fuel-injected engine uses dual overhead cams and delivers extra-smooth acceleration.The 6-speed transmission has carefully selected gear ratios for strong acceleration and relaxed highway cruisingA maintenance-free secondary balancer shaft produces smooth engine operation.Suzuki Dual Throttle Valve (SDTV)-equipped fuel injection brings better response feel, smoother power output, and reduced emissions.Cylinder bores are finished with long-wearing Suzuki Composite Electrochemical Material (SCEM), just like the GSX-R sportbikes, for excellent heat transfer.A chrome-nitride coating, applied to each pistons upper compression and oil control rings using a physical vapor deposition (PVD) vacuum chamber system, is harder and smoother than conventional chrome plating, resulting in reduced friction and precise cylinder sealing.Liquid-cooled oil cooler augments the aluminum radiator to help keep the engine running cool.
