Take the MSF class on two wheels, and get your endorsement that way... Then just jump on the can am and take off! The two wheel class is well worth the time, money and knowledge you learn about motorcycles in general. Also it makes you more aware of the road, and helps you drive your car differently, with more respect for the road and especially motorcycles.

If for some reason you fail the test after the MSF class, no worries they usually let you take it again for free, or you abandon that and go take the road test for trikes... Either way, you gain valuable lessons and information about motorcycles. My 2 cents.
