I rang my insurer, just for a quote, to put my Fazer on the same policy as my blackbird... and was quoted cheaper than my current policy. So that's negative! Whoop whoop!
Hmm I had to think about that for a while
What is going on here is I think your blackbird is near top price and so adding the lower cc fazer is going to reduce the amount of time you are on the blackbird.
Question
Would there be anything wrong if you brought a werck for £50 and sorn it (so no cost there ) just so you coud add it to your policy - after all you do own it and will be fully regestered to you.
OK you may just brake even this year but next and thereafter you will be better off
