Suzuki TS125 model history
1971—

I have tried to tell the Suzuki TS 125 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.

The 125cc two-stroke single cylinder enduro bike TS-125 was introduced for the Japanese home market in December 1970. It had 13 bhp, five speeds and high-drawn exhaust pipe. The TS-125 also had a sister model, a trail version called TC-125 (Prospector in USA) with dual-range gearbox with eight speeds, luggage rack and higher mounted front mud guard that made the bike more suitable for terrain. The TC trail series were built from 90 to 250cc but the whole model series was discontinued in the seventies. The TS series was more successfull and some TS models are still being produced.

”Built like an enduro racer. 5-speed gearbox. Bead stoppers. 9.3" ground clearance. Long travel front forks. 5-way adjusteble rear shocks. CCI automatic lube. Spark arrester. The Duster is a bike that will do 70 mph, take a 34° hill. A bike that's ready to take on competition. As is.” The U-S. Suzuki advertisement for the 1971 TS125R promises a lot. Perhaps it was a competitive enduro racer in those days?

The Japanese street sports model TS125T had different graphics and a close fitting front mudguard, unlike the enduro model (called Duster in USA and Hustler in Japan), that made the bike more suitable for roads, or perhaps for dry trails, than terrain.
