Trikes and stability.
The physical forces that come in to play on a trike are substantially different than those that come into play on a two wheeled vehicle. One reason the three wheeled dirt bikes are no longer made is there instability and desire to roll over the rider when ridden above safe limts. One nice thing about triked road bikes IS their weight. Tends to keep the three wheels on the ground.
Riding a trike becomes second nature much like a motorcycle does with time and experience. I think the video that the company that makes the additional two wheel setup does a pretty good job of addressing the differences.
Trikes have also allowed many people that could no longer handle the weight of motorcycles, due to injury or illness, to once again take to the road with their knees in the breeze. I have met many very nice folks on trikes that otherwise would not be able to enjoy their passion.
In Washington state, because of the signifcantly different handling characteristics, a trike endorsement is required of any state residents to operate a trike in the state.
If getting a trike gets you out on the road amongst the rest of the riding public, by all means make the switch!
My current motorcycle weighs in at 875 pounds wet. Put me in the saddle and it quickly surpasses the half ton mark. The bike is designed with fairing extentions that will not allow it to fall over flat on its side, it always lays over at an angle, usually with both wheels in contact with the pavement. It goes a long way in making it possible for me to lift the bike if dropped by myself using the proper technique. The first time it went over was within a month of purchase. I didnt have the side stand locked in place. Jumped off the seat and as I reached for the pump handle, heard the ugly sound of a bike rolling over on its side. Flat and level pavement made lifting it much easier than I had envisioned.
Tis not what you ride, but the fact that you do ride that matters!
