Kraus Isolated Straight Risers For Harley Kraus risers are designed to be rigid mounted using the supplied billet bushings. However, the integrated rubber isolators efficiently dampen the vibrations. This innovative design places the isolators closer to the handlebars, providing a drastic reduction of leverage that causes extra wear and failure of the stock style riser bushings.
