I would seriously consider a motorcycle and have been looking at getting a Royal Enfield...love the classic post-WWII look. And at 500cc, it is light and economical. However, I have a scoot because most of my commuting is in the city and that much shifting would be a pain. Also I have storage for my paperwork, the faring protects my clothes, and it is easy to maneuver. Then there is insurance.....$75 a year vs. $200+ for equivalent sized engine motorcycle - 250cc.
