The TU250 is a single-cylinder, air-cooled, four-stroke, chain-drive motorcycle launched by Suzuki in 1994 as a lightweight, street bike with a standard riding posture and styling resembling the Universal Japanese Motorcycle (UJM) of the 1960s and 1970s. Now in its second generation, the TU250 is manufactured at Suzuki's ISO 14001 certified assembly plant in Toyokawa, Japan and has been marketed in Asia, Oceania and North America.
The first generation TU was introduced to the Japanese domestic market (JDM) in 1994 in both 125cc or 249cc models.
The second generation TU debuted at the 2003 Tokyo Motor Show and was introduced to the JDM for model year 2004 as the ST250 and ST250 E-Type. The bike was introduced to North America with model year 2009 and Australia in 2011 as the TU250X — featuring fuel injection.
Variations of the bike marketed in the JDM and other regions include the VanVan (Asia, Europe), Grasstracker (TU250G)(Asia), Grasstracker Bigboy (TU250GB)(Asia) and Volty(Asia, Europe). Confusingly, the motorcycle marketed in Asia as the Volty was marketed in Europe from 1997-2003 also as the "TU250X".
The second generation, marketed as the ST250, features a 250cc single cylinder four-stroke engine with two valves per cylinder, traditional suspension and tubular steel frame. The aluminum cylinder inner wall is plated with a propriety coating, for light weight and heat resistance. The ST250 E-Type features two-tone fuel tank, polished engine, chromed exhaust pipe, CDI ignition and a kick starter.
Suzuki Motor of America has marketed the second generation motorcycle in North America since model year 2009 as the TU250X — with a hiatus for model year 2010.
The TU's twin valve, single cylinder engine is a higher-compression version of the (carburated) Suzuki GZ250 engine with a closed-loop Electronic Fuel Injection (EFI) system featuring a 32-bit ECU, oxygen sensor, catalytic converter, integral cold-start system, 32mm throttle body and 10-nozzle injector.
The air-cooled engine also features a gear-driven counterbalancer as well as a proprietary cylinder wall plating similar to a Nikasil coating. The coating, marketed as Suzuki Composite Electro-chemical Material or SCEM, is a race-proven nickel-phosphorus-silicon-carbide coating that reduces weight (by eliminating a steel liner) and improves heat transfer, allowing for tighter and more efficient piston-to-cylinder clearance. The engine features an oil sump sight glass, enabling visual oil checks, and uses 87 octane fuel.
Specifications include a five speed transmission with cable-actuated clutch, electric starting (with kickstarter in the JDM), electronic ignition system, maintenance free battery, tubular steel frame with load bearing (stressed member) engine, rear drum brake and front disk brake, chrome-plated locking gas cap, passenger pillion separate from the driver's seat, factory equipped tool kit (under the right side panel), helmet lock, tapered chrome muffler, and chrome wired wheels.
Instrumentation includes an analog speedometer with trip odometer and indicator lights for turn signal, high beam and fuel injection status — as well as a larger fuel warning and neutral light.
Because the 2009 TU has not met California emissions requirements, it has remained a 49-state model.
