good call. Yes, the *full* factory specifications did not include weight ( either wet or dry), and hp..........so it really should have been called the 98% factory specification sheet 
230kg dry weight was quoted from 'the man'.......he also said it may change due to final specs for weight and hp not being finalised by the Big K at this stage (enter MV F4 as you have pointed out....).
If they wait too long, then in the meantime someone else will build a bigger faster rig
, and at this stage, release date has already been put back to the *middle* of next year because Kawasaki want to make sure it is the most powerful.......and they have developed a number of different HP motors, so will *probably* choose the maddest & baddest one they have made.....
Definitely not an *all-new* motor, basically a bored-out 12 with some flash *new* external covers, re-worked internals etc. When your on a good thing, stick to it
One thing is for sure - it is pretty *easy* to drag 225 RWHP out of a 12 motor, Yoshi cams / flowed head are a good start !
, all this, less than 3 months after buying my 12
