HAYABUSA

The Hayabusa's muscular 1340cc in-line four-cylinder engine delivers a broad wave of torque for effortless acceleration. Its advanced design boasts liquid-cooling, ram-air downdraft induction producing 145kW (195hp) @ 9,500rpm with 155Nm of torque @ 7,200rpm.

Forged three-ring aluminum-alloy slipper pistons provide superior strength. The oil control ring on each piston is electro-plated with a chrome-nitride coating applied in a vacuum chamber using a Physical Vapor Deposition (PVD) system. The chrome nitride PVD coating is harder and smoother than conventional chrome plating, reducing friction while improving cylinder sealing. The upper piston ring also features an L-shaped cross section, with combustion pressure pushing the ring tighter against the cylinder wall to further reduce blowby and increase the force actually pushing the piston down.

The Hayabusa features the unique Suzuki Drive Mode Selector (S-DMS) system, which allows the rider to select one of three engine control maps. The system allows the rider to select a different map to suit personal preferences in various riding conditions, such as choosing one map for highway cruising and another map for tighter roads.

The Hayabusa engine is fitted with tapered, 44mm double-barrel Suzuki Dual Throttle Valve (SDTV) throttle bodies. Unlike conventional fuel-injection systems, the SDTV system has two butterfly valves in each throttle body barrel. The rider controls the primary valve via a throttle grip, and the engine management system automatically controls the secondary valve, opening it incrementally to maintain optimum intake charge velocity based on engine rpm, gear position and primary valve opening. This precise, carefully controlled system improves combustion efficiency and makes throttle response feel more natural to the rider.

The Hayabusa design perfectly merges motorcycle and rider. Carefully sculpted bodywork tames the wind to maximize the more-than-ample power of the Hayabusa engine. Extensive wind tunnel testing with a rider onboard helped to find the ultimate shape for high-speed riding. The radical aerodynamic styling and smoother bodywork not only gives the Hayabusa its unique look but also protects the rider from the wind and improves fuel efficiency.

Lighter and more rigid than conventional bolt-together calipers, the Hayabusa's top-of-the-line radial-mount Brembo Monobloc front brake calipers deliver better feedback to the rider. The piston diameters were enlarged from 32-30mm to 32-32mm. Larger pistons help apply greater force to the brake disc, which results in increased initial bite and a more controlled feeling.

A new, standard equipment Antilock Brake System (ABS) unit features a lightweight, compact design. The ABS enhances brake performance by helping prevent, to a certain extent, wheel locking due to changes in road conditions or excessive braking, by matching stopping power to available traction. Note : The ABS is a supplemental device for brake operation, not a device for shortening stopping distance. Always remember to reduce speed sufficiently before approaching curves.

KYB inverted cartridge forks feature a Diamond-Like Carbon (DLC) coating surface treatment on the 43mm stanchion tubes to reduce friction and increase reaction to small surface irregularities. The forks provide front wheel travel of 120mm. Spring preload, compression damping and rebound damping are fully adjustable.

Lightweight titanium valves allow the use of light valve springs and high lift while maintaining accurate valve control.

An individual coil built into each spark plug cap and spark plugs with finer, Iridium-alloy electrodes produce a hotter spark and more complete combustion; the Iridium-alloy spark plugs have double the service life of conventional spark plugs.

The Hayabusa's instrument cluster features a set of four round analog gauges, including step-motor-driven tachometer and speedometer, fuel meter and coolant temperature meter. LEDs are used for a programmable engine-rpm indicator, a lowfuel-level warning light, a neutral indicator light, turn-signal indicator lights, a high-beam indicator light, a high coolant temperature warning light, a low oil pressure warning light and a fuel injection system warning light. A round, centered LCD information panel includes clock, gear position indicator, S-DMS map indicator, odometer and dual trip meter displays

Hayabusa is equipped with the Bridgestone BT-015, which is specially developed for the motorcycle. The tire's profile and compound were developed through a variety of testing to achieve a high level of stability and handling. A single-piston, pin-slide TOKICO rear brake caliper works with newly equipped ABS. The rear disc is 260mm in diameter and 5.5mm thick.
