Build year: 1956

In 1956, a 175 cc and 250 cc model was launched with a swing fork. After a year this fork was replaced by a telescopic fork and the two models received the addition "Trophy", because they won many Six Day races. The cylinder was slightly inclined forward and they had resp. 10.5 and 14.5 hp.
