round button technology and feature six drive buttons, reducing unit weight by up to 300 grams. X-Series discs have full circle, circular rotor blades, while XC-Series discs have a contoured, lighter weight profile. Each disc is meticulously hand-built and inspected to minute tolerances, ensuring the highest quality. The patented square drive button system effectively prevents warping and vibration during heavy braking. Both X & XC Floating Motorcycle discs are equipped with mill-hardened stainless steel high-friction rotor blades for optimal braking performance and are direct size-for-size replacements.
