The 84mm bore size previously mentioned doesn't make much sense to me. Unless there are two distinct variations of the V4 motor that will share some external parts...
84MM bore - Makes perfect sense for a 1200-1300 V4 sportbike or power cruiser and maybe even a true sports tourer too. But...IMO The engine cases would be then be too big and heavy for 1000CC class SBK, which is limited to a 81mm bore.
So I'm thinking that Ducati must be working on a couple similar but different V4 engines. One for competing in WSBK and another will be for high torque street platforms that will be premiering a few years down the road. Pretty smart move considering that Euro V is coming.
One of the articles mentioned that the base engine will be a 1200cc motor, and that the "R" version will be a 1000cc motor for WSBK requirements.
