CAA membership for motorcycle only?

CAA covers you in Canada and Continental USA. They have contracts with most towing companies in North America and will take care of the cost.

They will never leave you stranded. They will find a towing company to assist you. You may have to pay and submit for reimbursement but, they tell you this before firming up the arrangements.

Even if you have the basic plan, they will dispatch service and advise you they will cover the hook up and first X number of miles/kms, and you are responsible for "extras". Special handling /flat bed requirements etc.

Can't answer for AAA but, it's very similar.

Pay for even one tow yourself and it's gonna be more than the $114 the Plus costs you. It makes sense to me that it costs more anyway, because it costs them more to deal with motorcycles than it does with cars
