In the early 1950s, Gilera's racers that grabbed the headlines, taking six individual World Championships and five manufacturers' titles. Although, racing generated valuable publicity, it was the sales of road bikes that 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.

A matching-numbers example, this Gilera 175cc Racing Motorcycle was built for Italian street racing. Boasting a very expensive repaint, the machine is fully restored to full racing specification, the engine being rebuilt with a piston and works race-kit cams. Other noteworthy features include sand-cast engine cases, Dell’Orto 22.5mm carburetor and one-piece exhaust. Ideal for classic parading, the machine is presented in generally good condition.
