2015+ Yamaha YZF-R1 / R1M / R1S 84mm Under Mount Caliper Bracket Kit

This all new caliper bracket and brake rotor adapter is designed to replace the stock caliper, rotor adapter and caliper bracket and allow use of an aftermarket 84mm 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 kit allows plug and play retention of the OEM rear wheel speed sensor. 

This kit is designed to work with OEM and aftermarket wheels and will accept any 84mm caliper. For aftermarket wheels, the rotor adapter would not be used.
