Shown here is the complete Bolt-on SUB mount kit for the Honda Grom. SUB mount means the stabilizer mounts under the bars "Stabilizer Under Bars". This kit uses oversized bars to give the Grom a more stylish look, plus a better bar position for the rider. Standard diameter bars can be used also, but require our bar reducers. The kit includes everything you need to make the installation a snap. Step by step pictured instructions make it easy.
