The Yamaha RXS 100 is a two-stroke air-cooled single cylinder 100cc motorcycle with a 5 speed manual transmission, manufactured between 1985–1996. The RXS is a nice, reliable, popular little bike, which is an ideal runabout, but needs well maintaining, with lots of chrome which will rust if not protected. The drawbacks are the electrics and the front drum brakes which aren’t the snappiest.
