I don't think the BMW or Wing trikes are getting any better than the RT. This is not a motorcycle and you are driving another wheel and have more wind resistance.
That's a good point. Since I wouldn't consider a trike in my future, I never thought about them. The Sypders are just so unique that I wouldn't mind owning one and keep comparing them to what I'm used to riding.
As far as being hardwired or bluetooth you can still run a bluetooth system independent of the RT. You can use a bluetooth through the Garmin 660 too if you want to use the phone or listen to music.
True, you can, but some Bluetooth systems won't do intercom. I guess my point was, if you're going to throw technology into a "bike", why not go whole hog and make the comm system as techy as the rest of the bike.
