Simple, compact and light, the centrifugally operated, the SR-VVT system is built into the intake cam sprocket and an adjacent guide plate.

It uses 12 steel balls and slanted grooves to rotate the sprocket and retard the intake valve timing at a pre-set rpm, adding significantly to high-rpm power without sacrificing mid-range and lower-rpm power. The beauty of the SR-VVT system is in its compact simplicity, light weight, reliability and seamless operation. Moreover, the system is built into existing parts, taking up no extra room in the engine, and the weight increase is minimal.

For the 40th Anniversary GSX-R1000R, the VVT sprocket shape was changed in conjunction with the adoption of a wider new cam chain.

The camshaft intake and exhaust lift curves were optimized to achieve both the development goal for engine output and compliance with Euro 5+ emissions regulations. The maximum lift has not been changed, but the overlap has been reduced. In addition, the wider new cam chain helps reduce friction loss, (assuming use of low viscosity oil in races and endurance races), and the cam sprockets have been reshaped accordingly.

The GSX-R1000R uses thin-wall, hollow camshafts operating light, F1-style pivoting finger followers. The lighter moving mass of these fingers allows maximum engine rpm and valve lift to be increased while improving valve response and maintaining accurate valve control. Each finger follower in the GSX-R1000R has a DLC coating to increase durability.

The shape of the fingers on both the intake and exhaust sides was changed and optimized to match the new cam profile. In addition, the exhaust valve diameter was changed from 24 mm to 25 mm, increasing exhaust efficiency and thereby contributing to increased intake air efficiency.

One primary injector mounted at a steep angle in each throttle body operates full-time when the engine is running. A second injector that operates at higher rpm — also known as a Top Feed Injector (TFI) — is mounted in the top of the air cleaner box, directly over each throttle body’s intake funnel. The TFI injector delivers additional fuel in an improved spray pattern designed to enhance combustion efficiency, throttle response and top-end power.

The new injector positioned in each throttle body replaces the previous ten-hole design with an eight-hole design, the new injectors help achieve compliance with Euro 5+ emissions standards. Additionally, the fuel pump was changed to increase fuel pressure.

Electronic throttle bodies help achieve the right balance between idling speed control and power output characteristics, while their design also contributes to complying with Euro 5+ emissions standards.

The new 40th Anniversary GSX-R1000R throttle bodies are light and compact, with a larger bore (48 mm versus 46 mm) that helps enhance engine output. Each one has a single butterfly valve controlled by an advanced electronic engine management system, and each cylinder is fed by two ultra-fine-atomization eight-hole injectors.

Air is delivered to the throttle bodies via new single-stage funnels (velocity stacks). The funnel’s shape was a changed to contribute to improved output at high rpm.

Each forged aluminium piston has short skirts, cutaway sides and a short, DLC coated wrist pin to reduce friction. The compression ratio is 13.8:1.

The new piston heads were reshaped to increase the compression ratio and accommodate the size of the increased exhaust valve diameter. The rib shape on the underside of the piston heads was changed. This reduces weight by 3 grams and, as high-rotation parts, delivers benefits in output, vibration, and durability. In addition, the piston circlips are made of a new material that improves durability.

An L-shaped upper compression ring is pushed out against the cylinder wall by combustion pressure, limiting blow-by and maximizing cylinder sealing. The oil ring features a chrome-nitride coating. Harder and smoother than chrome plating, this chrome-nitride coating helps reduce friction, increase durability and enhance cylinder sealing.

The pistons are carried by chrome-molybdenum steel connecting rods with a carburized surface treatment to increase strength. The connecting rods are, manufactured to design standards with rigorous tolerances to enhance reliability as a race-based motorcycle.

The shot-blasted titanium muffler features a slim and stylish design that reflects the model’s tough image.

A number of updates were applied to the 4-2-1 exhaust system. Enlarging the diameter of the exhaust pipe contributes to maintaining output while complying with Euro 5+ emissions regulations.

In conjunction, a larger capacity elliptical (“racetrack-shaped”) catalytic converter in the collector is positioned closer to the engine to facilitate quicker warming, which helps improve its performance. A pair of O₂ sensors positioned in front and behind the catalytic converter help in complying with Euro 5+ emissions regulations.

Another benefit of the new layout is that it realized the design freedom to make the muffler body more compact, reducing its capacity from 8.3 to 5.5 liters while still retaining performance on par with the previous design.

The assist function leverages precision-engineered ramps to force the clutch boss and pressure plate together and efficiently transfer torque to the rear wheel under acceleration, all while using softer clutch springs. One benefit is a light touch to clutch lever operation that reduces fatigue of the left hand in situations that require frequent clutch lever operation.

The slipper clutch partially disengages when downshifting to decelerate to mitigate the effect of engine braking. By helping to prevent the rear tire from hopping and providing smoother deceleration, this function enables the rider to shift down with greater confidence and maintain better control.

SCAS works harmoniously with the Bi-directional Quick Shift system to deliver an additional benefit to the system’s clutch-free shifting.

New winglets added to the front cowling direct airflow and generate downforce at high speeds to enhance stability.

Made of dry carbon produced in Japan, the size and shape of the winglets was developed through a long process of experimental builds and thorough test runs to achieve the optimum lift effect without making handling feel heavy.

The core material upon which the winglets are formed has the characteristic of burning out after sintering, thus realizing the finished part’s hollow structure. The quality stands head and shoulders above wet carbon products, which are generally made from relatively inexpensive GFRP products with carbon attached.

These winglets adopt the same basic design as those used by Team Suzuki CN Challenge when competing in the Suzuka 8 Hours Endurance Race 2024.

Compact, light and rigid, the twin-spar aluminium frame is built to deliver nimble handling and great road holding ability.

Braced on both sides, the sturdy aluminium swingarm contributes to great road holding ability and provides the strength to withstand the demands of sporty runs on the road or the track.

The lightweight, six-spoke cast aluminium wheels contribute to positive handling and sporty performance.

They are shod with the latest generation of Bridgestone BATTLAX RACING STREET RS11 radial tires (120/70ZR17M/C (58W) at the front; 190/55ZR17M/C (75W) at the rear), have which earned a good reputation worldwide for delivering consistent performance and durability across a wide range of ambient conditions.

The GSX-R1000R uses radial-mount Brembo monoblock front brake callipers. Each calliper has four opposed ø32mm pistons acting on a ø320mm floating-mount disc for strong stopping power. A single hydraulic disc provides stopping power to the rear wheel.

Each disc features a hybrid mounting system using a 50/50 combination of 5 spring-loaded floating pin mounts and 5 Brembo T-drive floating mounts.  The T-drive mounts are lighter than spring-loaded floating pin.

Brembo T-drive discs can produce an audible rattle under certain conditions. Spring-loaded pin mounts are slightly heavier and produce a smaller contact area but are quieter. Using a combination of T-drive and pin mounts reduces rattle and requires fewer mounting points.

The electronically controlled steering damper automatically increases damping at higher speeds and reduces it at slower speeds. The result is a fine balance of precision and agility on faster and slower sections of the racetrack.

To further enhance the 40th Anniversary GSX-R1000R the  following updates were also made:

• The ABS unit has been changed to Astemo’s latest product, which is more compact and lighter, reducing weight by 51g over the unit on the previous model. The fairing’s under cowl was reshaped on both the left and right sides to match the new muffler layout. The changes include enlarging the notch on the right side and eliminating the hole on the left side.
• The fuel tank cap was changed to black and the O-ring was changed.
• The shape of the license plate lamp housing and rear fender behind the license plate has been changed from a square shape to a round one that makes the appearance of the tail cleaner and more appealing.
• The rear side reflectors have been changed from round to square for a cleaner look
• The projection profile of the pillion footrest was changed.

Suzuki Intelligent Ride System (S.I.R.S.)

Electric Equipment

•NEW Lightweight lithium-ion battery (HYbattEliiy P-series) improves voltage stability and reduces overall weight. Developed and manufactured by Eliiy Power in Japan.
•LCD multifunction display provides a clear, race-style information layout.
•Compact LED headlight contributes to sleek front-end styling.
• LED tail/brake light features a sharp vertical design.
• Bright LED indicators complete the premium lighting package.

The rider can select between three modes that deliver different power characteristics to match the conditions of the riding scene, surface conditions, or preferred riding style for any given outing.

The effect is particularly noticeable when turning the throttle grip between a slightly open position to when it reaches the top of the mid-speed range under acceleration.

The settings for each mode have been updated and thoroughly tested to perform optimally on the new GSX-R1000R, maximizing its capabilities, building in the flexibility to adapt well to changing weather, road and riding conditions, and making the overall riding experience more enjoyable.

A (Active) mode provides the sharpest response as the throttle is opened. Tuned to deliver exciting acceleration and fully leverage the engine’s power, it is well suited for enjoying aggressive runs on good pavement.

B (Basic) mode reaches the same level of maximum output but features a more linear curve with softer throttle response. The aim is to deliver a satisfying balance of settings that make a good fit for a broad range of riding styles and road conditions.

C (Comfort) mode aims to prioritize comfort and controllability by offering the softest throttle response and more gentle torque characteristics. This setting is a good choice when taking a long ride or heading home after a good afternoon’s ride.

The Smart TLR Control consists of:

1. Suzuki Traction Control System
2. Lift Limiter
3. Roll Torque Control

Suzuki Traction Control System

Designed to provide greater stability and enable the rider to control the GSX-R1000R with confidence in varying riding conditions while experiencing less stress or fatigue, this system features smooth control that does not interfere when enjoying a more aggressive, sporty ride. It offers 10 mode settings and can also be turned off.

The higher number the mode, the faster the control takes effect and the more proactive the system is in limiting wheel spin. In addition to monitoring front and rear wheel speed, engine RPM (as calculated using data from the crank position sensor), throttle position and gear position, the system uses data from the inertial measurement unit (IMU) to constantly monitor the amount of lean angle as well.

When the system determines an imminent loss of traction, the ECM controls output to the electronic throttle valve, ignition coil and spark plugs to limit power and prevent slipping. This technology is adopted directly from the traction control system Suzuki developed for racing.

The TC indicator on the instrument cluster flashes when the system is operating.

Note: The Suzuki Traction Control System is not a substitute for the rider’s throttle control. It cannot prevent loss of traction due to excessive speed when entering turns, or while braking. Nor can it prevent the front wheel from losing traction.

(NEW) Lift Limiter 

The 40th Anniversary GSX-R1000R now features Lift Limiter control which brings added peace of mind to riders by helping prevent the front wheel from lifting off the ground when accelerating. Lift Limiter works silently in the background, with its settings being determined by the Suzuki Traction Control (STCS) level setting.

In addition to monitoring engine RPM (as calculated using data from the crank position sensor), the GSX-R1000R’s ECM monitors throttle position, gear position and clutch switch status, and processes that data along with input from the front and rear wheel speed sensors and the Bosch IMU to determine the appropriate amount of output to developer in response to operation of the electronic throttle control.

Keen attention to detail and thorough testing went into tuning the respective settings for this intelligent control scheme to provide the benefit of acceleration expected of a GSX-R series motorcycle. This ranges from allow setting the prioritizes performance to a high setting that takes effect before the front wheel begins to lift.

Roll Torque Control (NEW)

Roll Torque Control is an intelligent system that, based on data received from the Bosch IMU and wheel speed sensors, calculates the bike’s lean angle and speed to predetermine what level of power output is optimal for a given corner. It works in conjunction with traction control to help deliver a sense of stability through the corner.

Launch control has also been updated to further improve its control scheme.

This system makes it easier for a racer to get a good start in closed-course competition by automatically limiting engine rpm and optimising torque delivery while the rider holds the throttle twist grip wide open and concentrates on feeding in the clutch lever.

Launch control is activated using a switch on the right handlebar. The system then monitors throttle twist grip position, throttle valve position, engine rpm, gear position, front wheel speed and rear wheel speed.

At the moment of launch, the system is set to hold the engine at ideal rpm for an effective launch. Once the clutch lever is released and the clutch engaged, rpm is no longer limited but throttle opening is controlled to keep the engine at the ideal torque for strong acceleration.

The launch control system not only helps the rider get a good initial launch, but also helps reduce the chance that a wheelie off the starting grid will require the rider to close the throttle twist grip. It does so by working with the Lift Limiter function and controlling engine torque while monitoring input from several sensors.
The launch control system automatically disengages when the rider upshifts into third gear or closes the throttle grip.

The Bi-directional Quick Shift System enables the rider to shift up or down without operating the clutch lever or throttle. As an added bonus, the system allows for the shifter to work in ‘race pattern’.

The system automatically interrupts power delivery just long enough — between 50 and 75 milliseconds depending upon the sensitivity adjustment — to unload the transmission gear dogs and allow a clean upshift, producing smoother, almost uninterrupted acceleration.

For quicker and smoother downshifts, the system automatically opens the throttle valves just enough to increase rpm and match engine speed to the next-lower gear ratio without manually blipping the throttle or using the clutch. This hands-free automatic blipping function combines seamlessly with engine braking to create a highly satisfying experience.

While the ECM is programmed to control the electronic throttle valves and ignition timing to match the engine’s operating speed and enable smooth shifting at any RPM, the gear shifting mechanism is optimized to provide a solid click with each shift that assures the rider a satisfying feeling that the gearbox has responded immediately to their action.

This system enhances control by allowing ABS activation not only when travelling in a straight line, but also when leaning into a corner.

The ABS unit’s ECU determines when intervention is called for by monitoring input from the front and rear wheel speed sensors along with vehicle posture data from the IMU. When it is, the ABS unit’s hydraulic unit controls brake pressure to reduce the impact of sudden braking force, making the bike less likely to try to push itself upright or lose traction.

As a result, the bike maintains its radius and lean angle, helping to support the rider in tracing their intended line through the corner. Even if the rider panics and brakes heavily in a corner, the system assists in maintaining stability while slowing the machine. The Motion Track Brake System supports sure and confident braking in various riding situations, both when riding straight and when cornering.

Note: ABS is not designed to shorten the braking distance. Please always ride at a safe speed for road and weather conditions, including while cornering.

This system helps prevent rear wheel lift when braking while riding downhill, resulting in a more stable ride.

The ABS unit uses input from the IMU to monitor the bike’s posture and, when the rider applies the brakes, its hydraulic unit controls brake pressure to deliver the optimum setting to match the angle of inclination.

The amount of rear lift control is continuously adjusted to match the current slope angle, and this results in supporting more stable braking.

This system lets the rider start the motorcycle with one quick press of the starter button.

There is no need to pull in the clutch lever when the transmission is in neutral, and the starter motor automatically disengages the instant the engine fires up. As a function used every time the engine is started, removing the bother of the above operations makes the riding experience more pleasurable and convenient.

Suzuki’s Low RPM Assist function monitors engine rpm, gear position, throttle position, and clutch switch data as the rider releases the clutch lever to pull away from a standing start, or when riding at low speeds. It is programmed to help prevent engine speed from dropping excessively as the rider launches the bike to ensure smoother starts. It also promotes more confident riding by helping counteract drops in engine speed when riding in stop-and-go traffic, or when doing U-turns.

Inertial Measurement Unit (IMU)

The GSX-R1000R adopts the latest version of Bosch’s IMU to track pitch, roll, and yaw movement in six directions along  three axes and constantly monitor the bike’s angular rate and acceleration. This real-time data is in turn employed to realize the precise and effective control provided by a number of advanced S.I.R.S features, including Lift Limiter, Roll Torque Control, the Motion Track Brake System and Slope Dependent Control. The new IMU reduces weight by approximately 10 grams over the previous generation.

Controller Area Network (CAN bus)

The GSX-R1000R employs a robust CAN bus that reduces the number of wires required by the harness, so contributes to reducing weight. The capabilities it brings to the table help realize the inclusion of advanced control systems. For example, while conventional ABS is controlled using only information from the front and rear wheel speed sensors, ABS on the GSX-R1000R also receives data from the IMU via the CAN bus to realize the Motion Track Brake system.

Engine Control Module (ECM)

The ECM provides state-of-the-art engine management that contributes to the operation and optimization of several critical systems.
