2011 Suzuki GSX-R1000 Features
Suzuki GSX-R1000 with a firm defines its dominance, having won the championship seven times in the AMA Superbike Championships in a row.
The engine is built with high-quality titanium valves, forged pistons and shot-peened conrods.
The combustion chamber accommodates large intake and exhaust valves. Intake valve size is 31mm and exhaust valve size is 25mm.
The engine's oversquare bore and stroke of 74.5mm x 57.3mm gives it specifically increased performance at high RPM.
The compact engine allowed Suzuki engineers to incorporate a shorter wheelbase design with a longer swingarm for improved racetrack performance.
The SDTV (Suzuki Dual Throttle Valve) system uses two butterfly valves in each throttle body barrel, the primary valve controlled by the rider via the twist grip and the secondary valve controlled by the ECM.
This ultimately reduces fuel consumption and exhaust emissions. A large, efficient radiator with a trapezoidal shape developed on factory team racebikes and a trapezoidal engine oil cooler both help reduce drag. Suzuki Advanced Exhaust System (SAES) uses an under-engine chamber with low-slung, large-volume race-inspired titanium mufflers.
Transmission Features
The back torque-limiting clutch incorporates the Suzuki Clutch Assist System (SCAS) for light clutch pull and optimum clutch performance. Lightweight Showa Big Piston front Forks (BPF) 43mm fork design eliminates the internal cartridge assembly inserted into each fork leg and instead uses a single 39.6mm upper piston riding against the inside wall of the inner fork tube. The rear shock offers adjustable rebound damping, spring preload, and both high-speed and low-speed compression damping.
The front brakes feature fully floating 310mm discs and rigid, lightweight race-proven monoblock forged radial-mount calipers.
The edgy and clean GSX-R1000 styling incorporates fairing and bodywork details aimed at reducing turbulence and drag.
LCD readouts include odometer, dual trip meters, reserve trip meter, clock, coolant temperature/oil pressure warning indicator, gear position indicator, lap timer/stopwatch, S-DMS setting indicator and bar-graph indicating the instrument lighting level, or brightness.
The only major change compared to the 2010 models are the colours schemes.
Suzuki calls the GSX-R1000 "An unsurpassed package" thanks in large part to its high performance 999cc, four-cylinder liquid-cooled DOHC engine.
It also features Suzuki's Drive Mode Selector (S-DMS) which can tweak the power output, plus there's a back-torque-limiting clutch and titanium mufflers.
