No experience with an in-line four (well, not on a motorcycle)
I had two BMW oilheads - an R1200GS and an R1100RT. The GS was a buzzer as I got it but with proper first service (on the road!) and throttle-body setting, the buzzing was toned down. Sold it as it was a tall bike and I was getting fatter. Not a good match.
The R1100RT was a buzzer, too. High-mileage used; bought for a ridiculously-low price. Sold it for the same price when a non-related issue caused a panic. False alarm but a wake-up to reality.
My Burgman 650 with a water-cooled 360-firing twin (and balance shafts) is a little bit smoother.
My old Honda GL500, with the water-cooled V, was a LOT smoother. There were vibrations from the V layout; but not, IIRC, the buzzing.
My TU250 buzzed a bit, but it was a high-revving small thumper.
So, the answer is...yes and no.
