Congrats man, perfect timing!
Take some time to learn and adjust to your new ride, coming off a Sportbike myself, I can attest to having to re-learn a lot of things about riding. Enjoy her, she will ruin liter bike acceleration forever lol.
First one that got me was getting pants stuck on foot pegs constantly. Second one was on the SB I could hang off just a little and it made a big difference in corners, on the R3, since it is so much heavier than the rider you really have to move around if you are going to hustle it, same holds true for very low speed maneuvers, if you want to do full lock turns with stability you really have to counter weight the bike with your body a lot more.
