These machined grips for 1 inch handlebars offer a stark alternative to typical rubber motorcycle grips. The right-side grip serves as a grip and throttle tube all in one and can be used with single or dual cable setups and with whichever throttle housing you choose. The left-hand grip is held on with three small set screws and can be tightened and locked in place with the included allen wrench. Machined out of solid aluminum and guaranteed to handle all the miles you can throw at them. Fits Harley-Davidson Big Twin and Sportster motorcycles with 1″ handlebars and cable-operated throttles.
