I worked at a Honda dealer in Vero Beach Fl. when they introduced the atc 90. We set the first two up as demos and spent every weekend at Hobart Park (about 2 square miles of sand dunes and a few wooded trails) where we first learned what they would and would not do, then made every effort to instruct customers on what we learned. Some learned and some did not. It was a sad day for me when those who would not or could not learn brought about the end of the 3 wheeler. Quads are far more stable and versatile. They should have been an addition instead of a replacement. Having learned to ride on a 3 wheeler I will always miss them. My advice to any new rider; the biggest safety issue with any machine is the operator, know the limitations (yours and the machines) and last you will never be it's master treat it with respect or it will bite you. Ride safe and never stop learning.
