Ok, you really needed to define medium beginner. I suspect you are thinking that because of dirt experience, which will do almost nothing for you.
Any bike Honda makes with RR in the name is not for anyone but the most experienced riders. The RR series are ready to race, except for having lights.
I know that you do not want people to criticize you for your choice in a bike, but when people are, they are trying to keep you from injuring yourself.
Here is some advice for the beginner:
1. Don't get a bike that is too fast for your first road bike. This is really way too easy to do, and because there are no graduated licenses in the US, it makes the consumer (you) have to do the thinking.
2. Everyone is out to get you! People will dart in front of you thinking they have the right of way, that you can get out of their way, and that you are an annoyance on the road.
3. Everyone is stupid! If you see that there is an opportunity for someone to do something stupid, they will! This is also true of a motorcycle rider on a bike too big for their skills as well, so look within first.
4. Everyone is drunk! You will see a lot of swerving, and lane changing that people do is unneciscary, and you need to watch closely.
5. You are invisible! This is mostly true anyway, and you must assume no one sees you. Also, stay out of blind spots on cars, even if they see you, the moment you go into a blind spot, they immediately forget you were ever there.
6. The rules of the road become null and void in a parking lot! Difference here as opposed to a car, is that the little bump that would make people exchange information here, can, and often does, kill a motorcycle rider.
Really, you need 1 crash free season on a 250, on the road, and I mean not dropping or crashing it, before ever attempting the 600RR, if you do not have at least that, you are not ready foor the RR, Just a flat fact!
