The BATFLY« rotor with WAVE« profile reaches a new evolution. The brake rotors outer track mounts to the newly designed carrier at 6 points; both the carrier and the rivets are now aluminum instead of stainless steel which reduces weight. The carrier is now made of ALUMINUM AL7075 T6 like the rivets; this allows for optimal shape, reduced weight & higher rigidity. The BATFLY grooves on the disc´s surfaces create a self ventilating mechanism allowing the rotor to cool down. Mud and dirt are easily cleaned from the pads surface and outer braking track. The outside and inside disk´s diameter have a round design which allows a better radial expansion of the disk in extreme heat conditions. Carrier and rivets are now made of high performance aluminum and allow a real improvement in handling, thanks to the reduction of the unsprung weight. The brake disc is directional. Verify that it mounts correctly by checking the rotational direction marked on the carrier. Always combine new BRAKING pads with the new disc. Run in as per mounting instructions.
