What are the cheapest bikes to insure?

I'm not totally well versed on the subject, but i know for a fact the cheaper insurance goes to:

older bikes

bikes with lower cc's and less power

bikes kept indoors (to make theft less likely)

bikes with alarm systems (again with theft)

bikes belonging to people in safe neighborhoods

bikes belonging to people with safe jobs (if you park at a construction site your insurance will be more)

so the bike itself isn't the main issue, but the less flashy and powerful the bike, the cheaper the insurance, but many other factors come into play
