The SST 250 was a small Italian road-going two-stroke single from Cagiva's early years, built in the Varese factory at the end of the 1970s. It paired a 243 cc air-cooled engine with a five-speed gearbox, a front disc brake and a drum at the rear. The ignition started out as points and coil and was later changed to electronic CDI. A Chopper-styled variant was sold alongside it.
