Bonamici parts are made in Italy with a dedication to track-oriented riders.
Bonamici clip-ons are machined out of billet aluminum to ensure the highest quality and strength. These clip-ons will allow you to easily find the perfect feeling when riding at the highest levels. Ergonomics and comfort are everything when attacking a corner at full speed. Leverage on the front end will allow you to more precisely guide your motorcycle through the corners which will lead to confidence in your setup.  Â
All Bonamici Racing handlebars have a downward angle of 6.5*.
Delrin end caps are included with these handlebars and are easily removed for the installation of handlebar controls.
