The 180 crank on my 650R was a horror, needed rubber mounting etc
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.
