This is a nice quality, all metal, dual pull throttle for 7/8 inch handlebars. It is a copy of the old single cable Amal style throttle, and has a throttle stop screw (think cruise control). Includes throttle tube, which is metal as well, this is nice as most new throttles have a plastic tube, but with a metal one there isn’t a chance of the cable breaking the plastic sleeve at the slot where it engages. This is a dual pull setup for dual carb bikes (ie. Triumph Bonneville). Replaces Triumph OEM# 99-0351.
