Gilera 175 Regolarità Super Sport 1956

Throughout the early 1950s it was Gilera's road-racers that grabbed the headlines just as they had in pre-war days, winning the 500cc World Championship on no fewer than six occasions between 1950 and 1957.

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.

Regolarità (Regularity) 'Six Days' enduro models were offered in 98cc, 125cc and 175cc capacities, all equipped with the necessities for off-road competition: 21" front wheel, 'knobby' tyres, upswept exhaust, wide handlebars and generous ground clearance.
