Abstract: A device that is placed over an inlet of a motorcycle gas tank that prevents the overflow of gasoline during the filling of the motorcycle gas tank. The device comprises an upper portion that accepts a gas pump nozzle, an inner core that captures gasoline fumes and provides for pressure build up inside the gas tank, and a lower portion that is designed to mesh with the motorcycle gas tank opening. The upper portion and inner core are basically the same on each model of the device, or motorcycle cuff. The lower portion of the motorcycle cuff is specifically designed to adapt to different types of motorcycle gas tanks, such as flush mounted and indented gas tank openings. The motorcycle cuff gives motorcycle riders the same gas filling advantages of filling their tanks to a desired full level, as those enjoyed by car drivers, by working in conjunction with the automatic shut-off feature available in most gasoline pumps.
