The Suzuki Bandit is a series of sport standard motorcycles that consists of a number of different models, including the GSF250, GSF400, GSF600, GSF650, and GSF750. All of the bikes in this series come equipped with inline 4-cylinder engines, which have a total of 4 valves per cylinder. Both the 250cc and 400cc models have a water-cooled design. The 600cc, 650cc, 750cc, and the 1200cc models use the Suzuki Advanced Cooling System, which utilizes air cooling as well as oil cooling. The engine that was used in the 600cc model was taken from the GSX-F 600 and re-tuned for mid-range torque. The 1200 cc model uses a bored out version of the GSX-R 1100 engine.
The GSF250 was initially launched in 1989 with an inline 4-cylinder engine that was mounted in a steel trellis frame. The engine that was used for this bike was heavily based on the GSX-R250 engine. The engine in this bike can produce up to 45 bhp and this bike has double front disc brakes as well as single rear disk brakes. Limited versions of this bike have a top fairing, while 'V' models have variable inlet timing.
The GSX400 launched in 1989 with a liquid-cooled inline 4-cylinder engine mounted in a steeel trellis frame. The engine this bike uses is based on the GSX-400 engine and could originally produce up to 59 bhp, but this number was reduced to 53 bhp from 1992 onward. The naked GSF600 N Bandit was released in February and was based on the styling of the previous GSF400 Bandit with a retuned engine from the GSX600. All of the 600 Bandits came with a 15 tooth front sprocket as well as 48 tooth rear sprocket connected by a 530V 110 link chain.
The new Suzuki Bandit 650 and half-faired Bandit 650 and 650S launched only in Tarragona, Spain. For the 2005 version of this vehicle, the engine displacement increased by 56 cc to improve low and mid-range performance. The seat and handlebar were both adjustable for height and the new engine internals make for reduced friction. This model also has a revised four-into-two exhaust system, a reshaped fuel tank, a new halogen headlight, new LCD digital display, and the overall weight of it was reduced. For the 2006 model, there were no significant changes.
The 2007 version of the Bandit came with a whole new water-cooled motor that was designed just for the 2007 Bandit 650, which was a departure from the previous models which had engines that were re-worked from other models. A majority of chassis as well as the bodywork remained unchanged from the 2005 model. This vehicle meets all Euro3 emission standards, is capable of up to 85 horsepower, 12,500 rpm redline, has a hydraulic clutch lever, is 14 kg heavier than its predecessor, and comes with electronic fuel injection with dual throttle valve system.
In November of 2008, Suzuki announced that certain changes were being made to the 2009 GSF650. There were to be changes to both the naked and half-faired versions, including sleeker headlights, re-shaped exhaust ends, slimmer tail lights, and slightly different frame covers. The GSX650F was initially produced in 2008 and is a variation of the Bandit 650 with many of the same components. While this vehicle is built on a bandit chassis, the additional lower fairing provides it with a sportier look that resembles the Suzuki GSX-R. The GSF750 was released in Japan only that used some of the parts from the 600 and others from the 1200 models. The front frame cradle on this vehicle was the exact same as the 600 and the rear subframe was identical to the 1200.
