Lot 033: c1952 BSA M21

BSA introduced a new range of singles in 1937 of which the M21 was one. It featured a lazy 596cc sidevalve motor with huge amounts of torque on tap and was squarely aimed at the sidecar market. Along with its close relative the 500cc M20 it was an immediate success, and continued in production through the war years and into the fifties, by which time the 'girders' had been replaced with telescopic forks. Arguments still arise between Norton and BSA men as to who made the best big 'sidevalves,' both marques offer relaxed motorcycling par excellence, and today's M21, which is described as in good condition throughout, must be a serious consideration for anyone looking for that lazy long legged thoroughbred
