Pedro, go back to MCE and tell them your cheapest quote, they'll beat it
Tell them if they dont charge for your change of address then you'll stay with them. You'll have to pay a cancellation fee anyway
EDIT: Alternatively, I did a search on google for "we will beat any bike insurance quotes", spoke to CIA, i got their first quote down from 856 to 602 with no deposit to pay

was all for, knowledge purposes though. Couldnt be arsed with fannying about!
