I have a set of the Bikers Choice adapters to mount 00 and later calipers onto 99 and older forks. I'm using stock 2 piston calipers but have a line on either a set of later model bagger brembos or perhaps a set of XR1200 calipers if I act fast. I'm using stock 11 1/2in floating rotors off a Sportster S on 13 spoke mags. I thought I saw somewhere the swept area when using brembos on the smaller rotors is wrong? Can't find where I read that though. Anyways need the info. thanks

 

Did you ever find anything out?
Did you get the Sportster calipers?

 

The brembos will work fine with the 11.5 rotors. However, they should be used with the 11.8 rotor I believe.
