The horn is legal on that bike - it's a 1962 Triumph Cub Trials special. It has no electrics, apart from the ignition directly from the alternator, so no electric horn would work! Besides, anyone who couldn't hear the bike coming deserves to be hit - there are no baffles in the exhaust and the engine clatters very loudly too. My TTR is a Rolls Royce in comparison. Martyn
