Led by the 2023 Hayabusa, Suzuki’s landmark ultimate sportbike, this group of new motorcycles brings together a collection of proven Suzuki products including the flagship sport model, Hayabusa; the tried and true, go anywhere and do anything DualSports and SuperMoto of the DR line; and the championship-bred RM-Zs with an RM Army Edition that will have everyone looking.

The 2023 Suzuki Hayabusa reaffirms its status as motorcycling’s Ultimate Sportbike. This new generation of Suzuki’s flagship continues to be propelled by a muscular, refined inline four-cylinder engine housed in a proven and thoroughly updated chassis with incomparable manners, managed by an unequaled suite of electronic rider aids all housed within stunning aerodynamic bodywork that is distinctly Hayabusa.

Riders who have owned or longed for a Hayabusa will recognize the iconic, aerodynamic silhouette that has been refined through wind tunnel development, so the body features new vent shapes, air diffusers, and reimagined logos while a sophisticated LED lighting system achieves a new zenith of style and function.

Engine performance has been broadened so the Hayabusa accelerates quicker and smoother than ever before while complying with worldwide emissions standards. Rider control is expanded through Hayabusa’s Suzuki Intelligent Ride System (S.I.R.S.). The engine’s adjustable power delivery, traction control*, cruise control, launch control, Bi-directional quick shifter, and Motion Track ABS** and Combined Brake systems offer the Hayabusa rider unmatched options on how the ride will unfold.

The Hayabusa will come in three striking color combinations Pearl Vigor Blue/Pearl Brilliant White, Metallic Mat Black/Glass Sparkle Black, and a Metallic Thunder Gray/Candy Daring Red.

KEY FEATURES

• The Hayabusa is instantly recognizable as its wind-cheating body preserves the cues that were inspired by the peregrine falcon – the world’s fastest animal. To bring a sophisticated appearance to the iconic Hayabusa, Suzuki’s design team incorporated distinct lines and shapes to achieve an expression of refinement and ultimate performance.
• For 2023, riders may choose from three stunning color schemes: Metallic Matte Black & Glass Sparkle Black, Pearl Vigor Blue & Pearl Brilliant White, or Metallic Thunder Gray & Candy Darling Red. Each scheme features the iconic Hayabusa Kanji symbols and name logos.
• The Hayabusa’s legendary 1340cc, four-cylinder, DOHC engine is fed by Ride-by-Wire electronic throttle bodies with dual fuel injectors feeding each cylinder, mixing with pressurized air from the Suzuki Ram Air Direct (SRAD) intakes in the nose of the aerodynamic fairing. The symmetrical twin silencer exhaust system is lighter with better flow and a stimulating exhaust note.
• The Hayabusa’s superbike-caliber, twin-spar aluminum frame delivers a stable ride with nimble handling that can be personalized through the adjustable KYB-supplied suspension. Optimized aerodynamics and wind protection provide comfort while improved braking performance inspires rider confidence.
• The Hayabusa employs an advanced version of the Suzuki Intelligent Ride System (S.I.R.S.); a comprehensive collection of electronic rider aids like Cruise Control and Bi-directional Quick Shift systems that can optimize and personalize the motorcycle’s performance characteristics to match the conditions and desires of the rider. Only the Hayabusa offers this premium suite of aids that simultaneously boosts performance and comfort as riders enjoy the ultimate sportbike experience.

ENGINE FEATURES

• The powerful, 1,340cc, inline-four-cylinder, liquid-cooled, DOHC engine supplies a seamless surge of torque for effortless acceleration.
• Using techniques developed for the GSX-R1000, the crankcases have lubrication passages that provide 54% more oil flow to the crankshaft than the prior generation engine to help increase durability.
• Specialized crankcase assembly hardware and a modern tightening procedure is used 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 been shaped and reduced in weight (weight of each piston was reduced 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 high flow oil passages to increase lubrication at several key areas.
• The connecting rod design that reduces weight (by 3 grams each rod) from the prior generation part while also increasing rigidity.
• With lower mass than the prior generation parts, the 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 was updated in this generation engine to promote faster and more efficient burning of the fuel-air mixture. This update complements other valve train updates, increasing flow coefficient by 5% to improve combustion efficiency.
• The exhaust camshaft’s valve list is higher than the prior generation engine and the timing for both camshafts has been tuned to reduce valve opening overlap, boosting low- to mid-range engine performance. Wide camshaft’s lobes improve valve train lubrication and durability.
• Lightweight titanium valves with high-rate valve springs ideally match the camshafts to maintain accurate valve control.
• The cam chain tensioner design minimizes chain runout and uses a 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.
• The fairing design permits high air flow through the radiator, increasing cooling efficiency as compared to the prior generation Hayabusa. Air flow is increased by 8% when the Hayabusa is in motion and is approximately 7% better 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 has been optimized and matched to a smaller fan shroud.
• Positioned below the main radiator, a large-capacity air-cooled oil cooler reduces engine oil temperatures throughout the crankcase.
• The Hayabusa is equipped with Suzuki’s Ride-by-Wire Electronic Throttle body system which provides light, natural response with linear control like that of a conventional throttle.
• The electronic throttle bodies have tapered 43mm bores and are part of a high-flow 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 features can be precisely controlled, such as cruise control, launch and lift control, the bi-directional quick shift system, cold-start up and idle speed control, and simplified service procedures.
• The throttle bodies use 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 more compact 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 rigid lid with a simplified internal structure that 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.
• 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.
• 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 4.5 pounds (2,054 grams) lighter than the prior system with silencers styled to complement the Hayabusa’s overall 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 four-into-two-into-one-into-two exhaust system configuration uses connecting pipes from 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.

CHASSIS FEATURES

The Hayabusa’s twin-spar aluminum frame and swingarm incorporate aluminum castings along with extruded aluminum sections that provide the right amount of suppleness and strength to its overall rigid alloy frame structure.

Weighing 1.5 pounds (700 grams) less than the prior generation’s part, the redesigned sub-frame is made of longer rectangular steel tubing for ample weight-carrying capacity.

The KYB® inverted cartridge fork has a specific internal structure to provide more compliance, further improving the suspension’s ability to absorb shocks from the road helping to ensure a smoother, more stable ride with optimum grip.

The fork has spring preload plus rebound and compression damping force adjusters so the rider can tune the suspension response to their preference.

The fork’s 43mm inner tubes feature Diamond-Like Carbon (DLC) coating to reduce friction and improve reaction to small road surface irregularities.

Like the fork, the internal structure of the KYB® rear shock absorber was designed to help optimize comfort and straight-line stability.

The shock absorber has threaded spring preload adjustment collars plus rebound and compression damping force adjusters.

A steering damper attached to the frame and the lower fork bracket provide damping force to suppress unwanted vibration and steering forces, but are tuned to provide a light steering feel at lower speeds.

Seven-spoke cast aluminum alloy wheels are used to help improve grip and feel to the rider while matching the Hayabusa’s exciting styling.

Co-developed by Suzuki and Bridgestone®, the Hayabusa is shod with Battlax Hypersport S22 tires in120/70ZR17M/C (58W) front and 190/50ZR17M/C (73W) rear sizes.

These Bridgestone® tires use a compound and construction to help improve grip on dry roads, performance in wet conditions, and help provide greater all-round agility. The S22 tires also provide excellent straight-line stability and braking grip, providing the rider a more exciting and confidence-building experience.

The Hayabusa provides the rider extraordinary control of braking with the Combined Brake System, and the Motion Track Antilock Brake System (MT-ABS)**.

• With the Combined Brake System the rider can operate the brake with more confidence as operating the front brake lever will provide braking power to both the front and rear brakes.
• The advanced ABS-unit has a lightweight, compact design. Antilock brakes enhance braking performance by matching stopping power to available traction which helps prevent, to a certain extent, wheel locking due to changes in road conditions or excessive braking.
• This ABS-unit combines IMU-measured, spatial information of the motorcycle’s posture in conjunction with front and rear wheel speeds. This allows the MT-ABS** to not only activate in a straight line but also when the vehicle is leaning or turning.
• See other brake system-related features in the Suzuki Intelligent Ride System (S.I.R.S.) section.

The Hayabusa is equipped with the innovative Brembo® Stylema®& front brake calipers. Featuring a light, compact and carefully sculpted design that is intended for use on high-performance motorcycles, these calipers increase airflow around the brake pads to cool more quickly and deliver immediate response.

The Stylema® front brake calipers are paired with a pair of 320mm diameter stainless-steel full-floating discs with a hole pattern that further helps optimize cooling efficiency.

The solo rear 260mm brake rotor is grabbed by a single-piston brake caliper.

The floating handlebar mount helps minimize vibration, while the upper clamp incorporates a distinctive Hayabusa logo.

As compared to the prior generation Hayabusa, the handlebars are mounted 12mm closer to the rider vastly improving comfort and reduce fatigue when touring while enhancing control.

The rider footrests have damped mounting hardware to reduce vibration and are set in a sporty, yet comfortable relationship to the handlebars and seat. The heel guards incorporate replaceable plastic inserts that can be changed to renew their appearance.

Both the shift and rear brake levers are easily adjustable to the rider’s preference.

The Hayabusa’s black-anodized, adjustable clutch and front brake lever have carefully crafted shapes to aid rider control and feature slots at the ends to reduce the chance of wind pressure pushing the levers inward.

The bodywork and sub frame were designed to bring the Hayabusa’s seat height down to 31.5 inches.

The rear seat is set higher than the front seat so the passenger can enjoy a forward view over the rider’s shoulder.

Visually matching the Hayabusa’s styling, the grab rail is reshaped and set in proximity to the rear seat so it is easy for the passenger to grasp.

The passenger seat and grab rail can be replaced by an optional, color matched single seat cowl that acts as a lumbar stop for the rider during solo rides while adding to the Hayabusa’s performance-related style.
