My R1 go to warp drive
I've looked high and low and I cant seem to find any reviews or opinions on the Brembo GP4-RS. Also, am I supposed to get the 108MM with adaptors or is it a direct fit? Brembo parts page states it's a direct fit but I recall reading in previous post that you needed adaptors for the M4 version. Does anyone have any insight on this topic. BTW it's an 09 R1...
