I recently went from one Virago 1100 to another. They are identical except my new one is 9 years newer, 25 kilos lighter (according to the specs) and 7 hp more powerful than my old one. The rego on my first 1100 said LAMS was not allowable, and fair enough, being a biggish engine. I recently got the new Rego certificate for my new bike and believe it or not, it is LAMS approved! I rang Dept of Transport who told me this was right, but I am puzzled as to how this can be, even if its based on "power to weight ratio". I thought LAMS was for bikes under 650cc....if I had known I could ride this bike on my RE licence, I would not have needed to go through the test to get my R (although Im glad I did).
