Chassis

• Frame: New cast-aluminium twin-spar frame composed of five sections. The new frame is designed with emphasis on weight reduction. Material thickness of each frame section has been carefully optimized (the thinnest section has been narrowed from 3.5mm to 3.0mm), resulting in frame weight reduced by 1,350 grams. The seat rail is now narrower, making it easier for the rider to straddle the machine. In order to further optimize chassis dimensions, the wheelbase has been shortened by reviewing the layout of the frame and other sections, while keeping the swingarm length the same.
• Front suspension: The front suspension newly features inverted telescopic type Big Piston Front-forks (BPF) made by SHOWA and developed with racing-technology feedback. The forks use 41mm-diameter inner tubes and the overall fork assembly, in particular the fork outer tubes, are newly designed. The BPF design relocates the fork springs to each fork leg, where they are completely submerged in oil. This reduces fork oil foaming and thus contributes to a more stable damping performance. Damping force and spring preload are both fully adjustable.
• Rear Suspension: The rear suspension comes with fully adjustable spring preload and rebound and compression damping force. Compression damping is a 2-way – high-speed and low-speed – adjustable type, making possible precise settings. A ride-height adjustment system is equipped.
• Swingarm: Swingarm design has been reviewed, resulting in a weight reduction of 900 grams. The cushion lever is changed to pressed aluminium, from forged aluminium in the current model, while the arm structure is changed from die cast and plate to a cast, contributing to its weight reduction.
• Braking System: The front brake system uses newly designed Brembo monoblock-construction cast-aluminum-alloy calipers, which feature high caliper-body rigidity and light weight. The 4-piston calipers are radial-mounted. The rear brake uses a compact and lightweight caliper shared with the GSX-R1000. The overall brake system is designed to heighten brake feel, with the goal of delivering better brake performance on racetracks.
• Riding Position: Taking advantage of the 15mm-shorter wheelbase, the new riding position puts the handlebars at a shorter distance from the rider’s hip point, and the handlebars are placed relatively low. The new riding position offers a high degree of comfort and freedom of rider movement. The handlebars are positioned at a 1-degree wider angle and the fuel tank shape has been reviewed taking into account various riding situations, such as tucked-in at racetracks, sport riding, handling through streets, long rides where comfort becomes more important.
• Seat: For user convenience, the GSX-R750 has a relatively low seat height of 810mm. The sections around the seat are shaped slim for easy straddling and knee grip. The seat is shaped to allow much freedom of moving the rider’s hip point, and to help make the rider’s knee and angle positioning comfortable. The seat and surrounding sections are shaped to allow smooth rider weight transfers on racetracks. The seat skin is upgraded. The weight of the seat section is reduced by 244 grams, by reducing the material thickness at the bottom of the front seat and by using a more compact pillion seat.
• Adjustable Footpegs: As with the current model, the footpegs are 3-way adjustable, enhancing the freedom of assuming different riding positions.
• Electronically Controlled Steering Damper: An electronically controlled steering damper contributes to handling stability and a more agile feel by increasing the damping force at higher speeds and reducing the damping force at slower speeds.
• Front Axle: The front axle shaft diameter is reduced from 25mm to 22mm, reducing weight by 46 grams (tightening structure changed from an inside-axle screw/hollow bolt type to an outside-axle screw/nut type).
• Front Wheel: Hub and bearing sizes are reduced in accordance with the smaller-diameter front axle, resulting in a weight reduction of 210 grams as a whole. Only the hub section is changed to match the change in axle size; design remains unchanged. Wheel sizes are 17 M/C x MT3.50.
• Rear Axle: Rear axle diameter is reduced from 28mm to 25mm.
• Rear Wheel: Hub and bearing sizes are reduced in accordance with the smaller-diameter rear axle. Along with the sprocket drum, the total weight was reduced by 240 grams. Wheel sizes are 17 M/C x MT5.50.
• Tyres: Carried over from the current model, Bridgestone’s high-performance sport tyres are employed to realize running performance, top performing the handling and grip.

 Engine

• Performance: Highly refined balance of a state-of-the-art 750cm3 machine. Lighter weight and reduced mechanical losses result in enhanced running performance. Upgraded engine performance in the low-to-mid rpm range (more torque and power) results in more accessible, more controllable engine performance characteristics. Fuel mileage is improved by approximately 10% (WMTC mode, Suzuki in-house research). In addition to a combination of lighter engine weight and reduced mechanical losses, the progression of combustion efficiency and the reduction of overall weight also contributed to this improvement. Suzuki Drive Mode Selector (S-DMS) system with further-refined two-map selection enables adjustable performance.
• Piston Rings: The upper compression ring and the oil control ring are chrome-nitridecoated using a Physical Vapor Deposition (PVD) system.
• Valve Design: The intake valve is now made of the same titanium quality as the new GSX-R600. The intake valve head taper angle is also changed.
• Crankcase: The pentagonal-shaped ventilation holes at the top of the cast crankcase are both more functional and larger, thus contributing to both weight reduction and airflow.
• Suzuki Composite Electrochemical Material (SCEM) - plated cylinders: As on the current model, the cylinders are plated with SCEM, Suzuki’s well-proven, racing-derived, nickel-phosphorus-silicon-carbide coating technology.
• Compact Engine Design: The engine is rotated rearward by 3 degrees around the driveshaft to reduce the wheelbase to further heighten racetrack performance.
• Back-torque Limiter: The back-torque limiter makes for smoother downshifting operation, and helps the rider make effective use of the powerful engine output and chassis performance.
• Suzuki Drive Mode Selector (S-DMS): S-DMS allows the rider to select a power character to suit the rider’s personal preferences in various situations. The latest version features a 2-map selection designed pursuing performance merits and ease of use. The S-DMS selection switch is moved to the left handlebar for smoother operation.
• Suzuki Dual Throttle Valve (SDTV): The SDTV system uses two butterfly valves in each throttle body to realize fine control of fuel injection. The primary injector angle is changed from 41 to 35 degrees to optimize the direction of fuel spray. The system uses fine-spray-type primary and secondary injectors. The injectors are now more compact, allowing more freedom of layout (the new layout also resulted in the air cleaner attaching section changed to a flange type).
• Idle Speed Control (ISC): ISC constantly maintains stable idling operation, greatly enhancing user comfort. The Engine Control Module (ECM) senses and calculates the difference between actual idling rpm and normal idling rpm; an ISC valve located in the throttle body bypass circuit is opened or closed by a stepping motor to regulate the amount of intake airflow and thus compensate to reach the normal idling rpm.
• Engine Control Module (ECM): Using feedback from MotoGP technology, the ignition driver is changed to an advanced transistorized ignition control circuit, improving performance. The ignition circuit has been reviewed. Countermeasures against heat have been taken. The ECM is now located near auxiliary equipment, and the wire harness routing has been improved to reduce the amount of wires, resulting in weight reduction of 250 grams.
• Iridium Plugs: As with the current model, the engine uses efficient and durable iridium spark plugs.
• Muffler: The new-design muffler is more compact and lighter. The 4-into-1 exhaust system is composed of stainless-steel exhaust pipes, an exhaust chamber and a titanium muffler. Thinner exhaust-pipe wall thickness (reduced from 1.2mm to 1.0mm) and more compact chamber and muffler save weight (the exhaust pipes and chamber together are 600 grams lighter, while the muffler is 500 grams lighter).
• Suzuki Exhaust Tuning (SET): As with the current model, the exhaust system is fitted with SET system, an exhaust device that opens/closes a butterfly valve in accordance with the engine rpm.
• Pulsed-AIR (PAIR) injection: Built-in PAIR system greatly contributes to environmentally conscious performance. The PAIR system directly injects fresh air from the air cleaner box into the cylinder head exhaust port – through a PAIR control solenoid valve which is controlled by the ECM in accordance with throttle position and engine rpm – to react with unburned hydrocarbons (HC) and thus reduce carbon monoxide (CO) emissions.
• Air cleaner: To further optimize the air-cleaner layout, the shapes of the air cleaner and intake pipe are changed. The changes also realize a weight reduction of 60 grams.
• Radiator: The radiator fan is enlarged (diameter increased from 171mm to 180mm) for better cooling performance.
• Instrument Cluster: The instrument cluster is a full function type shared with the 2010 GSX-R1000. A gear position indicator is carried over from the current model. Stopwatch and lap timer are newly added, and the LCD is enlarged. The engine rpm indicator is derived from MotoGP machines. Unlike that of the current model which can be programmed at only one rpm setting, the indicator can be programmed for four different rpm settings. The indicator can be used as a reference for up-shift timing on racetracks and on winding roads.
• Handlebar Controls: The S-DMS selection switch is moved to the left handlebar, from the right handlebar in the current model. Meter display selection switch on the right handlebar can control the stopwatch and lap timer, and measure times up to 99 minutes and 59.99 seconds.
• Immobilizer: Immobilizer is standard equipment. The immobilizer is the rolling-code type: the immobilizer communicates with the ECM using a different code each time the ignition switch is turned on – a complex signalling system that makes for a highly effective theft prevention measure.

Styling

• Concept: A lightweight and compact styling design created with the development goal of delivering, just like the engine and chassis, a truly state-of-the-art racetrack performance. While inheriting the highly popular styling themes of current and previous models, the latest model embodies further refinements that heighten its functionality. Styling highlights inherited from previous models, such as the rear view-mirror-integrated turn signals and the vertically-stacked dual headlights. Further refinements to realize a more compact, lightweight and functional styling design to help make the latest GSX-R750 more functional not only on racetracks but in a variety of riding situations.
• Compact Bodywork: The front overhang is reduced by 55mm, while the rear overhang is reduced by 35mm. Use of a more compact muffler.
• Lighter: While pursuing further aerodynamic refinement, the new bodywork is much lighter, realizing a 3,400gram (35 percent) weight reduction for the plastic bodywork components by reducing the number of parts (eight less parts), reducing overlapping sections, etc.
• More Functional: A relatively low 810mm seat height. Seat and surrounding sections designed to allow rider much freedom of movement. Side-panel centre section shaped with added parts to improve the airflow. A combination of smooth curved sections and sharp, edgy sections creates a trim, functional form.
• External Components: The front cowling is designed to provide effective wind protection while pursuing compactness and light weight. The design, aimed at keeping the frontal area as much as possible to reduce weight, maintains a favourable CdA (aerodynamic) figure and high wind-protection performance.
• Lower Cowling: The compact and lightweight lower cowling helps smooth the airflow toward the muffler cover.
• Fuel Tank: The newly designed fuel tank has the top lowered, to make the shape more convenient for the rider to tuck-in on racetracks. Fuel capacity is 17 litres. The tank cover is reshaped for a fresh new styling image.
• Headlights: The latest model inherits the vertically stacked dual headlights layout, the trademark of the GSX-R series. Designed for both aerodynamic refinement and light weight, the headlights now weigh 1,338 grams instead of the current model’s 1,900 grams, a weight reduction of 562 grams. The headlights deliver ample light distribution with a 12-volt 55-watt low-beam, 12-volt 65-watt high beam and two 12-volt 5-watt position lights.
• Turn Signals: The latest model inherits the characteristic rear view-mirror-mounted turn signals.
• Rear Combination Lamps: The LED combination lamp is built into the tail section that’s slim-styled and thin-shaped. The rear turn signals are shaped to wrap around well onto the top of the seat cowling, accentuating the impression of the tail section sweeping up rearward to a minimum-sized tail end.
