Gilera 175 Super Sport 1956

Throughout the early 1950s Gilera dominated the headlines in the motorcycle press, taking six individual World Championships and five manufacturers' titles. Although racing generated valuable publicity, it was sales of road-going motorcycles which paid the bills. The majority of machines sold were lightweights based on the overhead-valve 125 single that had first appeared in prototype form in 1948.

Developed and enlarged first to 150cc and then 175cc, these simple OHV singles were top sellers throughout the 1950s and into the 1960s, although their high price outside Italy made them a relatively rare sight abroad.
