You will notice that the body of the RoadSmith kit has a small bit of lean. Make a few circles and figure 8's in a parking lot and you'll see what I'm talking about. You will feel that when you negotiate a curve, more or less, depending on the curve. It won't take you long to get used to that "feeling", and you'll come to expect it and look forward to it. To me, the trike feels like a sportscar in a curve, and the sideways G-force you will feel on the trike is the same as in the sportscar. You will be surprised at how quickly you will get used to the way the trike feels and handles, and I think you'll enjoy that just as much as the way you enjoyed your bike on two wheels. It ain't better or worse ... just different!
Personally, I'm glad the RoadSmith has that bit of lean to the body when turning or curving. It means I have more feedback from the machine that lets me know where I'm at as I negotiate these. I still lean to the inside of the turn or curve ... it's just natural to do so.
