Interesting. I've been looking at the F800GT's but everything I've ever read screams about the handlebar vibrations from that engine. I would say it's the number one complaint, bar none. (is that a pun?) The tester of the F800 in this Visor Down video would disagree (1 min in and again at 2:08) with you: https://www.bing.com/videos/search?...FDB65E2223ADFF6A24A8FDB65E2223ADFF6&FORM=VIRE

We have two F800s. Total of 240,000 kms. Vibration isn't objectionable and in fact I can't remember even thinking about it.
Yeah but i believe Ducati was still the first to use the double connecting rod counterbalance system on the Supermono, although they only made a very few of those engines. I think it works better on a 90 degree angle (for reasons too detailed to discuss here), but the Rotax 804 can run pretty smooth, especially if the fueling is right. I readily admit i do not understand why fueling is a factor, but at least it was on my bike.

I have never ridden an 800ST but did experience some high frequency, low amplitude “buzz” on the handlebars of a 700GS, but was able to eliminate most of it with some modification.

The F800/700 bikes are 360 degree cranks. One piston on compression and one on exhaust both going up and down together. The F750/850 motors have a 270 degree offset crank. They typically run smoother and make more power because there is always one piston moving unlike 360 and 180 degree offset twins.
