I have tried to tell the Suzuki Hi (CA19A) / Hi R (CA19B) model history on this page as I know it. The page is still under construction. I would be grateful of any contributions — sales brochures, magazine ads, magazine articles, pictures, specs, facts, corrections etc. Please scan the material in JPEG format (large enough that all the details are visible) and send them to me. Please tell me the source and the publication date if possible. If you send me pictures of your own bike, please follow these instructions.

1986 Suzuki Hi / CH50S lineup, four different color options shown here

Suzuki lauched the AE50 scooter in Japan in December 1985, with a model name ”Hi” (Japanese for 'Yes' but I don't know if that was the meaning of the model name, could be just the greeting, equivalent to 'Hello'). It was a lightweight (48 kg/106 lbs) scooter with 10-inch wheels, a powerful (6.5 bhp) 2-stroke engine and The first models had very colorful livery, using striking 2-tone colors with the second color matching the wheels, floor, mirror and handlebar grips. The Hi-R debuted in 1987 as the successor to the Hi. Its suspension has been refined with anti-nose dive suspension and high-grip tires. The rear spoiler and unique front fenders are also exclusive to the Hi-R.
