Suzuki GSX-R750 – the most powerful, efficient and clean-running 750cc four-stroke production engine it has ever produced, supported by a new cast-aluminum-alloy frame. New bodywork has improved aerodynamics, and the advanced engine management and fuel-injection system has adjustable on-the-fly mapping, as first seen on the GSX-R1000. The GSX-R750 also features revised, fully adjustable high-perform¬ance suspension and radial-mount brakes, as well as an electronically controlled steering damper that uses a solenoid valve to move a tapered needle, reducing or increasing oil flow to adjust damping force. The GSX-R600 gets a similar raft of changes, including the S-DMS engine-management system that allows the rider to choose from three engine settings to match riding conditions with a handlebar-mounted switch.
