Had a little time to make a proto type piece here to verify fitment and check operation. I am using Frank's captive spacers in the front wheel. Please give me some feedback and or interest in it so I can get a price on having some CNC'ed. Works very well, just loosen pinch bolts and axle and withdraw the axle. The caliper even with the 320 rotor can stay attached/torqued to base. Super simple like gsxr quick change set up. Drill and tap 3 (4x.7) holes in left fork base, using captive bolt for template, no other needed mods or parts. Frank does have a rear quick change set up to go along. Price should be very reasonable on my captive bolt, will come with attaching bolts. You will need 1/8'' drill or #30 bit, and a 4 x.7mm tap. Does not support axle sliders (most quick changes do not). This works on stock or cup forks. Thanks.
