The only thing I remember reading in the press releases about the engine was that it was "all new" and 1kg lighter than the old 300 motor. I'm sure there is lots of cross over parts inside there from both the 300 and 650 motors.
I read somewhere recently that 30% of the engine components in the 300 motor dated way back to the original GPX250 motor from the late eighties.
