Up here in Vermont we Spyder owners are told, 2 wheels = motorcycle, 1 wheel in front, 2 out back = trike, 2 wheels in front, 1 out back = 3 wheeled motorcycle. Go figure!
I have a Suzuki Burgman the 650 AN Executive and I also have a Spyder RT Ltd. I once had a Piaggio MP3 400 and I thought it was pretty good - I only had it for a short time hoping my wife would get the big but she didn't. I think if I were to replace the Burgman I'd look for a Piaggio MP3 500 - they have just a bit more grunt than the 400 and the three wheels as you'll find with the Spyder is much more stable. The wheels on the 3 wheel scooters are much closer together then the Spyder but still the extra traction is reassuring.
