Used to love mine. My knees wouldn't be able to handle it these days. At 6'1" I was always a bit too tall for it and a few more years will have done nothing to help the situation. If I ever saw it for sale again, I'd maybe buy it back as objet d'art.
Borrowed my mate's XV535 for three months when my bike was being repaired. He put a fork brace on it which improved the "handling" somewhat. I gave it back to him with the footpegs ground to feck and offered to replace them but he didn't seem to mind. A lot of fun but it did give me backache 15 minutes into a ride.
Couple of Buell’s I’ve owned over the years. They are great fun but I never trusted the belt drive as they seem to snap on a regular basis.
