When I were a lad 
… you got a 50 at 16, rode that for a year, then a 125 at 17 for another year or so … did your test and got a 250/400, then a 600 … then a tou …
Its all good - learning something from each stage and looking forward to the next rung on the ladder …
This appears all but gone these days
… people are not starting at 16 these days … just doing their tests and getting straight on a half decent to red hot bike!!
Where is the fun in that?!
Also I firmly bleiave that riders will be better if they have come up the rungs instead of just hopping straight on a fast/big bike …
BTW I think an SV650 is OTT for a first bike … get back out on ya 50s and 125s old skool!!
