Cheers matey.
My insurers will cover me and another bike, but they won't cover a Monster

Because it's classed as a roadster i.e. a different style of bike they won't cover it. Bizarre, as the bike is less power and worth less cash than my 749S!
I'm waiting to see what else DM can offer me, and it looks like they've just sold the Monster I was going to have anyway!
