Bore and stroke of 74.5 x 57.3mm are different from the K8 model’s 73.4 x 59.0mm but still yield 999cc. A reshaped combustion chamber and cylinder head, thanks in part to a shorter intake camshaft with a relocated cam angle sensor, now sees a compression ratio of 12.8:1 vs. 12.5:1, and a lighter and reshaped airbox works with downdraft intake manifolds decreased in length by 10mm.
Titanium intake and exhaust valves are marginally larger, by 1mm each: 30 to 31mm and 24 to 25, respectively.
