Axial to Radial mount adaptor brackets, these enable a 100mm bolt hole centre radial caliper to be used on conventional axial mount forks, these current adaptors available will work with either 78mm, 95mm and 102mm forks . The Great part with these is the same bracket will fit on a number of different models. 78mm Honda CRF 450 2004-2014 95mm Most KTM Models & some CCM 102mm CRF 450 2002-2003 and early CR models. Obviously there are many more forks these will fit as many Jap bikes used the same fitments, i have just listed the ones i know for sure.
