The Suzuki TU250— marketed also as the TU250X, ST250 and ST250 E-Type — is a single-cylinder, air-cooled lightweight street bike manufactured by Suzuki across two generations from 1994 to 2019.
The TU has a single overhead cam (SOHC), unsleeved, four-stroke engine with chain-drive, a standard riding posture and styling resembling the Universal Japanese Motorcycle (UJM) of the 1960s and 1970s.
The second generation TU250 was manufactured at Suzuki's ISO 14001-certified assembly plant in Toyokawa, Japan, and was marketed in Asia (2003–2019), Oceania, and North America (2009–2019). It was discontinued in the home market in 2017, as new, stricter emissions standards were introduced.
