New engine features include revised camshaft profiles, shot-peened conrods, chrome-nitride-coated upper compression and oil control rings, and pentagonal ventilation holes. The 4-into-1 stainless-steel exhaust system with a titanium muffler uses a Suzuki Exhaust Tuning (SET) valve to improve torque and throttle response in the low-to-mid RPM range. The Suzuki Drive Mode Selector (S-DMS) offers push-button selection of two racing-developed engine control maps to suit road conditions and personal tastes. Suzuki Dual Throttle Valve (SDTV) fuel injection uses fine-spray 8-hole injectors for improved fuel atomization, which contributes to more complete combustion. Also found on the 2011 Suzuki GSX-R 750 is a race-developed, lightweight Showa Big Piston front-Fork (BPF) and Single Showa rear shock that features externally adjustable rebound and compression damping, along with adjustable ride height. Even more trick on the Suzuki may be the Brembo front brakes with fully floating 310mm discs and radial-mounted, four-piston monoblock calipers. The 750 GSXR instrument cluster features an analog tachometer with LCD readouts of the speedometer, odometer, dual trip meter, reserve trip meter, clock, coolant temperature/oil pressure indicator, S-DMS and gear position indicators.
