Shown here is the complete Bolt-on SUB mount kit for the Honda Grom. SUB mount means "Stabilizer Under Bars", so it literally mounts under the bars. This kit is designed to use oversized handlebars to give the Grom a more stylish look. The SUB mount offers 2 bar positions, stock and 10mm forward and is 43mm taller than the stock bar mounts. Final bar height will be determined by the new bars you use. Standard diameter bars CAN be used with our optional bar reducer bushings. The kit includes everything you need to make the installation a snap. Step by step pictured instructions make it easy.
