New Engine with MotoGP Design
The new engine revs higher and makes more peak horsepower, while maintaining excellent low-to-mid-range power and drive. It is a compact and lightweight inline four, DOHC with chain cam drive and four titanium valves per cylinder set at narrow angles, with a more over-square bore/stroke ratio, a higher redline and a higher compression ratio. The new engine has a bore and stroke of 76 mm x 55.1 mm with 999.8cc displacement. It uses a new valve train developed in MotoGP competition on the GSX-RR, using thinner-wall, hollow camshafts operating lighter, F1-style pivoting finger followers. The Suzuki Racing VVT (SR-VVT), Suzuki Exhaust Tuning-Alpha (SET-A), and Suzuki Top Feed Injector (S-TFI) systems combine to make the Broad Power System, increasing high-rpm performance without reducing low and mid-range performance. The result is strong, linear power and enhanced acceleration throughout the rpm range.
Suzuki Racing Variable Valve Timing (SR-VVT)
The Suzuki Racing VVT (SR-VVT), developed in MotoGP competition on the GSX-RR is unlike complicated systems used by other manufacturers, the SR-VVT system is simpler, more compact, and lighter. The system is built into the intake cam sprocket and an adjacent guide plate, using 12 steel balls positioned between slanted radial grooves in the intake cam sprocket and straight radial grooves in the guide plate attached directly to the camshaft. As centrifugal force moves the balls outward at high rpm, the offset grooves align, rotating the position of the cam sprocket on the camshaft and retarding intake cam timing, adding significantly to high-rpm power. The beauty of the SR-VVT system is in its compact simplicity, light weight, reliability and seamless operation. Centrifugal force is constantly produced when the engine is running, and is free in that it does not use power that could otherwise turn the rear wheel. For more than a decade, racers have not been able to feel when the system moved to change the valve timing. What they have been able to feel is a seamless, significant increase in high-rpm power, without sacrificing any low or mid-range. And the system is built into existing parts, takes up no extra room in the engine, with a minimal weight increase.
Suzuki Racing Finger Follower Valve Train
A new valve train developed in MotoGP competition. Each finger follower is 6 grams lighter than a conventional bucket tappet (10 grams vs. 16 grams), and because each follower pivots on a fixed shaft, its moving mass is just 3 grams. The lighter moving mass allows maximum engine rpm and valve lift to be increased while improving valve response and maintaining accurate valve control. Each finger follower in the GSX-R1000 is designed based on the actual followers used in the GSX-RR MotoGP race bike, including a DLC (Diamond-like Carbon) coating to increase durability.
