Massive risers made by the German company Ritz. Machined from billet aluminum with unique features. They have special screw-on top covers to hide the clamp bolts for an extra-neat look and they are drilled hollow to route wires and/or cables inside the handlebars. These risers mount to the upper triple tree with 22 mm hollow bolts and nuts. There are optional reducers for the bore that takes the rubber bushings on stock triple trees.
