Engine Features
Electronic fuel injection system features Suzuki Dual Throttle Valve (SDTV) system - with dual fuel injectors per cylinder and new compact 8 hole, fine spray injectors for improved fuel atomization.
S-DMS engine management system allows the rider to choose from three engine settings to match riding conditions with a handlebar mounted switch
Under deceleration the back torque limiting clutch reduces pressure on the clutch plates for smoother downshifting and corner entry
Aluminum clutch cover and oil pan feature internal ribs for increased rigidity and reduced engine noise
Suzuki Idle Speed Control (ISC) system for improved cold starting, consistent idle quality and reduced emissions
High volume Suzuki Advanced Exhaust System (SAES) with an innovative under engine chamber leading to a large volume muffler with a distinctly shaped triangular silencer
Hydraulic cam chain tensioner automatically adjusts while reducing noise and mechanical losses.
Ignition coil outer diameter is smaller for reduced weight and the starter motor uses new rare earth magnets for a compact lightweight design
32 bit ECM features 1024 kilobytes of ROM for maximum engine performance working in conjuction with the new S-DMS engine management system
Compact 4-stroke, 4-cylinder, liquid-cooled engine designed for optimum combustion efficiency and maximum power delivery
Cylinder head with narrow valve angles creating a compact combustion chamber design, 12.5:1 compression ratio, large intake and exhaust ports for optimum intake and exhaust efficiency and new Iridium spark plugs
Lightweight titanium valves with steel alloy springs and aluminum spring retainers operated by thin-wall hollow camshafts to reduce weight and inertia
Lightweight forged aluminum alloy pistons with short skirts, cut away sides and an anti-friction surface finish along with shotpeened chrome-moly steel connecting rods for improved strength
Crankshaft features forged steel construction and a secondary balancer shaft for reduced vibration at high rpm.
Crankshaft and transmission shafts are positioned to create a compact engine design and the engine itself is rotated slightly forward in the chassis allowing for straighter and shorter intake and exhaust ports
High capacity large trapezoidal-shaped radiator provide efficient engine cooling - includes compact cooling fan assembly designed for improved air flow
SRAD ( Suzuki Ram Air Direct) force feeds cool, pressurized air into the airbox at highway speeds, improving engine efficiency and throttle response
Chassis Features
The 2009 GSX-R750 features a sharp and aggressive look utilizing a bold new headlight design, angular tail section and compact overall layout
Electronically controlled steering damper uses a solenoid valve to move a tapered needle reducing or increasing oil flow to adjust damping force.
Lightweight cast aluminum wheels featuring an angled spoke design for improved rigidity, reduced unsprung weight and improved acceleration
Inverted 41mm Showa cartridge front forks are fully adjustable for high and low speed compression, spring preload, and rebound damping
