Suzuki B-King 600 Streetfighter unveiled

It may not be the 250 bhp turbocharged 1500cc B-King we’d been hoping for, but it’s at least using the B-King styling. It’s the latest “street fighter” and Suzuki took the global wraps off it this week - the much-anticipated all-new GSR600. Like all the new aggressively-styled naked bikes, the GSX-R600 hopes it can bring its unique qualities to the new breed of motorcycle. The culmination of an exciting engine and chassis design program that aimed to create a sporty motorcycle in which ‘modern art meets race technology’… the result is edgy styling and comfort seamlessly blended with performance, technology and handling that is first-class.” Based on the race-proven powerplant of the GSX-R600, the high-performance, liquid-cooled GSR600 engine is tuned for a broader powerband and more low-and mid-range torque.

Incredibly compact, the GSR600’s in-line four-cylinder, four-stroke with DOHC engine incorporates staggered transmission shafts and a three-piece crankcase.

The revolutionary SDVT (Suzuki Dual Throttle Valve) fuel injection uses two double-barrel 38mm throttle bodies with the secondary valve controlled by a 32-bit Engine Control Module (ECM) based on engine rpm, gear and throttle position to produce a seamless, linear throttle response.

Sending fresh air from the airbox to the exhaust ports, Suzuki’s renowned PAIR (Pulsed secondary AIR) system reduces carbon-monoxide emissions.

Incorporating a compact combustion chamber with narrow valve angles, the downdraft cylinder head comes directly from the GSX-R600, while the hollow camshafts reduce weight and advanced cam timing enhances the mid-range torque.

Manufactured using a high-pressure casting technique, Suzuki Super Cast (SSC) pistons are less porous to offer increased strength.

For improved efficiency, the cylinders are integrated into the upper crankcases and coated with Suzuki’s race-proven SCEM (Suzuki Composite Electrochemical Material) to allow better heat transfer and tighter piston-to-cylinder clearance.

The six-speed transmission features primary and internal ratios developed for street use with relatively low first and second gear ratios that are especially convenient for city riding.

Equipped with a 6.5-litre, stainless steel, under-seat muffler, the GSR600’s quiet and efficient exhaust system offers a satisfying engine note from its dual outlets.
