SUZUKI took the wraps off three new models at the Intermot Motorcycle Show in Cologne, Germany, with the iconic GSX-R range getting all-new 600 and 750 models, along with the debut of a new naked middleweight – the GSR750.
The new GSX-R600 boasts heightened performance levels thanks to MotoGP inspired development that has seen the new bike shed an impressive nine kilograms over its predecessor, thanks partly to an all-new chassis that has a 15mm shorter wheelbase, as well as Showa Big Piston Forks.
With engine technology advances, the new GSX-R600 also offers heightened performance, due to a host of innovative features taken straight from MotoGP, including lighter, more durable pistons designed with the same Finite Element Method (FEM) and fatigue analysis technology used to develop MotoGP engines. Combined with thoroughly reworked cam profiles and narrow valve angles, the new GSX-R600 delivers this enhanced performance through a vertically staggered, close ratio gearbox with shorter ratios for good race start performance and better corner exit drive.
Developed in parallel with its smaller sibling, the GSX-R750 remains at the top of its game too with similar treatment to make it the best 750cc sports bike yet. Combing similar weight advantages over its predecessor, with the same shorter wheelbase and pin-point accurate chassis of the 600, the new GSX-R750 makes the perfect sporting road tool thanks to its over-square engine that produces a race proven bore/stroke ratio, in turn contributing to better efficiency, higher RPM and performance.
Making both models stop as well as they go is the introduction of radial-mount Brembo Monoblock calipers with fully-floating front discs. Featuring 310mm discs and 32mm staggered caliper pistons, the GSX-R600 and 750 offer significantly enhanced braking performance, with the added bonus of decreased weight too, all adding to machines that offer class leading power to weight ratios in their class*
Also unveiled at Intermot was Suzuki’s all-new GSR750 – a blend of the modern and the futuristic with a powerful 749cm3 four-cylinder fuel-injected engine.
With strong lines running from nose to tail, the GSR750 combines edgy styling with a strong specification that will boost rider confidence and flatter ability. Thanks to a unique chassis that incorporates the best qualities of a compact tubular street bike frame and the pin-point accuracy of a twin-spar sportsbike frame, the new GSR750 tracks with real confidence thanks to 41mm KYB inverted front forks and an adjustable rear KYB shock absorber.
Starting with the proven power-plant of the GSX-R750, engineers began with real pedigree, creating an engine more akin to a naked motorcycle – responsive with distinctive character, offering hard acceleration.
Modifications to the GSX-R750 engine include revised cam profiles, intake and exhaust tracts and a 12.3:1 compression ratio that provides strong, linear torque starting at low RPM. With the valves set at a very narrow angle, the combustion efficiency is improved, therefore delivering better low-rpm, mid-range response, acceleration and fuel mileage as well as reduced emissions.
With styling a large consideration in the bike’s development, the GSR750’s nimble chassis and punchy power is topped off nicely with modern, vented headlight shell, integrated instrument cluster, moulded rear-view mirrors, light and open radiator side panels and aggressive front bodywork. With particular consideration paid to rider comfort too, thanks to a well-shaped seat and textured fuel tank side panels, the GSR750 offers real world sporting ability.
All three models make their UK debut at Motocycle Live at the NEC in Birmingham from November 27 – December 5.
