Hi and welcome. I too came back after along break, 20 years, and I have a blue K2 1000. You'll soon find out that the blue ones are the quickest.
My wife loves the bike, although I am fairly large she is small and has lots of room. My son thought that the top box was not very cool until I took him out on the bike without the top box. He now thinks it's useful for keeping him sliding off when I accelerate.
Have lots of fun on your new ride.
