Yes..bit your lip, Lloyd.. I know how you felt, since insulting the instructor's choice in bikes, is just about the dumbest thing one can do.
Just consider the source...they are green at riding..but want to pretend they are experienced, and knowledgeable. ...But they are just boastful braggarts at heart.
Here in NY we have the standard motorcycle proficiency tests; however since the 3 wheel Can Ams have come along, the dealers can now offer special classes for them.
I believe it is just a morning class, followed by certificate. I guess I can understand that better, when one considers that most have a regular driver's license, and operating a Can Am, is more like driving a small car, rather than a bike.
