In 2008, Suzuki released the GSX-1300BKA B-King, Hayabusa's first cousin came with an aggressive style and attitude. The model featured a slightly modified version of the 2008 Hayabusa engine topped by a state-of-the-art chassis and suspension that offered enhanced all-around capabilities, a sharp acceleration, and responsive handling.
The performance capabilities of the two bikes were not so different, except the B-King delivered smooth and strong power in the low-end range and featured some unique chassis components, such as a finely crafted swingarm.
The real difference was the outfit, with the engine placed in plain sight and the massive twin exhaust mufflers placed under the seat. The bike featured a new twin-spar aluminum frame with optimum rigidity and a new cast aluminum swingarm that offered superb handling.
In the power department, the 2008 Suzuki GSX-1300RBKA B-King packed a Suzuki Dual Throttle Valve (SDTV) fuel injection system with two injectors per cylinder and a Suzuki Drive Mode Selector (SDMS) system, which offered three engine map settings for various riding conditions and personal performance preferences.
It also featured lightweight titanium intake and exhaust valves for high combustion chamber efficiency, a new 32-bit ECU for high performance, and a large volume four-two-one exhaust system with a large capacity catalyzer.
At its core, the 1,340cc four-stroke four-cylinder liquid-cooled engine delivered an output power of 181 hp at 9,500 rpm and 146 Nm (108 lb-ft) of torque at 7,200 rpm. Combined with a six-speed manual transmission and a dry weight of 235 kg (518 lbs), the bike reached a top speed of 254 kph (158 mph).
