Never ridden a versys so cant compare but would imagine it might feel slightly more sane than a Duke.But if you've got an Explorer for the sensible you might enjoy the contrast of something not so!
Personally I love the fact that its clever i.e.. very fast for a single ,very economical , comftable , and oh so light.Its a "pure" motorbike just your basic wheels frame and engine.It would make a great basis for building a special in my opinion
