Well, id say all rounder, mainly commuting. It will be used to go around 20 miles 5 days a week, and then social riding of an evening / weekend.
You dont want to have to commute on an RS125 m8 - total nightmare, especially if a lot of it is town work.
I will confess, I am a big Aprilia "fanboi". I run an RSV Mille.

But if I was a learner and looking to get into biking, an RS125 would not be near the top of my list.
Grab something cheap to learn on, do your CBT, pass your test in however manner who intend to do so ( Direct Access or otherwise ) and move onto something bigger, albeit restricted, to cut your biking teeth on.
