Suzuki GSX-S750 2021 Features
KEY FEATURES New fuel injected, 749cc, four-cylinder engine uses GSX-R architecture to deliver a torque-rich sportbike experience. Suzuki Advanced Traction Control* lets the rider select sensitivity to match road conditions. Changes can be made on the fly so the rider can adapt the power delivery to changing conditions. The unique chassis integrates the best qualities of a tubular streetbike frame and a twin-spar sportbike frame, and is fitted with KYB suspension to provide precise handling. The front Nissin Monobloc, four-piston brake calipers and twin, wave-style brake rotors bring strong and consistent braking performance. Metallic Matte Black and Glass Sparkle Black paint scheme with aggressive blacked out styling surround an ergonomically comfortable yet sporty riding position.
ENGINE FEATURES Potent 749cc four-cylinder fuel injected engine uses 2005 Suzuki GSX-R750 architecture, so the power delivery is an excellent blend of strong low end and a muscular top end. Using the K5-generation GSX-R engine architecture also permits a shorter chassis, which greatly enhances handling. This also makes the Suzuki GSX-S750 the only motorcycle in its class with an engine with SuperSport lineage. Ventilation holes are machined into the bottom side of each cylinder in the Suzuki GSX-S750 crankcase. The holes reduce pumping loss to help produce power and gain fuel economy. Camshafts tuned specifically for the Suzuki GSX-S750 deliver a dynamic wave of smooth torque and strong acceleration. Throttle bodies with Suzuki Dual Throttle Valve (SDTV) system contribute to better throttle response and torque at the low- to mid-rpm range, while still producing peak performance. Ten-hole, long-nose fuel injectors deliver finer atomized fuel to increase combustion efficiency. Suzuki’s patented, Throttle-body Integrated Idle Speed Control (TI-ISC) stabilizes the engine idle speed and helps lower emissions. The system is compact and lightweight. The TI-ISC on the Suzuki GSX-S750 has Suzuki’s Low RPM Assist feature that seamlessly adjusts engine speed during takeoff and low-speed riding to smooth the power delivery and to help reduce the possibility of the rider stalling the motorcycle. A large-capacity airbox is required to match the higher engine output. The air inlets have been designed to provide an exciting auditory experience. The Engine Control Module (ECM) provides state-of-the-art engine management and has carefully developed settings to suit the intake and exhaust systems, resulting in linear throttle response and class-leading fuel economy. Suzuki’s Advanced Traction Control System* lets the Suzuki GSX-S750 rider control the throttle with more confidence in various riding conditions. As a result, the rider can enjoy sport riding with less anxiety. There are four traction control modes (1, 2, 3, and OFF) that the rider can easily adjust at rest or on the fly via a handlebar-mounted control. The difference between the modes are their sensitivity to road conditions.
Mode 1 is the lowest sensitivity level; most suitable for skilled riders or in conditions that have good road surface grip (sport riding on good, smooth roads).
Mode 2 is a moderate sensitivity level; suitable for most riders or in conditions that have varied road surface grip (city riding, regular road conditions).
Mode 3 is the highest sensitivity level; suitable for road conditions where the grip may be limited (wet or cold surfaces).
OFF disengages all traction control features.
The digital ignition fires iridium type spark plugs that increase spark strength and combustion efficiency, contributing to higher power, more linear throttle response, easier engine start-up, and a more stable idle. These quality components also last longer than conventional spark plugs. The stainless steel, 4-2-1 exhaust system helps the engine deliver a strong low- to mid-range punch with an exciting rush to redline. A larger catalyzer is in the mid-pipe to assist in emissions control without sacrificing performance. Angular radiator shrouds efficiently guide cooling air to the high-capacity radiator. Additional heat is removed from the engine via the use of a lightweight and compact liquid-cooled oil cooler (like those used on GSX-R600 and 750 models).
TRANSMISSION FEATURES The race-proven, six-speed, close-ratio transmission features vertically staggered shafts to reduce overall engine length. The shorter, final gear ratio enables the Suzuki GSX-S750 to accelerate quicker than the prior model while the additional engine power maintains the same top speed potential. Large-diameter, wet multi-plate clutch is derived from a Suzuki GSX-R750 design to easily transmit power while the rack-and-pinion clutch release provides the rider with superb friction-point feel. The refined shift linkage helps the rider easily and quickly select the best gear for the riding conditions. The strong drive chain uses O-rings to preserve internal lubrication so power is transmitted smoothly and quietly.
CHASSIS FEATURES With styling influenced by the Suzuki GSX-S1000, but with its own aggressive turn, the Suzuki GSX-S750 bodywork looks wild and forceful yet keeps the rider comfortable at all times. The new headlight nacelle provides a visual focal point, while the under-cowl connects the chassis styling to the engine and new exhaust system. Frame design combines the advantages of a compact tubular-style street bike frame and a twin-spar sportbike frame to deliver a dynamic ride. A reasonable sport riding position is created by a carefully crafted relationship between the handlebars, footrests, and seat. Large-diameter, matte-black, tapered handlebars damp vibration while adding style and good control leverage for the rider. The low seat height of 820mm (32.2 inches) contributes to the sporty yet upright riding position and aids rider confidence at stops. Four-piston Nissin Monobloc brake calipers squeeze twin, 310mm, wave-style brake rotors up front with a single-piston rear caliper out back to help deliver controlled stops. Inverted, black anodized KYB fork features a spring preload-adjustable design, which provides a solid foundation for the Nissin radial-mount brake calipers. Trapezoidal, beam-type swingarm tapers down to precise chain adjusters that add strength and style. Link-type rear suspension, with a single shock absorber working through a progressive linkage, has seven-way adjustable spring preload. Developed directly for the Suzuki GSX-S750 models, the 10-spoke cast aluminum wheels from TPR hold Bridgestone Battleax Hypersport S21 radial tires that deliver increased grip and stability. The black-finish, aluminum hand and foot controls provide excellent action and contribute to the motorcycle’s sporty style.
ELECTRICAL FEATURES This Suzuki GSX-S750 has the Suzuki’s Easy Start System that requires just a simple touch of the starter button to fire up the engine (without pulling the clutch lever if the transmission is in neutral). Distinctively shaped headlight nacelle contains a bright 60/55-watt H4 halogen bulb. The tail section houses an integrated LED tail light with a dual-pane, red/clear lens. Similar to the Suzuki GSX-S1000, the new lightweight and compact instrument panel uses an LCD display that includes speedometer, tachometer, odometer, dual trip meters, gear position, coolant temperatures, driving range, average fuel consumption, instantaneous fuel consumption, traction control, and a clock function. The display has an adjustable-intensity, white-color backlight for great nighttime visibility and is flanked by LED indicators for the turn signals, high beam, malfunction, and traction control, plus coolant temperature and oil pressure alerts. A three-phase charging system, with an oil-cooled stator, keeps the maintenance-free battery up to charge for trouble-free operation.
