Motorcycle Handlebar Riser-Barbacks - Improve your riding comfort. Riser / Barbacks are the perfect motorcycle accessory for when you find it difficult to reach your handlebars, as they allow you to not only raise the height of your handlebars, you are also able to re-locate them towards you. Now also available as a variable option, which allows you to relocate the barbacks in increments of 5 mm, up to 30 mm. No re-installation requirement, adjustments can be done with an Allen key while risers are installed. Models are available as a bike specific and generic version, for 22, 28 and 32 mm diameter handlebars. The anodized finish protects the risers from scratches.
