These isolated risers are designed to be solid-mounted to the top triple tree and are installed with the supplied billet bushings. This creates a much more rigid bar setup; allowing for improved control and far greater use of your bike''s suspension and braking capabilities. As for vibration dampening; the rubber bushings are relocated just below the handlebar. There they are placed inside the riser mid-section. The proprietary use of these rubber isolators drastically reduces the amount of unwanted movement at the bushings. This creates a much more solid bar feel; giving you greater confidence in your bike''s handling.
