I don't mean to come across as offensive but I'm in a similar position as you, looking to get my first bike. I haven't rode an r6 but I've sat on one, and I'm personally not too fond of the riding position. It's real aggressive, the pegs are high which forces you to lean forward more, and I just prefer a more upright riding position. I've got a friend with an r6 and it's his third bike, he said he can see how it would be intimidating for a novice rider. Just about every rider I've spoken with has recommended that I start with a smaller size bike to start with. A bump in the road that may cause a novice rider's hand to slightly turn the throttle could buck you off an r6 if you're not careful lol. Whereas a smaller bike instills more confidence since it can be driven for all it's worth. Not only are smaller bikes easier to rider, they're also lighter, more maneuverable (flickable), and more forgiving to novice mistakes.
This is just what I've picked up prying my way into the wonderful world of motorcycles. Honestly everyone is different but I just thought I'd share some of the reasons I would choose a smaller bike. No matter the route you choose I'm sure you'll love the bike. Ride safe, and have fun.
