I've driven an older Suzuki GS500 and newish BMW F800, both parallel twins.
The Zuki is rather rough, especially at lower rpm.
The F800 is smoother, because of the fake 3rd pistonrod acting as a balancer, but still not as smooth as a 4-inline.

(Didn't ride these : )
Another reasonably smooth parallel twin is the Kawasaki 650 (W650, ER-6 range).
With more vibes - could have been designed in or simply not ironed out - there's the Triumph 865cc (Bonneville Thruxton America Speedmaster).

So in m/c applications, the inline twin is a well-proven concept.
