I just bought a fully mod drz and has the bbr rear end suspension setup and the guy gave me enough extra parts to almost build a new bike.... but my questions is he gave these brakets, 1 is red 1 is black 1 is blue.... the blue one is on the bike now and he told me he never try the other ones. they are all different sizes and think they have something to do with how the rear end reacts? if anyone can give me any info on these it would be awesome!!! i will post pics of my bike soon once i figure out how to do so!!
