Chunky billet Mono-Clamp Riser. This is made up of two large, swept back riser bottoms, with one top clamp across them. It holds the bars at a height of about 50mm (bar centre). Includes 4 x M8 Stainless bolts. Bolts to your top yoke via a pair of M10 bolts, at a 90mm pitch. It lends itself well to housing small instrument lights, such as LED's etc. Can be made to take all sized bars from 7/8" to 1 1/8" (Fat Bars). The picture show the latter. (top yoke not included)
