Wow i either didnt shop around or live in a much worse area than i realise!
I'm 27, 2 years ncb, cheapest was MCE, £1k fully comp, with tracker and datatag... and it doesnt cost any more to add my vfr800 on too, which was a nice surprise!
i wouldnt worry, you get what you pay for, anyone who says that they are paying small premiums are either bending the truth, not fully comp or the policy is not worth the paper its written on
also third party fire and theft is a risk whether it be a car or bike.
