From Motorcyclist Magazine, January 2009

The engine is a clean-sheet design, engineered to be smaller and lighter while producing more power and fewer emissions. A more oversquare bore of 74.7 x 57.3mm (versus the old 73.4 x 59.0mm) boosts top-end performance, while reshaped combustion chambers (upping compression from 12.5:1 to 12.8:1) make room for larger valves (31mm intake, 25mm exhaust), actuated by revised cams for increased low- to mid-range power.

The transmission's input and output shafts have been shuffled, reducing engine length and allwing the crankcase to be simplified (now two pieses as opposed to three) and lightened.
Shouldn't be long after these hit the streets that someone will lay one down and part it out. Let the race to find one begin.
