Vespa Sprint

The Vespa Sprint is a 150 cc two-stroke scooter that Piaggio built from 1965 to 1976. It came in two versions: the early Sprint, made until 1974, and the Sprint Veloce, made from 1969 to 1979. The main change in the Veloce was the engine, whose old two-port design gained a third transfer port at the top end, and the compression ratio rose from 7.5 to 1 to 7.7 to 1. The first models had no turn signals, but every Sprint Veloce imported to the United States after 1973 was fitted with them as standard to meet American regulations. In India, Bajaj Auto used the 150 Sprint design in 1972 to replace its licence-built Vespa 150 Super with the 10-inch wheeled Bajaj Chetak.
