To each their own, around town and shorter excursions (say under 300 miles a day) I ride my Vespa GTS 250. For longer trips I take either a Scarabeo 500 or BV 500. 3,300-4,600 mile multi-state trips are a pleasure. Didn't care for riding a Burgman so we traded it in for the BV 500.
Could I ride a motorcycle - sure, the ATV I ride is motorcycle shift so it isn't shifting that prevents me from riding on. I simply prefer the upright ergonomics of a traditional style scooter. If you prefer a motorcycle for long trips, have fun. I don't even if I occasionally look at certain bikes and think maybe ... but in the end I really prefer the step through frame.
