I know some local restaurants/bars in my area have bike nights. Would you take your Ryker to one?

Yes I would.

NO,no and no . Most every Bar with bikes outside is a Harley hang-out. They hate everything not a Harley . (in my experiences.)
A closed mentality. (unless things have changed)

Yes, but most if the bike nights around us have all makes and models. I already avoided the places with attitudes

Definitely! There are good and not so good. Find your people;)

I would go there in a car first, as a casual by-stander, and get a feel for the place before making a decision.

Most definitely!

I’d say this depends on what kind of bike night and also who is going. A older person that went to a three wheeler gets different reactions than a younger person with one. I have not even bought mine yet and I have got the “bike with training wheels comments” lucky for me I got thick skin and have never really cared what ppl think.
