DOMINANT FORCE: DIRECT ACCESS RACING TECHNOLOGY
The new Suzuki 1991 Gsx R 750 M brings to 750cc class production motorcycles an all-around superiority WON in successful factory racing actions and proven in a wide range of production endurance racing events. Powerful, circuit-bred performance features like engine improvements straight out of the factory team's race shop, rigid inverted front fork and Suzuki's unique progressive link rear suspension all cradled within an aluminum-alloy frame and swingarm whose efficiency has been proved with modified racing engines. The new Gsx R 750 M is another Suzuki success in efficient application of racing technology — technology that’s made the Gsx R 750 M the dominant force in 750cc Stock Production-based racing — to street bikes. It's direct access racing technology in action.
Nothing speeds technological development and advances the state of the engineering art as rapidly as racing. The racetrack rewards all-around function. Success in racing comes to efficient high-performance machines, racing motorcycles that accelerate harder, corner faster, stop quicker, simply work better. Nobody builds better racebikes than Suzuki: The Grand Prix-winning RGV500 and the stunning 750cc Formula-1 Gsx R 750 M R fielded by the Suzuki factory team are proof of that fact. But building exotic racebikes is one thing. Applying racing technology to production street motorcycles without building in an outrageous pricetag is another. That's what makes the high-performance Suzuki Gsx R line different: The direct, efficient application of racing technology. Technology that makes the 1991 Gsx R 750 M simpler, lighter, more efficient, better than the competition. Technology that made the Gsx R 750 M the dominant force in 750cc Stock Production-based racing and the backbone of privateer racing the world over. The 1991 Gsx R 750 M is more than the best all-around high - performance 750cc street motorcycle available off a showroom floor today. The 1991 Gsx R 750 M is direct access racing technology.
A Revolutionary Engine, Refined
Revolutionary for its combination of high torque output, design simplicity and light weight. Suzuki's unique 1991 Gsx R 750 M engine has been continually refined since its introduction. This air-cooled with SACS (Suzuki Advanced Cooling System), race-proven 749cc power-house has a bore and stroke at 70 x 48,7 mm, four valves per cylinder, double overhead camshafts and Suzuki's TSCC (Twin Swirl Combustion Chamber) design. Racing-design connecting rods carry lightweight pistons with recessed wrist - pin bosses, cut-away skirts and light, thin rings that reduce friction and resist fluttering and loss of ring seal all the way up to the 13,000 rpm redline.
Suzuki Advanced Cooling System (SACS)
The Suzuki Advanced Cooling System (SACS) combines with air cooling to efficiently keep the 1991 Gsx R 750 M engine at optimum operating temperatures. SACS is a separate, high-volume oil flow system that carries engine heat to an efficient, high-capacity, curved Radial Flow cooler SACS results in engine temperatures much lower than those achieved with air-cooling alone, and SACS is simpler and lighter than competing water cooling systems
The Suzuki 1991 Gsx R 750 M breathes through Slingshot smoothbore carbs featuring a unique slide design developed by Suzuki engineers working with Mikuni technicians. The design combines the best performance features of a flat slide and a round slide, delivering the quick response and reduced throttle-movement resistance of a flat slide and the less-turbulent airflow and better sealing of a round slide. A smooth-radius air intake bell, without ridges, increases intake efficiency. A vent circuit built into each carburetor reduces negative pressure underneath the slide diaphragm, allowing the slide to rise more rapidly and improving throttle response. Slingshot design carburetors are lighter than conventional carburetors and are easier to work on, making jetting changes faster and simpler at the racetrack.
Cool Air Induction System
Cool air is dense air, and dense air means more torque output.
Four-Into-one Exhaust System
Suzuki's microcomputer-controlled digital ignition system provides ideal ignition timing at every engine rpm. Timing is not affected by heat or humidity.
Race-proven Clutch with Rack-and-pinion Actuation
The Gsx R 750 M's race-proven clutch has six beefy coil springs.
Compact, Strong Racing Frame and Swingarm
The 1991 Gsx R 750 M's aluminum-alloy frame and swingarm are an exceptionally light and rigid combination of state-of-the-art castings and extruded straight-wall tubing.
Inverted Front Forks
Any racer who has made back-to-back comparisons will tell you that the fastest way to improve handling is to replace conventional front forks with a set of inverted forks. Race-proven inverted forks simply work better, and that's why they're standard on the 1991 Gsx R 750 M. Unlike conventional forks, the 1991 Gsx R 750's inverted forks have the stanchion tubes on the bottom, carrying the axle. The stanchion tubes slide inside larger diameter upper tubes grabbed by forged aluminum alloy triple clamps; because there's more surface area gripped by the triple damps, the entire assembly is more rigid, reducing side loading of fork bushings and improving fork response.
Progressive Link Rear Suspension System
Suzuki's unique progressive link rear suspension system becomes progressively firmer throughout its 136mm (5.35 inches) of wheel travel, improving response
Wide Cast Wheels. Radial Tires
The 1991 Gsx R 750's wide, cast aluminum-alloy wheels carry 17-inch high-performance radial tires.
Four-piston Calipers, Floating Front Brake Discs
Race proven stainless stool alloy, 310mm (12.2-inch) front brake discs feature surface slotting and floating carrier mounts to help resist heat related distortion.
The 1991 Gsx R 750's fairing and bodywork design came stra^straight off the factory team's 1990 racebikes. The wind-tunnel refined fairing features a slanted nose, flush mounted headlight assembly and raked windscreen tor less lift, smaller frontal area and reduced drag. The sidecovers and tailsection smooth the airflow behind the rider's legs.
Wider Seat and Optional Solo Cover
A new, wider seat increases rider and passenger comfort. An optional cover is available to replace the rear seal section, for solo riding.
Dual Lighting, Complete Instrumentation
The 1991 Gsx R 750's new dual-halogen-bulb headlight assembly is complimented by a new front running light and a now dual-bulb taillight integrated into the tailsection.
