My understanding of motorcycle categories is that a bike exists in an insurance category, and that is a major factor in the insurance quote that you are given. Its a static thing and cant get increased or lowered on a stock machine. Who decides what bike goes into what category and how do they do it? Is it a federal or state thing that insurance companies follow or is it a corporate policy? Anyway, is there a site that lists the insurance categories of bikes so that you know how fleeced you may be before you submit your insurance quote? Insurance category is a huge factor when buying a bike, so it would be good to have a (very long) page containing category headings and a list of all bikes within each category. There doesn't seem to be any such resource in Australia from what I could see. Could we do that here? I would gladly contribute to such a list.
