The Biltwell Utility Mirror for bar end fitment blends classic café racer styling, precision optics and modern material and manufacturing technologies to create the perfect motorcycle mirror. Every Biltwell Utility mirror can be modified for left- and right-hand applications, but safe, correct installation depends on the style of throttle tube, the internal diameter of handlebar, the existence of internal bar end mechanisms (if any), and other variables. Please make sure the end of your motorcycle's throttle tube is open, and that the inside of the handlebar will accept our Utility mirror's wedge mechanism BEFORE attempting to install this mirror on the right side of your handlebar.
