We noticed a quad bike passing buy so my mate asked where you would insure it? Quick search on the net revealed that they are treated as cars not motorbike. Still checked some sites and could not find one car or bike insurance company that would quote for quad bikes. Does any one here have one on the road and would share where you are insuring it and maybe how much?
Most insurance companies will cover them these days, but they wont be listed on comparison sites or web sites. You will need to contact them for a bespoke quote.
