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
• Radial mount four piston front brake calipers works with 310mm front brake rotors and a radial pump front brake master cylinder
• '09 GSX-R750 fuel tank features an innovative design and fuel capacity is 4.5 gallons
• The lightweight frame is built entirely of aluminum alloy castings and is engineered to deliver optimum rigidity, unmatched accuracy and maximum cornering performance.
• A braced aluminum alloy swingarm features a large 22mm swingarm pivot and is designed for optimum rider feel and maximum rear wheel traction
• Innovative rear suspension linkage utilizes a forged aluminum alloy link and a forged aluminum link rod that reduces side loads and helps the rear shock absorber move in a smooth arc
• Showa 41mm aluminum alloy rear shock with a 16mm rod diameter are fully adjustable for high and low speed compression, spring preload and rebound damping for maximum rider control
• Three way adjustable footpegs now feature die-cast construction and can be moved into three different positions with a 14mm horizontal and vertical range
• Compact, lightweight instrument cluster features a step motor controlled analog tachometer, LCD speedometer, dual trip meters, clock and a convenient gear position indicator
