Need to understand that maxi-scooters are not what most people think of with the term scooter. Engine sizes up to 800cc and speeds well over 100mph and come with comfort for all day riding. They are suitable for freeways or mountain twisties. BMW just came out with a couple great ones. Yamaha T-Max, Honda Silver Wing and Suzuki Bergman are all serious rides. Most modern scooters are automatic with rear brake by left hand. They will run with the big bikes most anywhere.
I have ridden 85,000 miles on a couple of MP3s. Few 2 wheel bikes can keep up with my 400 cc on twisty roads. It is a great ride but don't let the 2 front wheels lead one to think they won't fall over. They lean like any bike, are heavy. The front suspension can be locked only when stopped so no kick stand is needed.
