BMW factory records show that this motorcycle was completed on 28th May 1953 as an R67/2 model and sent to the Test Department to be prepared for that year's International Six Days Trial (ISDT) held in Czechoslovakia. West Germany's five-man Trophy Team was made up of two Maico riders (U Pohl and K L Westphal) and three entered on 594cc BMWs (G Meier, H Roth and W Zeller). Of the BMW riders, Hans Roth and Georg Meier (winner of the 1939 Isle of Man Senior TT for BMW) won FIM Gold Medals while the unfortunate Walter Zeller suffered a broken transmission bevel box – a previously unheard of failure – and was forced to retire. West Germany's Trophy Team finished the competition in 3rd place behind victorious Great Britain and runners-up Czechoslovakia. | BMW factory records show that this motorcycle was completed on 28th May 1953 as an R67/2 model and sent to the Test Department to be prepared for that year's International Six Days Trial (ISDT) held in Czechoslovakia.
