I'm not sure if this is the best place to post this, but here goes...

I'm seriously thinking about switching from a cruiser ('01 Vic) to a sportbike. I have always loved the look of the Ducatis and have been watching the ads on Craigslist. There have been what seems to me some pretty good prices lately on 748's. I am 40, 5'10" and could definitely stand to lose a few pounds. Just how comfortable would one of these be for me as a daily driver? Would I be crazy to even think about multi-hour rides on one? How expensive is maintenance?

Thanks for any answers you can give me on this!
