Hayabusa

The sleek, aerodynamic silhouette is unmistakably that of the Hayabusa. But the modern look of its styling and luxurious attention to the finest details say it’s a whole lot more. True to its design concept, “The Refined Beast,” the Hayabusa’s long, low stance screams of the power, performance, poise and keen perceptive abilities possessed by a bird of prey.

Though the engine is already renowned for its durability and longevity, the following refinements aim to take it to another level. The pistons and connecting rods reduce the weight of moving parts within the engine. Changes to the crankshaft oil passages improve engine lubrication. The transmission shaft needle bearings are extended in length. Attention to detail goes as far as changing the way the engine case bolts are tightened, and even to the threading for the screw holes in the upper crankcase.

The pistons and Twin Swirl Combustion Chamber (TSCC) design fully leverage advances in CAE analysis to bring in more air as the valves begin to lift and thereby increase combustion efficiency. Suzuki Side Feed Injectors (S-SFI) feature a dual injector design that positions the secondary injector so its spray strikes a reflecting plate in the funnel and enters the combustion chamber as a fine mist. This combines with the increased capacity of an air cleaner and longer intake pipe design to optimize low- to mid-range power output and make the Hayabusa more controllable in typical daily riding situations.

Suzuki’s ride-by-wire throttle control system provides natural response with linear control, while a related change to a 43mm bore size for the throttle bodies boosts low- and mid-range power output. Also helping to improve performance and controllability at the most commonly used low- to mid-range speeds are the engine’s reduced valve lift overlap and a pipe on the exhaust header connecting cylinders #1 and #4.

The Hayabusa’s vertically stacked low beam and projector-type high beam headlights adopt LEDs. The distinctive signature of their lighting pattern provides clear illumination at night and makes the Hayabusa highly visible to pedestrians and other traffic. Position lights with integrated turn signals*, a first on a Suzuki motorcycle, neatly flank the outer edges of the large SRAD air intakes. In the rear, a bold LED taillight and rear turn signal design create a single wide, sharp accent running horizontally across the bottom of the tail section.

A 6-axis, Bosch IMU (Inertial Measurement Unit) combines accelerometers and gyroscopes in a single compact package that constantly monitors pitch (forward or backward tilt), roll (leaning from side to side), and yaw (turning in relation to initial direction). These measurements are compared against one another as well as readings from wheel speed sensors to keep the Hayabusa aware of its situation at all times and realize several of the advanced S.I.R.S. controls.

The Suzuki Hayabusa’s Lift Control System is designed to maximize acceleration performance while helping prevent the front wheel from lifting off the ground. When activated, the system offers 10 selectable modes, allowing riders to choose the level of intervention that best suits their preference.

Mode 1 provides minimal control, while Mode 10 delivers the highest level of intervention, making it virtually impossible to lift the front wheel even when fully opening the throttle with a passenger on the back.

The Suzuki Hayabusa’s Motion Track Traction Control System uses data from the IMU to continuously monitor lean angle and help limit wheel slip both in corners and on straightaways. By enhancing stability across varying riding conditions, the system helps provide more confident control while reducing rider stress and fatigue.

Riders can choose from 10 traction control settings or turn the system off when preferred. Higher-numbered modes engage traction control more quickly and take a more proactive approach to limiting wheel spin.

Note: The Motion Track Traction Control System is not a substitute for rider throttle control. It cannot prevent loss of traction caused by excessive speed when entering a turn and/or applying the brakes, nor can it prevent the front wheel from losing grip.

The Suzuki Hayabusa’s Launch Control system is designed to deliver efficient acceleration from a standing start, providing a launch experience similar to the way racers leave the starting line. Three selectable modes allow riders to match the engine speed at launch to their level of experience or confidence.

Mode 1 limits engine speed at launch to 4,000 rpm, Mode 2 operates at 6,000 rpm, and Mode 3 — the fastest setting — operates at 8,000 rpm.

The Suzuki Hayabusa’s cornering ABS combines vehicle posture data from the IMU with front and rear wheel speed sensor data to enable ABS activation not only while riding in a straight line, but also when leaning into a corner. This helps reduce the tendency for the motorcycle to stand upright or lose traction under braking, allowing it to better maintain its radius and lean angle while following the rider’s intended line through the corner.

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

The Suzuki Hayabusa’s downhill braking control system monitors the motorcycle’s posture and angle to help prevent rear wheel lift. Using ABS to control brake pressure, the system compensates when braking while travelling downhill to help maintain greater stability and control.

The Suzuki Hayabusa is equipped with Brembo Stylema® front brake calipers, designed for high-performance motorcycles. Their lighter, more compact and carefully sculpted design increases airflow around the brake pads, helping them cool more quickly while delivering immediate braking response.

The Brembo Stylema® calipers are paired with 320 mm front brake discs, increased from 310 mm, and feature a hole pattern that further helps optimize cooling efficiency.

Superior core strength

The Suzuki Hayabusa chassis is designed to provide sure footing, nimble handling and predictable control, helping build rider confidence and enhance the overall riding experience. It delivers a smooth, comfortable ride by absorbing irregularities in the road surface while responding faithfully to rider input. The chassis also helps transfer the abundant power of the Hayabusa’s legendary powerplant to the pavement, while fully leveraging its onboard intelligent control systems for effective acceleration and braking, whether barrelling down a straight section of road or leaning through corners.

At the heart of the Hayabusa chassis is its tried-and-true twin-spar aluminum frame and swingarm. During development, Suzuki built and track-tested a number of different prototype frames before retaining the proven combination of extruded aluminum sections and aluminum castings. This construction provides the right balance of suppleness and strength within the rigid alloy frame structure.

Although extruded aluminum sections are more costly and demanding to fabricate, they help achieve the overall balance required by a machine designed to deliver ultimate performance and reach a nominal top speed of 299 km/h. This same focus on strength, rigidity and weight balance is why extruded aluminum frame members can also be found on a number of supercars.
