Is it just the noise that makes it seem more comfortable at high rpms, or the vibes, or the power delivery...? Power delivery is where these two designs usually differ the most, but it all comes down to the intended use the manufacturer made the motor for.
There can be a lot of differences between the character of a parallel and v-twin, based on many things like crankshaft weight and firing interval of the pistons. A parallel twin has half the camshafts/camchains of a v-twin, and the noise all those parts make is confined to a smaller area in a parallel motor. The vibes created the pistons and how well they are balanced can feel very different between the two architectures, a V-twin's angle between the cylinders affects this greatly. Thats not at all a comprehensive list but the physical differences certainly affect how it feels
There are v-twins that rev high with no complaints, the Suzuki V-Strom 650 is pretty similar to the Versys 650 in this respect, it redlines at the same RPM and due to gearing turns very similar RPMs out on the road. Felt happy for the short time I rode one.
Not knowing much about that Vulcan, I imagine its an engine made for a cruiser vs an engine coming from a sport bike and their intended design characteristics that feels so different. I agree the Versys motor likes to rev and will reward you for doing so!
