BSA Model K 4 1/4 500cc Flat Tanker 1915
BSA Model K 4 1/4 500cc Flat Tanker 1915. Looks to be in fantastic all original condition which is incredible for a motorcycle which is 108 Years old! Starts, runs and rides well with Superb Bonniksen 100 mph Time & Speed meter. Comes with some nice history which includes its original buff card log book. A very rare machine and great fun too!
