What crosses over from other bikes to my 2011 250. Wire around rear wheel yesterday knocked out cotter pin on brake pin letting pin fall out. Which in turn let pads fall out but not before breaking one in half. 4 sets of used pads from my 07 don't work. Rode for 4 more hrs no rear brake not fun . Brake pin will be saftey wired from now on. First real ride on my 11 with core exp Love it best bike I've riden to date. Exp works awesome. Its like cheating on tight single track.
