which my 2007 didn't have.

The 270 crank on the 700X is spot on.

F800 has some other deal, right?
If I remember correctly both pistons go up and down at the same time?
Quite so; a 360* arrangement, but with a (pretty neat idea I must admit, but for my particular bike it obviously didn't work...) third connecting rod on the horizontal plane, and a pivoting set up to theoretically equal the mass/throw of the two vertical pistons.

Up until the F800, I'd had many Honda and Yamaha 180* twins, but they were all awesome, plenty of dual counter balancers and so on.

None of my single cyl bikes ever vibrated like the 800 did, either.
