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.
THe T-max for example has a "fake" 3rd piston with the mass of the other
two combined, going the opposite way, the "active" pistons are probably 360 deg too..
That engine has _no_ vibrations.
It's electric smooth.
Not to steal the thread but.. is the F800 a pain at all revs or is there a "band"?
My 650R was fine up to 6000 or so.
