2007 GSX-R1000 Streetbike Features User Selected Traction Control by staff Tuesday, September 26, 2006 Suzuki's '07 hits the street with a new engine managment system. It has three settings: dry, wet and win. Ah just kiddin'. image, thanks suzuki This just in from Suzuki: 2007 SUZUKI GSX-R1000 To the team of Suzuki engineers responsible for the GSX-R1000, Own The Racetrack is not just a slogan, it is a way of life. It's a life dedicated to making the most successful open-class motorcycle in the history of production-based racing even better. The key is the motorcycle's ability to do precisely what the rider wants, when the rider wants, how the rider wants. Accelerate, brake, corner, repeat. Make it easier for the rider, and the results will show. Once again Suzuki has raised the level of open class sportbike performance. The 2007 Suzuki GSX-R1000, it's the reason why Suzuki riders Own The Racetrack. The basic architecture of the compact 999cc liquid-cooled GSX-R1000 engine is well known, a model of race-winning design: Bore and stroke of 73.4mm x 59.0mm, forged aluminum-alloy pistons with short skirts and cut away sides, chrome-moly steel shotpeened connecting rods, hollow dual overhead cams, and lightweight titanium valves. Add to that a close-ratio six-speed transmission with staggered transmission shafts, an adjustable back-torque limiting clutch and a gear driven secondary balancer shaft for reduced vibration. A new more compact Suzuki Dual Throttle Valve fuel injection system is in place for 2007 with 12 smaller holes instead of four for improved fuel atomization and because the injectors are more compact and emit a finer spray, the secondary injectors can be positioned at a steeper 30 degree angle aimed directly at the intake ports for improved throttle response. Intake and exhaust ports are re-shaped and eight percent larger and exhaust valves are 2mm larger (26mm vs 24mm) to work with more aggressive camshafts and Iridium spark plugs are used for optimum combustion and longer life. Also a new Idle Speed Control (ISC) system improves cold starting and stabilizes engine idle under various conditions and larger ventilation holes between cylinders reduces pumping losses. The Suzuki Advanced Exhaust System (SAES) features equal length head pipes feeding a collector, a short mid-pipe and a unique under engine chamber that leads to two short aluminum and titanium mufflers on each side. This system nearly doubles exhaust internal volume while lowering the center of gravity, centralizes the mass and improving aerodynamics. A proven Suzuki Exhaust Tuning (SET) valve finds a home on the mid pipe and the combination of the Suzuki PAIR system, a catalyzer and a oxygen sensor equipped closed loop engine management system work in conjunction to reduce emissions and improve engine efficiency. A new larger radiator features a trapezoidal shape typically seen on works race bikes with nearly a ten percent increase in cooling capacity. The oil cooler is re-shaped with a third more cooling capacity and the oil pump is larger for increased flow. Controlling the new 2007 GSX-R100 is a new engine management system with massive computing power with four times the capacity of the previous models. (Our bold) The new ECM controls not only the fuel injection and exhaust systems but also make it possible for the rider to select from three performance settings to match riding conditions, using a three way switch mounted on the right handlebar. Engine mapping will vary for each setting and each map was developed using experience gained building racebike maps for rainy, mixed and dry conditions. Switching from map to map will be instantaneous making it possible for the rider to use different maps for different sections of the racetrack. A new self adjusting hydraulic clutch system uses a radial master cylinder and minimizes the change in clutch feel over the course of long races.
