Hey Fabio welcome, I'm new too, I thought I should offer you my experiences on the two of these I've used. Unfortunately I didn't use the Yamaha, :/ which I know is your favourite, perhaps tell us why?
Any of your three, I don't think you can go wrong.
I have riden extensively on a CBR 125R (more than the RS4!), about 3 hours of riding on a 'pre-learner' course I did, another 3 or 4 for the tests I did to get my learners permit.
This was my first experience with a motorcycle, it felt like magic having my feet on both pegs for the first time, leaning over, I would say that it's a great bike. All of these were good; controls, clutch, instruments, riding position, brakes, and of course, the price.
The not so good; extremely sensitive throttle, looks, kick stand, sound - no deal breakers to me.
Now the Aprilia RS4. I'm completely biased, because I've bought one - and I love it! The Aprilia spoke to me, I got on a brand new one, rode it for 2kms, and I was hooked, sold, over-joyed, it's been 5 days, I still can't wipe the grin from my face. You see on paper, its only a little bit faster than a CBR 125R, but to me it's special.
The good; It's georgeous, full fairing, excellent sound, very revvy, I got it up to about 65km/h my test, I used the quick shifter (which mine has) that's an amazing feature. Great chassis, controls, brakes, the build quality too.
I've already dropped my bike :O completely freaked out, I was rolling slowly, looked behind, then looked back and a car was heading right for me! I was turning left, so I tried to brake (front brake) and it just collapsed on me, BUT! No marks on the fairing! I let it land on my left boot, and just a minor scuff on my left handle bar, otherwise still perfect!
The not so good; the seat is a little bit higher (+27mm, but I couldn't tell), it needs to be revved more, torque and power are higher up, so might make for a worse commuter stopping and starting, clutch is a little harder to use than the CBR too, it's a less popular bike so less people to talk to about it, oh and of course, the price.
You're welcome to have a look at my RS4's pictures here
If you're buying the bike yourself, like the other guy said, maybe get a used one that's in good / ok condition, then save up for a better bigger one.
Another thing that helped me decide was a british review of all three of your bikes and one other, check that out here (the Italian subtitles may work too by the way)
These are my thoughts, hope it helps and good luck on your test and chosing!
