They are good, but not particularly exhilerating to ride.
Last year I took a class (BRP does discounted sessions, $75 for two days) where they provide various models of can-am to participants. I was mostly attracted to the styling and was imagining doing a west coast road trip (Seattle to San Diego) if I got convinced enough after the class.
I wasn't. But that could probably be because I already ride 2 wheeler (Triumps Street Triple or Yamaha FZ09) and these things do not even come near to fun factor of a proper motorcycle. However they do appeal to a particular section of buyers who had to end up giving riding for health reasons or are just not comfortable riding 2 wheels.
I have to say, these are very comfortable even in their sportiest configuration and can be made super comfy by adding sofa like seats.
I ended up not buying it but one day when I am too old to balance properly on 2 wheels I will definitely consider these. For now I am ok with loud and bats**t crazy nakeds, no matter how uncomfortable they are (compared to canam). Thanks to that class though, I passed my exam and got the endorsement to ride trikes.
Edit: I rode Canam F3 for the class. It looks significantly different than the one pictured above. Just imagine taking the one in photo and stripping most of the plastic you see.
