Patented Batfly design improves the rider’s feeling & response during braking. Grooves on the disc’s surfaces create a self-ventilating mechanism, allowing the rotor to cool down efficiently. Includes an oversized bracket that perfectly repositions the caliper to correctly align the pads with the 280mm disc. Mud and dirt are easily cleaned from the pads’ surface and outer rub surface. The outside and inside disc’s diameter have a non-round design which allows a better radial expansion of the discs in extreme heat conditions. Batfly system cleans and renews the pad surface with each pass on the grooves, maintaining the friction coefficient of the pads at the maximum level, even in the worst environmental conditions. The connection between stainless steel rotor and aluminum hub is given by pins, creating a floating structure of the disc, ensuring the best interaction with pads/caliper and increasing the performance. Thanks to special grooves on the outer braking surface, heat is dissipated & the brake pads are effectively cleaned at each pass over the grooves while braking.
