Suzuki GT550

The Suzuki GT550 is a two-stroke, air-cooled, three cylinder 1970s-era motorcycle in Suzuki's "Grand Touring" GT series. Even though total production of the 550 exceeded 60,000 examples spread over a six model year production run, this total was exceeded by both of its three cylinder GT series brothers. Suzuki produced over 80,000 units of the GT750 and over 100, 000 units of the GT380. All three models were originally offered for sale with the beginning of the 1972 model year with the 550 christened "Indy" for the North American market. Apparently, production of the 550 was delayed for some reason because it was not available to dealers in the U.S. until after April, 1972. In Suzuki's numbering scheme, automobile race tracks identify each of its 3 cylinder GT bikes for the North America market: 380 for Sebring, 550 for Indy, 750 for Le Mans.

Due to poor styling, a relatively low top speed and economical pricing the GT550 was more of a commuting and touring bike than a racer, despite its racetrack-derived name.
