I own the VRSCR version but I've ridden the cruiser style VRSCB. (My preference is for the more upright seating, feet underneath me.) You won't have any problems with the ergonomics, I am the same height and inseam.
The engines are bullet proof. My dealer has sold a lot of VRSC models and they have never had to carry out a major repair on anyone of them.
