Suzuki claims a new 999.8cc engine with a bore and stroke of 76mm x 55.1mm makes 199.27 horsepower at 13,000 rpm and 86.74 lbs.-ft. of torque at 10,800 rpm in European trim, using a new variable valve timing system developed in MotoGP to increase top-end power without sacrificing mid-range and low-end performance. The 31.5mm intake and 24.0mm titanium valves are opened with F1-style finger followers instead of bucket tappets and the compression ratio is 13.2:1.
The engine redlines at 14,500 rpm, features a screamer crankshaft with an even (180-degree) firing order and makes the new model the most powerful, hardest-accelerating GSX-R ever built, according to the company.
