Recess dept: 2mm. These spacers have dowel locator on one end (dowels are mostly found on calipers of R1, R6 or suspension fork bottoms) and collar on the other. Those are used for caliper or disc conversions and will fit all calipers with M10 bolts as found on all radial calipers on For BMW, Ducati, Suzuki, Kawasaki, Yamaha etc.
