If you search through the history, one of the other Guildford riders, Stu posted some pictures of a pair fitted to his faired bike. They look a lot better on a pointy than a curvy, but either way they keep your hands warm.
They are a genuine Suzuki part. I got mine from local dealer
www.Infinitymotorcycles.co.uk I expect any decent dealer will be able to get them for you.
If you manage to track down Stu's posting he had the part numbers too. If I manage to find my paperwork I'll add the part numbers to this thread.
