Note to ATV owners.  If you are purchasing for an ATV (4-wheeler) with a thumb operated throttle, then leave this page, and go to our ATV section, so the two grips will both have the same internal diameter.  UNLESS you have converted your ATV to a twist throttle like a motorcycle has, in such a case, you are in the correct section.
