The Suzuki SP370 is a motorcycle produced by Suzuki from 1978 to 1979. The Suzuki SP370 was the first Suzuki motorcycle with a single cylinder four-stroke engine, if you don't count the short-lived Colleda CO and COX models from the fifties. Unfortunately it had a bit too weak engine and it was a bit too expensive to become a great success. Yamaha, for example, could offer a 500cc trail bike for the same money as you had to pay for the SP370. It was made in the US from 1978-1979. Suzuki produced an enduro oriented variant in the Suzuki DR370

Colors: Red, Silver. Initial frame number: SP370-100001.
