The SX200 superseded the TV200 as a more reliable 200 cc scooter designed for the world market, but was released at a time when scooter sales, and motorcycle sales in general, were starting to dwindle. The SX benefited from its ability to be tuned for more speed and power, thus making it a favourite with the then-burgeoning scooter racing scene in the UK. Many dealer specials were produced, based on the SX200, including the Arthur Francis "S-Type", Supertune "Rallye", and the Rafferty Newman "Wildcat".
In Italy the SX200 was only available in one colour: white with an ox blood red seat. British models were offered with either blue, black, green, gold, purple or red panelling, whilst other export models offered a choice of seat covering colours, namely green, dark blue and light blue. It also came in a smaller, 150 cc, version, the SX150, of which 31,238 units were built.
