These risers are made to sit at an angle on the yokes. The handlebar slots are at an angle of 27 degrees, which means the look is different from the usual in-line risers. If you want to bolt risers to your sports bike yokes, to streetfighter it, why not be different and try these. They are similar in style to the early Buells. Made for 7/8" bars, and bolt down with M8 Cap Head bolts.
