2021 Suzuki GSX-R750 : OWN THE RACETRACK.
Introducing the 2021 Suzuki GSX-R750…
It wasn’t by accident that the original GSX-R750 redefined the high-performance Supersport and shocked the motorcycle world when it was introduced in 1985. It was a product of integrated design, a talented group of Suzuki chassis, engine and electrical engineers making history by working together to build a more compact and lighter 750cm³ Supersport
With an unmatched combination of excellent throttle response, linear power delivery, strong braking, confident handling and class-leading power-to-weight ratio, it was the closest a mass-production four-stroke, four-cylinder street bike had ever come to being a race bike with lights.
As Suzuki marks its 100th anniversary as a company in 2020, the new 2021 GSX-R750 100th Anniversary Edition arrives to celebrate the brand’s achievements on the racetrack.
In 1985, Suzuki revolutionized the sportbike category with the introduction of the original GSX-R750. The 2021 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 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 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 Totalmotorcycle.com Key Features
- Born and raised on the racetrack, the 2021 GSX-R750’s iconic styling features a Metallic Oort Gray or Pearl
- Brilliant White paint scheme that includes contrasting front fender and wheel graphics colors.
- 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.
EFFICIENCY BY DESIGN
Combustion efficiency is a measure of how completely an engine burns its fuel. Better combustion efficiency can increase power and torque output across the rpm range; improve throttle response, acceleration and fuel mileage; and reduce emissions. Mechanical efficiency is a measure of how much of the power and torque produced by an engine actually reaches the rear wheel.
Reducing mechanical losses by minimizing internal engine friction, reducing the weight of reciprocating internal parts and relieving crankcase pressure can increase mechanical efficiency, putting more of an engine’s output to use actually moving and accelerating the motorcycle and also improving fuel mileage and reducing emissions.
A LIGHTER, MORE COMPACT CHASSIS
The GSX-R750 features a complete chassis design based on a more compact, lighter twin-spar aluminum frame with a 15 mm shorter wheelbase totaling 1,390 mm.
The shorter wheelbase better centers the combined machine/rider mass between the wheels, improving racetrack cornering and also shortening the reach between the seat and the handlebars. The shorter reach and slightly wider handlebar angle make it easier for the rider to re-position their weight while on the racetrack and also improve comfort on longer highway rides.
ENGINE DESIGN
The four-into-one stainless-steel exhaust system features four individual head pipes and a single collector. The mid-pipe located between the collector and the under-engine exhaust chamber carries a Suzuki Exhaust Tuning (SET) servo-controlled butterfly valve to match exhaust system back-pressure to engine rpm, throttle position and gear position, maximizing torque and improving throttle response, especially in the low-to-mid rpm range. The exhaust chamber leads to stainless-steel S-bend pipe and a titanium muffler shaped and positioned to enhance cornering clearance and improve aerodynamics. A reduction in pipe wall thickness and a smaller, more efficient exhaust chamber and muffler combine to make the GSX-R750 system 1,100 grams lighter.
A slightly larger-diameter radiator fan mounted on the efficient, trapezoidal, curved radiator turns on and off based on coolant temperature and improves cooling performance.
2021 Suzuki GSX-R750 Totalmotorcycle.com Features and Benefits
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.
