2015+ Yamaha YZF-R1 / R1M / R1S 64mm Under Mount Caliper Bracket

This all new caliper bracket is designed to replace the stock caliper and bracket and allow use of an aftermarket 64mm bolt spacing caliper, which is also relocated to the underside of the swing arm. This allows for simpler wheel changes and a far cleaner aesthetic, comparable to what is seen on MotoGP or World Superbike machines. The bracket is also already configured for use with an endurance-style captive rear brake kit, such as the Fast Frank Racing version. The kit allows plug and play retention of the OEM rear wheel speed sensor. 

Note: We have only found 2 caliper types to work with the OEM wheels, due to clearance issues with the OEM hub. Those calipers can be found here and here. 

Note: This kit does not work with the OEM caliper. An aftermarket, axially-mounted caliper with 64mm bolt spacing must be used.
