Engine FeaturesCompact & lightweight 4-stroke, 4-cylinder, liquid-cooled engine designed for overall weight reduction, optimum combustion efficiency and 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 high power output
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 strenth
One-piece cylinder block and upper crankcase section is equipped with 39mm ventilation holes between cylinders to reduce crankcase pressure and mechanical loss
Tapered, 50mm double-barrel throttle body design features Suzuki’s SDTV throttle valve system, plus twin multi-hole-type injectors per cylinder for optimum performance and throttle response
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
New back torque limiting clutch allows smoother downshifts and works in conjuction with an updated six speed transmission with revised internal gear ratios and updated shift forks
Innovative new Suzuki Advanced Exhaust System (SAES) with new under engine muffler layout and Suzuki Exhaust Tuning (SET) system for maximum mass centralization, superior aerodynamics, and improved low-to-mid range performance
High capacity large trapezoidal-shaped radiator provide efficient engine cooling - includes compact cooling fan assembly designed for improved air flow
Suzuki Idle Speed Control (ISC) system improves cold starting and stabilizes engine idle speed in a variety of conditions.
SRAD ( Suzuki Ram Air Direct) force feeds cool, pressurized air into the airbox at highway speeds, improving engine effeciency and throttle response
Chassis Features
An ultra-lightweight frame is built entirely of aluminum alloy castings and is engineered to deliver optimium rigidity, unmatched accuracy and maximum cornering performance.
A braced aluminum alloy swingarm features a large 25mm swingarm pivot and is designed for optimum rider feel and maximum rear wheel traction
RM-Z450 inspired new 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
Inverted 41mm Showa cartridge front forks are fully adjustable for spring preload, compression damping, and rebound damping.
Showa rear shock absorber with a 46mm piston and a 16mm rod moves the same amount of oil despite a shorter stroke and provides adjustable rebound damping, preload as well as high and low speed compression damping settings
310mm brake discs work with radial mount calipers and radial front brake master cylinder.
Bridgestone radial tires are mounted on cast aluminum wheels featuring thin lightweight spokes with optimized wall thickness to reduce unsprung weight
Aggressive and aerodynamic bodywork gives the GSX-R750 a stylish look and when combined with integrated turn signals and smaller frontal area provide maximum aerodnamic effeciency
Compact, lightweight instrument cluster features a step motor controlled analog tachometer, LCD speedometer, dual trip meters, clock and a convenient gear position indicator
Riding position is optimized with a short fuel tank, lower seat height, and adjustable rider footpegs for improved rider control and mobility
