In 2006, Suzuki released the GSX-R600, an ultra-compact 600cc supersport motorcycle with top-class performance and a low center of gravity.
The low center of gravity was achieved by providing the bike with a more compact chassis and a 35 mm lengthened swingarm. The riding performance was increased with new suspension elements and brakes to match the response of the new chassis. With the new frame, the three-way adjustable footpegs became part of the standard package.
The model featured a Suzuki Advanced Exhaust System (SAES) with the muffler chamber mounted below the oil pan for a minimized muffler body length.
Compared to the engine packed on the previous model, the 2006 GSX-R600 powerplant was designed to be extra compact, with its height reduced by 20 mm, length shortened by 54 mm, and width reduced by 16 mm.
In addition to the dimensions figures, the engine also featured performance enhancements such as larger titanium valves, wider ventilation holes between the cylinders, and twin injectors.
With all the performance enhancements, the 599cc four-stroke four-cylinder liquid-cooled engine featured by the GSX-R600 developed an output power of 125 hp at 13,500 rpm and 68 Nm (50 lb-ft) of torque available at 11,500 rpm.
The power, combined with a six-speed manual transmission and a dry weight of 161 kg (355 lbs), registered a top speed of 255 kph (158 mph).
