Like caveman has observe, a low-seat S model is a rare gem and an excellent transition for a Harley rider who is accustomed to a lower riding postition. The color is called Red Topaz Violet. The fuel cap assembly on yours should be detached then rotated 180º to allow water to drain from around the tank's cap recess during rain or from condensation, instead of infiltrate the fuel in the tank. Rotating it will allow a notch in the assembly to align with a port in the tank recess attached to a pipe that exits from the bottom of the tank. The pipe empties into a cup that's attached to the frame, or a hose that's routed behind the throttle-side footpeg plate.
