Suzuki Mini CRO 75 (CM75)
1975—1977

I have tried to find some Suzuki CM 75 / Mini CRO 75 info to put on this page. 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.

Launched in 1975, the Suzuki Mini CRO 75 (model code CM75) was a small off-road bike with a black-painted 72cc two-stroke single cylinder rotary disc valve engine, a long stroke Ceriani type front fork, twin shock/coil spring rear suspension, down-up exhaust pipe, drum brakes front and rear and equipped with small-diameter block pattern tires. The model name derived from ”mini motorcrosser”. A similar sibling model, the Suzuki Mini CRO 50 (CM50) was released shortly after the CM75. The models shared the same tubular frame, suspension and wheels. The models were practically identical, apart from the engine and transmission. The Mini CRO 50 had a five-speed return transmission while the Mini CRO 75 transmission had four speeds. Both 50 and 75 versions of the Mini CRO were discontinued after only three years on the market.

The 1975 Suzuki Mini CRO 75 was offered in two colors, Red and Yellow. At first, the Mini CRO had motocross-type high mount front fender, that was changed to a low mount fender, more suitable for riding on the streets.
