I changed from a Tiger 800 to the Triple Black GS last October. When it came to renewal time last month i spent hours on the phone as it seems difficult to get multi bike quotes online. I should add that the other bike on the policy is a Victory Vegas Zach Ness which is a limited edition, so jumps up a catagory or two. I ended up insuring the pair fully comp, garaged at home, neither have an alarm and i'm 48, for £312, which i didnt think was too bad. I had quotes of anything up to £700+
Wicked Quotes is the company i used
