ITEM DESCRIPTION: Single Cable Open End Throttle Tube with twist stop tab on tube, 5" / 125mm length (22mm ID for use on 7/8" bars). This is a very common throttle tube used on various Scooters ATV's & Motorcycles.
NOTE: I have a similar one in another listing with a semi-closed end and without the stop tab and another one with an open end without the stop tab.
