Engine • 999cc 4-cylinder powerplant has a bore x stroke of 74.5mm x 57.3mm to bring enhanced throttle response across the entire rpm range and provide superior potential for racetrack performance. • Optimized camshaft profiles further enhance racing potential and were developed using proven MotoGP racing engine technology. • Optimally shaped hemispherical combustion chambers and a compression ratio of 12.9:1 promote low-range and mid-range performance and help achieve a broad torque curve. • Precision-manufactured 12-hole fuel injectors produce a fine fuel mist for more complete combustion. • Suzuki Composite Electrochemical Material (SCEM)-plated cylinders integrated into the upper crankcase reduce friction and improve heat transfer, durability and ring seal. • The unique Suzuki Drive Mode Selector (S-DMS) system allows the rider to choose different fuel-injection and ignition-system maps, adjusting power delivery to suit personal preferences using a button on the left handlebar switch assembly. • Pentagonal shaped ventilation holes in the sides of each cylinder bore reduce pumping losses normally caused by internal crankcase air-pressure resistance to downward piston movement. • The 4-2-1 exhaust system carries a Suzuki Exhaust Tuning (SET) valve maximizing torque and throttle response, especially in the low-to-mid rpm range.
