The New 2011 Suzuki GSX-R600 – The European motorcycle press had their first contact with the new Suzuki GSX-R600 this week in the racing circuit of Almeria in Spain – and the initial responses are that the motorcycle sport has taken a leap forward in many areas. The motorcycle model GSX-R600 features two brand new chassis designs, each based on a more compact, lightweight twin-spar aluminum chassis with a wheelbase 15 mm shorter. The GSXR 600 now has a wheelbase that measures 1385 mm. The 2011 Gixxer 600 shares of the motorcycle engine design compact and powerful four-cylinder GSX-R 750. The liquid-cooled engine with Suzuki Ram Air Direct (SRAD) induction and a digital engine management. Double overhead camshaft (DOHC) are driven by a chain link plate of a forged crankshaft and open four titanium valves per cylinder via bucket tappets, with shim-under-bucket adjustment tabs.
The valves are set at a narrow angle, 22.0 degrees for the GSX-R600-allowing a very compact Twin Swirl Combustion Chamber (TSCC)-with the GSX-R600‘s intake valves set at 10.0 degrees from the cylinder centerline. The exhaust valves are set 12.0 degrees from the cylinder centerline. The four-into-one stainless-steel exhaust system features four individual head pipes and a single collector. The GSX-R 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. The Suzuki GSX-600 exhaust chamber leads to stainless-steel S-bend pipe and a titanium motorcycle 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-R600 system 1700 grams (3.75 lbs.) lighter. The new 2011 Suzuki GSX-R600 also uses lighter, more durable forged pistons designed with the same Finite Element Method (FEM) and fatigue analysis technology used to develop MotoGP racing engines.
