Moving the rear caliper isn't required to track the Aprilia RS660, but it does make changing the rear wheel a bit nicer.


3.5 x 0.6mm fasteners allow you to bolt to the axle bolt and create a captive hanger for a no-fuss wheel change at the track.  Stock wheel speed sensor moved to the bottom under that axle and protected with a small lip to keep it safe from any wondering brake discs.


Works with or without ABS.  It does not work with stock brake lines.


Pre-Orders available till end of January.  Shipping 2nd week of March.
