In 1985, Suzuki revolutionized the sportbike category with the introduction of the original Suzuki GSX-R750. The 2021 Suzuki GSX-R750 continues Suzuki’s tradition of building Supersport bikes powered by strong engines carried in lightweight and nimble chassis.
On the road or on the track, the Suzuki GSX-R750 delivers a breathtaking combination of outstanding engine performance, crisp handling, compact size, and light weight. Its secret is an unequaled pairing of 750cc performance with the compact chassis of a 600cc Supersport, complemented by technologically advanced suspension front and rear.
The 2021 Suzuki GSX-R750 remains true to the GSX-R’s original concept and Suzuki’s championship-winning heritage, delivering an exciting riding experience you can use on the street or on the racetrack – it’s your choice.
2021 Suzuki GSX-R750 Features
KEY FEATURES The GSX-R750’s look was born and raised on the racetrack, and for 2020 that styling has a pair of dual-color paint schemes. Riders can choose a glossy Glass Sparkle Black/Pearl Glacier White scheme or Metallic Matte Black/Glass Sparkle Black look that blends a shiny and flat finish. Each scheme includes complementary graphics and wheel rim accents.
The GSX-R750’s fuel-injected, 750cc, four-cylinder engine powers a balanced sportbike experience. This engine pulls strong off the bottom like a larger-displacement powerplant while it builds revs like a smaller mill – it’s the best of both worlds.
The Suzuki Drive Mode Selector (S-DMS) lets the rider adjust the engine’s power delivery to suit the riding conditions.
The twin-spar aluminum frame effectively connects the steering head with the swingarm pivot portion of the chassis in a way that balances light weight and strength. The engine is suspended below the frame to keep mass low and the wheelbase short to promote nimble handling.
The Showa Big Piston Front Fork (BPF) and remote reservoir rear shock absorber are fully adjustable to deliver exceptional handling.
Twin Brembo Monobloc, radially mounted front brake calipers grasp fully floating stainless steel brake rotors to deliver strong stopping power.
ENGINE FEATURES Compact, 750cc, four-cylinder engine with a race-proven over-square bore/stroke ratio produces remarkably strong high rpm power delivery.
The energy-efficient engine employs forged pistons, shot-peened connecting rods, chrome-nitride-coated upper compression and oil control rings, and pentagonal ventilation holes to reduce frictional and mechanical losses.
Lightweight titanium alloy valves are controlled by single-coil valve springs to reduce valve-train mass, reducing mechanical losses at high rpm.
Suzuki Dual Throttle Valve (SDTV) fuel injection uses eight fine-spray eight-hole injectors for improved fuel atomization, which contributes to more complete combustion.
An Engine Control Module (ECM) provides state-of-the-art engine management and has enhanced settings to suit the intake and exhaust systems, resulting in better fuel economy and linear throttle response.
Advanced MotoGP-developed transistorized ignition control programming helps maintain more precise spark timing across the range of engine speed and temperature.
Suzuki Drive Mode Selector (S-DMS) offers push-button selection of two racing-developed engine control maps to suit road or track conditions and personal tastes.
Four-into-one stainless steel exhaust system with a titanium muffler is fitted with a Suzuki Exhaust Tuning (SET) valve that maximizes torque and improves throttle response, especially in the low- to mid-rpm range.
The close-ratio six-speed transmission features a taller first-gear ratio and shorter ratios for second, third, fourth, and sixth gear, making it easier for a racer to get a good start while improving straight-line acceleration and drive out of corners.
Race-proven back-torque-limiting clutch contributes to smoother downshifting and corner entry.
CHASSIS FEATURES Lightweight and compact twin-spar aluminum alloy frame is constructed of five cast sections to produce a balance of light weight and strength.
The frame is mated with a cast aluminum swingarm and multi-piece rear sub-frame that’s ready for racetrack use.
Race-developed, lightweight Showa Big Piston Front Fork (BPF) delivers superb feedback and consistent performance.
Single Showa rear shock features externally adjustable rebound and compression damping, along with adjustable ride height.
Electronically controlled steering damper provides lighter steering at slower speeds and more damping force at racetrack and highway speeds.
Front brakes with fully floating 310mm discs are grasped by radial-mount, four-piston Brembo Monobloc calipers.
Three-spoke cast aluminum alloy wheels are shod with lightweight, high-grip front and rear tires for sharp handling.
Three-way adjustable foot pegs, adjustable shift lever, and short fuel tank help compose a comfortable riding position that permits the rider movement required for performance riding.
Compact, lightweight instrument cluster with a built-in lap timer/stopwatch and programmable engine rpm indicators to alert the rider to certain shift points.
Trim, simple, and lightweight bodywork creates an exciting, aerodynamic style that truly works well at speed.
Distinctive multi-reflector headlight with vertically stacked high- and low-beam halogen bulbs is centered between position lights on each side.
Bright, durable LED tail light, with clear lens.
The front turn signal are integrated into the rearview mirrors while the rear tail section houses the rear signals.
The lightweight instruments also include an analog tachometer and LCD readouts that show speed, odometer, dual trip meter, reserve trip meter, clock, coolant temperature/oil pressure indicator, S-DMS, and gear position indicators.
Attention to rider comfort and confidence includes a carefully shaped seat with a high-grip cover.
The wheel rims have pin stripes punctuated by “R” logos that highlight the bike’s identity.
