Most of my carbon fiber came from AF1 racing in America. The overall quality was excellent and the weave was awesome and in my opinion far better than the OEM ones supplied by Aprilia. I'd recommend them to anyone especially at the current exchange rates at the moment, but do expect to be hit by the Tax man on the way in. I also got some from Europe, (Germany if I remember rightly) When I was trying to get mine, the bike had just come on the market & there was very little decent on the market which made me look further afield.
