Get the checkbook ready - you'll eventually want a different seat, a backrest, and highway pegs at a minimum. Then come upgraded speakers, new grips, etc.
I've already purchased a passenger backrest and I just ordered the 8" recurve from Clearview. If I can find the money, I'll probably get lower fairing before the winter is out, as I want to commute all winter. And you are right, my list of nice to haves is already a mile long.
