I went from MC's to scooters and Maxis a few years ago and cant ever see going back. I'm not a top-speed guy but enjoy the twisites and my Burgman 400 satisfies. Not brilliant in anything, but all things combined, make it much more desirable to me than a motorcycle. I can scrape the centerstand but only when really cranked over. If you can remember its not an R1, which shouldnt be too hard, you'll be OK. You will still be able to keep up with a nu-Gen sportbike kiddie though.
Riding an automatic bike takes some getting used to but I cant see ever going back to a shift bike as a daily rider after time on the maxi.
