I had an avon storm on my k8 vee when I bought it, had no problems with it at all and going by the paper work I got it had done over 10000 miles. so when it came to replacing it I got the avon storm 2, again no handling problems but seems to have squared off after 7000 miles, although to be honest most of them have been 2 up and I'm no skinny minny (not yet anyway)
