// Four-stroke, liquid-cooled, DOHC, 999.8cc inline-four cylinder engine is designed with a high level of top end performance plus strong low to mid-range power.
// The crankshaft retains Suzuki’s Even Firing Order Engine legacy. Un-even firing order engines used in other motorcycles vibrate more while the GSX-R1000 makes good power at all engine speeds, runs smoother and reliably while emitting a screamer exhaust note.
// The short stroke engine has a 76.0 mm bore versus a 55.1mm stroke, yet is narrower than the prior generation GSX-R1000 thanks to effective design.
// The fresh-design engine has been rotated back and positioned in the frame to create optimal chassis dimensions for precise handling and to balance the motorcycle’s weight.
// The new and exclusive Suzuki Racing Variable Valve Timing System (SR-VVT) uses a centrifugal actuated mechanism on the intake camshaft sprocket to increase high engine RPM power without losing low-to mid-range power.
// The new design Suzuki Racing Finger Follower valve train weights less than a tappet-style valve train for reduced friction and increased valve response at higher engine speeds.
// Titanium valves, two 31.5mm intake and two 24mm exhaust valves, are used for each cylinder. The lighter valves respond well to the finger follower’s arms and permit a 14,500 RPM redline that helps produce very high peak horsepower.
// Aluminum pistons, 76.0 mm in diameter, were engineered with use of FEM (Finite Element Method) analysis, and are cast for optimal rigidity and weight.
// Suzuki Composite Electrochemical Material (SCEM) coated cylinders are integrated into the upper crankcase to reduce friction and improve heat transfer and durability.
// The high 13.2:1 compression ratio helps produce high horsepower. The cylinder head’s shallow combustion chamber minimize heat produced during operation.
// The EFI system uses Suzuki’s new Ride-by-Wire Electronic Throttle Bodies where the throttle valves are controlled by a servo motor for fast response to rider throttle grip input while delivering precise and smooth power delivery.
// The automatic Idle Speed Control (ISC) improves cold starting and stabilizes the engine idle regardless of engine temperature.
// Complementing the four primary fuel injectors in the throttle bodies are four Suzuki Top Feed Injectors (S-TFI) that spray fuel from the top of the air box directly into the intake funnels. This results in higher peak power, more efficient combustion, and a higher level of fueling control.
// To increase top end power without losing lower RPM performance, the air box is equipped with Staked Air Intake Funnels for the #1 and #4 cylinders. This simple design allows good air flow at all intake speeds without requiring a mechanism that adds weight or complexity.
// New design Suzuki Ram Air Direct (SRAD) intake ducts are used to exponentially increase the volumetric flow of air amount coming in the air box as road speed increases.
// The 4-2-1 exhaust system with titanium muffler is designed helps the engine deliver a wide range of performance with an exciting rush up to redline. The titanium muffler has a pleasing appearance while creating an exciting, distinctive sound.
// The Suzuki Exhaust Tuning (SET) system valve in the mid-pipe helps control back-pressure and flow to the muffler to widen power delivery and reduce exhaust sounds without needing a larger silencer.
// New design SET-Alpha exhaust valves are in the balance tubes between the #1 and #4, and the #2 and #3 head pipes. Actuated by a cable from the main SET-valve, the Alpha valves open at higher engine speeds and close at lower RPM to help the engine create high peak power without losing low and mid-range horsepower.
// The cooling system was designed using advanced analysis design so the coolant flows through the engine and radiator more efficiently. This design uses 400cc less coolant than the prior GSX-R1000, but the new system has better cooling efficiency while being more compact and lighter.
// The fairing lowers efficiently guide cooling air to the high-capacity curved radiator. Twin cooling fans ensure good cooling at lower road speeds.
// Additional heat is removed from the engine via the use of an air-cooled, radiator-style oil cooler mounted directly below the main radiator.
