A local motorsport co. handles both the large slingshot, and a smaller unit called the CanAm. My local Legion has a Legion riders branch, and along with regular bikes and trikes, there are some of these newer style three wheelers.
In our state, motorcycles require a special license endorsement, and this dealer offers free classes to prepare the
potential CanAm owner for his license.
I haven't been interested in the large model, but did take a spin on one of the guys smaller CanAm model, which comes in either a 600cc and a 900cc engine.
I didn't see where it offered much gain over the scooter I already have. Besides, spending about $8k for one doesn't seem feasible. Perhaps in a more southerly climate, where it will be used more months of the year.
See smaller model below.
