New Features

Redesigned instrument cluster now features four analog meters for speedometer, tachometer, fuel gauge and water temperature with a new S-DMS mode indicator, gear position indicator and adjustable engine rpm indicator.

New Engine
New 1340cc, DOHC liquid-cooled engine with 16-valves, Twin Swirl Combustion Chambers provides 11% higher performance and smoother operation
New Suzuki SDTV fuel injection system with dual injectors per cylinder and ram air intake with large volume airbox
New S-DMS (Suzuki Drive Mode Selector) allows the rider to choose from three different engine settings depending on riding conditions or rider preferences
New lightweight titanium intake and exhaust valves with narrow 14 degree valve angle for high combustion chamber efficiency
New lightweight aluminum alloy pistons feature a revised shape and a higher compression ratio of 12.5:1 for maximum performance in all conditions.
SCEM (Suzuki Composite Electro-chemical Material) plated cylinders minimize cylinder size and improve heat dissipation and new hydraulic cam chain tensioner for reduced mechanical noise
New ventilation holes at the cylinder skirt for reduced pumping losses and increased performance
High efficiency curved radiator now features dual electric fans controlled by the ECM for increased cooling capacity. Oil cooler now has 10 rows cores for increased heat dissipation.
New large volume 4-2-1-2 exhaust system with a large capacity catalyzer, dual triangular canisters and closed loop system that meets Euro 3 and Tier 2 regulations
New Shot-peened chrome-moly steel connecting rods for maximum durability
Ion plating treatment utilizing PVD (physical vapor deposit) method is applied to piston rings providing a smoother surface treatment for increased durability, reduced friction loss and reduced oil consumption
Slick shifting 6 speed transmission working in conjunction with an innovative back torque limiting clutch for smooth and controlled downshifts

New Chassis
All new aggressive aerodynamic fairing design with low drag coefficient retains it's signature Hayabusa look and features an updated, muscular look to work with the new more powerful engine and updated chassis
