ENGINE

• The powerful, 1,340cc, inline-four-cylinder, liquid-cooled, DOHC engine has been fully revised to supply a seamless surge of torque for effortless acceleration.
• Using techniques developed for the GSX-R1000, the redesigned crankcases have new lubrication passages for 54% more oil flow to the crankshaft for increased durability.
• The crankcase assembly hardware and tightening procedure is also revised to increase engine rigidity and durability.
• U-shaped cutouts in cylinder’s bores allow crankcase pressure created by descending pistons to escape to adjacent cylinders to reduce internal pumping pressure and mechanical power losses.
• Suzuki Composite Electrochemical Material (SCEM) cylinder coating improves heat dissipation, durability, and ring seal. The three-ring, aluminum-alloy slipper pistons have a new shape and lightweight design (reducing the weight of each piston by 26 grams). Conical machining at the piston pin bores improves strength and durability.
• The chrome nitride Physical Vapor Deposition (PVD) piston ring coating is harder and smoother than conventional chrome plating, reducing friction while improving sealing to the SCEM-coated cylinder.
• Like the crankcase, the crankshaft has been revised with new oil passages to increase lubrication at several key areas.
• The connecting rods have a new design that reduces weight (by 3 grams each rod) while increasing rigidity.
• The combined, lighter weight of the new crankshaft, connecting rods and pistons reduce internal vibration, which in turn contributes to greater engine durability.
• A gear-driven balancer shaft is timed to the crankshaft to help minimize vibration to the engine and the rider.
• The design of the Twin Swirl Combustion Chamber (TSCC) in the cylinder head is changed to promote faster and more efficient burning of the fuel-air mixture. The change complements other valve train updates, increasing flow coefficient by 5% to improve combustion efficiency.
• The exhaust camshaft’s lift has been increased and timing for both camshafts has been updated to reduce valve opening overlap, boosting low- to mid-range engine performance. Camshaft’s lobe width is increased, improving valve train lubrication and durability.
• Lightweight titanium valves with new, higher rate valve springs match the camshaft changes to maintain accurate valve control.
• The cam chain tensioner was redesigned to minimize chain runout and includes a new Teflon coating on the slipper surface to reduce mechanical loss.
• Fired by independent ignition coil-caps in each cylinder, iridium spark plugs produce more complete combustion and last longer than conventional plugs.
• A curved radiator with a compact, dense-core design and two ECM-controlled electric fans keep the engine temperature stable.
• Changes to the Hayabusa’s body permits higher air flow through the radiator, increasing cooling efficiency. The air flow is increased by 8% when the Hayabusa is in motion and approximately 7% when the cooling fan is moving air during low- to mid-speed riding.
• To allow the cooling fans to spin down when stopping in traffic, reducing warm air flow to the rider, the cooling fan blade pitch is improved and the fan shroud size is reduced.
• Positioned below the main radiator, a large-capacity air-cooled oil cooler reduces engine oil temperatures throughout the crankcase.
• The Hayabusa is now equipped with Suzuki’s Ride-by-Wire Electronic Throttle body system which provides a light, natural response with linear control similar to that of a conventional throttle.
• The electronic throttle bodies have tapered 43mm bores and are part of a new intake system (intake pipe, throttle body and air cleaner funnel) that is 12mm longer than the prior generation Hayabusa to boost power at low-to mid-range engine speeds.
• Because the ECM controls the action of the throttle bodies, other functions are added or improved; including cruise control, launch and lift control, the bi-directional quick shift system, cold-start up and idle speed control, and simplified service procedures.
• The new throttle bodies incorporate four primary fuel injectors that spray a fine mist of fuel directly into the intake pipes. Four additional Suzuki Side Feed Injectors (S-SFI) are set above the throttle body in the side of the intake funnels. These side injectors spray a fine mist of fuel on a reflecting plate at the top of the throttle body, resulting in a 2% increase in power and torque output in the low- to mid-range.
• The new throttle bodies made it possible to increase the air cleaner assembly’s capacity from 10.3 liters to 11.5 liters, increasing the air supply to the engine. The air cleaner has a more rigid lid and simplified internal structure that also enhances the intake air sound quality.
• The two Suzuki Ram Air Direct (SRAD) intake ducts in the upper fairing route high-pressure, fresh air to the air cleaner boosting performance in a linear fashion as the road speed increases.
• Flow analysis was employed when developing the SRAD ducts on the new Hayabusa. The new design reduces pressure loss and increases the flow of pressurized air to the air cleaner while contributing to smoother aerodynamics and a more exciting intake sound.
• Suzuki Pulsed Secondary Air Injection (PAIR) system introduces fresh air into the exhaust to ignite unburned hydrocarbons (HC) to reduce carbon monoxide (CO) emissions.
• The exhaust system is a fresh design that is 4.5 pounds (2,054 grams) lighter with newly styled silencers that complement the Hayabusa’s look. The silencers also have more capacity for better performance and have been tuned to emit a more exciting sound off idle and at lower speeds.
• The new four-into-two-into-one-into-two exhaust system configuration uses a new pipe connecting the #1 and #4 head pipes to help deliver more power and torque at low- to mid-range speeds. Like the prior generation exhaust, a connector pipe connects the #2 and #3 head pipes for similar benefits.
• The new exhaust has high-flow catalyzers in the mid-pipe and within each silencer to further reduce HC, CO, and nitrogen oxide (NOx) emissions. Dual O2 sensors provide instantaneous feedback to the ECM for smooth, clean EFI operation.
• The body of the exhaust silencers (mufflers) will change in color and hue over time in response to the way the bike is ridden. This makes it possible for each rider to add a unique personal touch to his or her Hayabusa.

Electrical & Lighting Features

• Riders adore the outstanding functionality and familiar layout of the Hayabusa’s instantly recognizable instrument cluster. Continuing the tradition of blending analog gauges with digital LCD displays and LED icons, the new Hayabusa’s instrument cluster benefits from a number of carefully developed improvements and valuable features with styling to match the bike’s modern appearance.
• An exceptional new feature of the instrument cluster is the TFT LCD panel centrally mounted between the speedometer and tachometer. By using two display methodologies, the TFT LCD panel can display a variety of information in formats that are easily recognizable and attractive.
• An ambient light sensor automatically adjusts the instrument cluster’s brightness level based on surrounding conditions, but the rider can manually adjust the illumination to their preference.
• Newly designed handlebar switches are laid out to maximize operating ease and efficiency. The mode/set switch on the left handlebar controls various Suzuki Intelligent Ride System (S.I.R.S.) settings and adjustments, including cruise control operation.
• A new dual-core 32-bit ECM provides state-of-the-art engine management that contributes to the operation and optimization of the Hayabusa’s electrical and S.I.R.S. components.
• Key to the operation of Hayabusa’s S.I.R.S. and other electrical features is a Computer Area Network (CAN) style wire harness that functions as an interconnected information network rather than using a more complex and slower conventional wiring harness.
• The 400W charging system uses a durable, oil-cooled three-phase stator. A high-capacity, maintenance-free style battery and fuses are easily accessible under the rider’s seat.
• Another component supporting S.I.R.S. and other Hayabusa technology is a new six-direction, three-axis Inertial Measurement Unit (IMU) supplied by Bosch.
• The Hayabusa is equipped with the latest compact Antilock Brake System (ABS) unit from Bosch. Working in conjunction with the new IMU, the ABS-unit realizes features such as the Motion Track Brake System, Slope Dependent Control System and Hill Hold Control System.
• Befitting its premium sportbike status, the new Hayabusa is equipped with highly functional and attractive lighting. The stacked headlight format that debuted with the original Hayabusa continues in this new generation with advanced technology and modern styling.
• Hayabusa’s front turn signals are incorporated in the position lights, a first for a Suzuki motorcycle.
• The bold new LED taillight and rear turn signal design creates a single wide, sharp accent running horizontally across the bottom of the Hayabusa’s tail section.

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

• CONTROL OF THE ENGINE OUTPUT CHARACTERISTICS: The Suzuki Drive Mode Selector Alpha (SDMS-α) system provides the rider a choice of three factory preset and three rider (or user) defined and combined settings of the Power Mode Selector, Motion Track Traction Control, Anti-lift Control, Engine Brake Control and Bi-directional Quick Shift systems.
• CONTROL OF THE ENGINE OUTPUT CHARACTERISTICS: The Power Mode Selector (PW) permits selection between three different engine output characteristic modes to match the riding conditions or the rider’s preference.
• CONTROL OF THE ENGINE ACCELERATION CHARACTERISTICS: The Motion Track Traction Control System (TC) was designed to provide greater stability and help enable the rider to control the Hayabusa with confidence in varying riding conditions by limiting rear wheel spin.
• CONTROL OF THE ENGINE ACCELERATION CHARACTERISTICS: The Anti-lift Control System (LF) adds control reassurance to riders by helping prevent the front wheel from lifting off the ground when accelerating.
• CONTROL OF THE ENGINE ACCELERATION CHARACTERISTICS: The Launch Control System (LC) helps ensure efficient launch and acceleration from a standing start. Launch Control for the Hayabusa offers three modes from which the rider can choose to match his or her level of experience or confidence.
• CONTROL OF THE ENGINE DECELERATION CHARACTERISTICS: The Engine Brake Control System (EB) is a new three mode (and OFF setting) system that provides control over the effective strength of engine braking to match the rider’s preference.
• CONTROL OVER THE ENGINE AT STEADY SPEEDS: The Hayabusa’s Cruise Control System maintains the selected road speed without the rider having to hold the throttle open – a welcome feature for long-distance riding that can reduce rider fatigue.
• CONTROL OVER THE ENGINE AT STEADY SPEEDS: Suzuki’s Active Speed Limiter is a first in the motorcycle industry, as this highly practical system allows the rider to set a speed limit the bike will not exceed, eliminating concerns about speeding or driving faster than intended.
• CONTROL OVER ENGINE OPERATIONS: The dual mode Bi-directional Quick Shift System (QS) allows the rider to shift up or down quickly and easily, without operating the clutch or throttle. To ensure smooth upshifts QS adjust ignition timing when accelerating or riding at a steady speed. When decelerating, QS adjusts throttle settings, automatically blipping the throttle when downshifting.
• CONTROL OVER ENGINE OPERATIONS: The Suzuki Easy Start System lets the rider start the motorcycle with a momentary 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.
• CONTROL OVER ENGINE OPERATIONS: The Low RPM Assist System seamlessly increases engine speed to smooth the power delivery when launching from a standing start or riding at low speeds to help ensure better control and operation in stop-and-go traffic. The system also minimizes the possibility of the rider stalling the motorcycle during take-off.
• CONTROL OVER BRAKING: The Combined Brake System provides stopping confidence to the Hayabusa rider as operating the front brake lever provides braking power to both the front and rear brakes.
• CONTROL OVER BRAKING: The Motion Track Anti-lock Brake System (MT-ABS) combines IMU-measured, spatial information of the Hayabusa’s posture in conjunction with front and rear wheel speeds. This allows the ABS** to not only activate in a straight line but also when the vehicle is leaning or turning.
• CONTROL OVER BRAKING: The Slope Dependent Control System prevents rear wheel lift when braking when travelling downhill. The ABS unit continually measures brake pressure while the IMU constantly monitors vehicle posture of the vehicle even as the Hayabusa is traveling downhill. When the rider operates a brake lever or pedal when riding downhill, the electronic control unit adjusts brake pressure to prevent rear wheel lift, providing more stable braking.
• CONTROL OVER BRAKING: The Hill Hold Control System helps hold the Hayabusa when it is stopped on an incline, providing confidence so riders can focus on smoother takeoffs up the hill.
