Faster evolution is a hallmark of the GSX-R1000's engine. And 2012 brings another quick step ahead. 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. Refinements ranging from a new stainless steel 4-2-1 exhaust system to completely redesigned pistons. The chassis, suspension and braking systems have also been refined for enhanced performance resulting in a reduction in weight of over four pounds.
For 2012, the GSX-R1000 lets everyone know at a glance that it's the latest generation of the championship-winning supersport bikes that have dominated racetracks around the world. It features new colors and a variety of new styling elements, including new sporty instruments, new black fork tubes and new red pinstripes on the wheels. Put it all together and the GSX-R1000 offers incredible engine performance from idle to redline, smoother suspension performance, even more responsive handling and superior braking performance - exactly what you need to Own The Racetrack.
New 999cc four-cylinder powerplant is modified to deliver extraordinary acceleration matched by maximum top-end performance of world-class racetrack performance.
Race-proven designs include high-quality titanium valves, forged pistons, shot-peened conrods and large intake and exhaust valves.
Pentagonal cut-outs in the sides of each cylinder bore have been enlarged and reshaped. The greater opening area makes the crankcase lighter. The shape of the ventilation holes - wider at the top, narrower at the bottom - matches the actual flow of the trapped air, reducing pumping losses due to internal crankcase air-pressure resistance to downward piston movement.
New 4-2-1 exhaust system is significantly lighter, contributing to improved agility and handling. It is also increased mid-range engine power output further improving acceleration out of the corners.
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.
Finite-Element-Method (FEM) and fatigue-analysis techniques honed in development of MotoGP racebike engines were applied in making the pistons 11% lighter while retaining the same reliable level of strength and durability. The performance advantages translate into quicker acceleration and improved fuel economy.
Crankcase is refined with larger pentagonal cut-outs in the sides of each cylinder bore. The shape of the ventilation holes reduces pumping losses due to internal crankcase air-pressure resistance to downward piston movement.
Advanced technology from MotoGP competition was applied in modifying the camshaft profile. Thinner material for the tappet skirts results in a weight saving of 2.5 grams per tappet, reducing inertial mass and allowing optimization of the valve lift curve.
Thinner material for the valves' tappet skirts saves 2.5 grams per tappet, which reduces inertial mass and allows optimization of the valve lift curve.
An Engine Control Module (ECM) provides state-of-the-art engine management and has newly optimized settings to maximize the benefits of the new 4-2-1 exhaust system and other engine refinements.
Suzuki Ram Air-Direct (SRAD) air intakes are positioned close to the centerline of the fairing to provide optimum intake efficiency. The intake-duct openings feature a louvered design that heightens intake efficiency, while also contributing to weight reduction.
Suzuki Dual Throttle Valve (SDTV) system uses two butterfly valves (primary and secondary) in each throttle body barrel. 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 result is a system that realizes the benefits of near-linear throttle response and torque output across the entire rpm range.
Suzuki Drive Mode Selector (S-DMS) system allows the rider to select one of three fuel injection and ignition system maps, adjusting power delivery to suit personal preference. The mode selection switch is mounted on the left handlebar and its two buttons can be easily operated by the thumb and index finger.
Suzuki Composite Electrochemical Material (SCEM) plated cylinders integrated into the upper crankcase helps reduce friction, improve heat transfer, increase durability and provide better ring seal.
The back torque-limiting clutch incorporates the Suzuki Clutch Assist System (SCAS) for light clutch pull and optimum clutch performance. The back-torque limiter offers smoother downshifting, and thereby lets the rider take full advantage of engine output during deceleration.
Twin-spar frame features an exceptionally short wheelbase and uses just five cast aluminum-alloy sections and an aluminum-alloy swingarm with just three castings.
The compact engine allows a longer swingarm and shorter overall wheelbase for improved racetrack performance.
The footpegs can be adjusted to any of three positions in a 14mm horizontal and vertical range. The rear brake pedal and master cylinder move with the right footpeg assembly, and the shift-lever linkage can be adjusted to accommodate changes in the position of the left footpeg.
Lightweight 43mm Showa Big Piston Front forks (BPF) are refined to match the GSX-R1000's reduced weight. Their design offers more effective valving, with more controlled compression to deliver better feedback to the rider and enhance the rider's ability to make line corrections while cornering.
The Showa rear shock works through an aluminum alloy linkage mounted on the swingarm and an extruded aluminum alloy link rod connected to the frame. The rear shock offers adjustable rebound damping, spring preload, and both high-speed and low-speed compression damping.
Electronically controlled steering damper contributes to handling stability and a more alert and agile feel by increasing the damping force at higher speeds and reducing it at lower speeds.
New front axle is 38.9 grams lighter, further reducing unsprung weight and thereby improves handling.
New 5mm front brake discs made of heat-resistant stainless steel work together with new top-of-the-line radial-mount Brembo monobloc calipers. The monobloc calipers are lighter and more rigid than conventional bolt-together calipers, giving better feedback to the rider. As a result, the calipers and discs are 130 grams lighter.
The rear disc brake works with a single piston Nissin caliper mounted above the swingarm. The caliper's compact design contributes to a reduction of unsprung weight.
New front and rear tires have improved tread patterns and the front tire is 200 grams lighter, contributing to lower unsprung weight and sharper handling.
New high-grip leather seat features outstanding holding properties, providing the rider with a greater sense of stability when accelerating.
