This kit is designed to be used with the stock triple clamp and oversize handlebars. The Rubber SUB mount bolts to the stock triple clamp and converts your solid mounted triple clamp into a vibration-absorbing rubber mounted handlebar, while incorporating the SUB mounted stabilizer to slip in under the bars. MED and SOFT compound bushings are provided. The SUB mount locates the bars between the #2 and #3 positions. Step by step pictured instructions are included along with all the necessary hardware. Standard diameter bars can be used in some cases but would require our Bar Reducers which are available here, on line, as an option, if needed. The Kit also include the cable guide but not the large knob in this photo.
