Apparently Bridgestone were developing a disc-valve 500 Triple when the company decided to abandon the manufacture of motorcycles. Could have been serious competition for the Kawasaki H1, though they probably would have run into the same problem that MZ did when they built their 125 Triple, feeding the centre cylinder. Assembly wouldn't have been easy either, so perhaps the end product would have been an enlarged GTR. Either way it would definitely be on my wish list.
