Competitively priced: The all-new Suzuki GSX-S1000 family offers a trio of models: the naked GSX-S1000 ($9,999), GSX-S1000 ABS ($10,499), and fairing equipped GSX-S1000F ABS ($10,999). These prices put all three models well less than those of other competitors in the category.
Superbike roots: The engine is based on the 2005 GSX-R1000 and therefore features a longer stroke than the current GSX-R1000 supersport for greater torque production in the low-to-mid rpm range. This engine has the same 44mm dual-throttle valve (SDTV) throttle bodies as the 2K5 GSX-R and the same ports and valve diameters, although the valves are now stainless steel rather than titanium. Cam profile and timing has been altered to optimize torque output. The gearbox is straight out of the GSX-R but with a standard non-slipper clutch. Final gearing is shorter with two teeth added to the rear sprocket, while engine redline is set at 11,500 rpm (2,000 less than the GSX-R). Claimed peak output is said to be 145 horsepower at 10,000 rpm with 78.2 pound-feet of torque at 9,500 rpm, measured at the rear wheel.
Anti spin: The GSX-S features Suzuki Traction Control II, a system similar to that first used on the current V-Strom 1000. The system is tuned for a sportier application, offers an additional (third) level of adjustability, and can be turned off completely. When rear spin is detected, ignition retard is implemented to regain traction.
Feather weight?: The GSX-S is touted to be the lightest in its class. The main frame is lighter than that of the GSX-R unit, while the gull-type swingarm is straight off of the Gixxer. Claimed curb weight is 456 lb. for the naked model (add 5 lbs. for ABS), and 472 lbs. for the faired GSX-S1000F. Fuel capacity is 4.5 gallons, which is slightly less than its competitors, so factor that in for a fair comparison.
Chassis highlights: A 57.5-inch wheelbase and sporty steering geometry (25-degree rake/3.9-inch trail) indicate a great balance of agility and stability. The monobloc four-piston Brembo calipers and 310mm front rotor combo look to be the real sporty deal, as does the fully adjustable 43mm inverted KYB fork. The KYB shock features a ramp-style preload adjustment collar and rebound-damping adjustability. I'm hopeful that the shock compliments the high-quality components evident elsewhere on the machine. We will learn soon enough when I ride the naked and faired GSX-S models at today's press launch staged in Monterey, California.
