Throughout the early 1950s it was Gilera's road-racers that grabbed the headlines as they had in pre-war days, winning the 500cc World Championship on no fewer than six occasions between 1950 and 1957. But although racing generated valuable publicity, it was sales of road bikes that paid the bills. The majority of machines sold were lightweights based on the overhead-valve 125cc single that had appeared in prototype form in 1948. Developed and enlarged first to 150cc and then 175cc and beyond, these simple OHV singles proved top sellers throughout the 1950s and 1960s. Following its withdrawal from Grand Prix road racing, Gilera turned increasingly to off-road competition, principally the International Six Days Trial, as a means of keeping its name in the public eye. New owners Piaggio supported this policy, and throughout the early 1970s Gilera's Regolarità (Regularity) two-strokes were the equal of the best in their class, winning the European Enduro Championship in 1973.
Before then though, the Arcore firm had relied on developments of its traditional single-cylinder four-stroke roadsters, such as the 175cc five-speed model offered here. 'Six Days' enduro models were offered in 98cc, 125cc and 175cc capacities, all equipped with the necessities of off-road competition: 21" front wheel, 'knobbly' tyres, upswept exhaust, wide 'bars and generous ground clearance. Offered with Italian papers.
