2012 Suzuki GSX-R1000 Review
Introducing the new 2012 Suzuki GSX-R1000. Faster evolution is a hallmark of the GSX-R1000’s engine. Reaffirming the legendary motorcycle’s claim to the top are improved throttle response, increased power and acceleration at mid-range engine speeds, and better fuel economy.
The GSX-R1000 offers incredible engine performance from idle to red line, smoother suspension performance, even more responsive handling and superior braking performance - everything needed to Own The Racetrack.

Chassis enhancements deliver even better control. And styling refinements evoke the performance and handling advances.
Faster evolution is a hallmark of the GSX-R1000’s engine. Reaffirming the legendary motorcycle’s claim to the top are improved throttle response, increased power and acceleration at mid-range engine speeds, and better fuel economy.
The 2012 GSX-R1000’s engine combines advances in design, performance, and fuel efficiency with the fundamental elements that helped to create the GSX-R legend. Key benefits include better throttle response, more power and acceleration at mid-range engine speeds, and approximately 8% better fuel economy*.
The single exhaust and a revised exhaust-pipe length enhance output at low and mid-range engine speeds, so acceleration is quicker. Advances inside the engine begin with the pistons. The benefits are more torque and better acceleration at low and mid-range engine speeds, better throttle response, and lower fuel consumption. Here too, the benefits are more torque and better acceleration at low and mid-range engine speeds, better throttle response, and lower fuel consumption.
The reduced inertial mass gave Suzuki the freedom to optimize the valve lift curve. Consequently, Suzuki used MotoGP technologies to revise the exhaust cam profile for a slight reduction in valve overlap (the period when the intake and exhaust valves are both open), thereby increasing the engine’s racetrack performance potential.
Suzuki adopted race-proven specifications and technologies elsewhere in the engine. The shaft positions allow the engine to be optimally short from front and rear. An engine control module ( ECM ) provides state-of-the-art engine management and has newly optimized settings to suit the engine refinements and single muffler.
As the rider opens and closes the primary valve, the ECM reads the throttle position, engine speed, and gear position and incrementally adjusts the secondary valve to maximize the intake-charge velocity. The ECM thereby enhances combustion efficiency, makes throttle response more linear, and improves low-end and mid-range torque.
The secondary injector is aimed at the secondary throttle valve and operates to add fuel for high-engine-speed, high-load conditions. A Suzuki Exhaust Tuning (SET) servo-controlled butterfly valve in the exhaust pipe helps to maximize torque throughout the rev range in diverse running conditions by optimizing the exhaust-system back-pressure in accordance with the engine speed, throttle position, and gear position. An ECM-controlled Suzuki Pulsed-secondary AIR-injection (PAIR) system injects fresh air from the airbox into the exhaust ports in accordance with the engine speed and throttle position, thereby further reducing emissions by promoting the ignition of unburned HCs .
The unique Suzuki Drive Mode Selector ( S-DMS ) system allows the rider to select from three fuel-injection and ignition-system maps, thereby adjusting power delivery to suit personal preferences.
The “C” setting yields relatively soft throttle response throughout the throttle-opening range by reducing engine power.
With superior balance and precise control, the GSX-R1000 rider can take maximum advantage of the winning performance.
The 2012 GSX-R1000’s chassis represents an evolution in terms of cornering and stopping performance—an evolution that gives the rider even greater control and allows the rider to take better advantage of the engine performance.
Evolutionary advances can be seen in the front brakes, front forks, front and rear tyres , and front axle. Increased piston diameters mean better braking performance. The calipers and discs are 130 grams lighter overall.
Superior braking performance combines with hard-braking stability yielded by enhanced front forks to realize great capability on the racetrack. The shock has adjustable rebound damping, spring preload , and high-speed and low-speed compression damping.
Thanks to Suzuki’s uncompromising efforts to shave excess weight, the 2012 GSX-R1000 is 2kg lighter than its predecessor. The lower weight and precise weight balance allow higher speeds on straightaways and corners, so they translate into faster laps.
A narrow lower fairing also cuts drag. Newly evolved styling details evoke the bike’s newly enhanced performance and handling. Own The Racetrack.
2012 Suzuki GSX-R1000 Key Features
* Thanks to Suzukis uncompromising efforts to shave excess weight, the 2012 GSX-R1000 is 2kg lighter than its predecessor.
* The 4-2-1 exhaust system, carrying a Suzuki Exhaust Tuning (SET) valve maximizing torque and improving throttle response, particularly in the low-to-mid rpm range. * Lighter, more durable forged pistons designed with the same Finite Element Method (FEM) and fatigue analysis technology used for MotoGP racing engines, and consequently the pistons are 11% lighter.
* Optimised camshaft profiles for great racing potential, developed using proven MotoGP racing engine technology.
* The lightweight and high-grip front and rear tyres reduce unsprung weight for sharp handling.
* 999cm3 4-cylinder engine with Bore x Stroke of 74.5mm x 57.3mm brings enhanced throttle response across the entire rpm range and high potential for racetrack performance.
The compact engine enabled short wheelbase and 32mm long swingarm at the same time to improve racetrack performance.
* Suzuki Composite Electrochemical Material (SCEM)-plated cylinders integrated into the upper crankcase, reduce friction and improving heat transfer, durability and ring seal.
* 12-hole fuel injectors produce a fine fuel mist for more complete combustion, reducing fuel consumption and exhaust emissions.

Large, efficient radiator with a trapezoidal shape developed on Suzukis factory team race bikes and a trapezoidal engine oil cooler both help reduce drag.
* The rear brake system with single-piston calliper contributes to a reduction of unsprung weight.
* Rear shock absorber features adjustable rebound damping, spring preload, and both high-speed and low-speed compression damping.
* Electronically controlled steering damper provides lighter steering at slower speeds and more damping force at racetrack and highway speeds.
