Gear components from BENELLI—high-quality Gear Cogs and transmission parts from a small Italian manufacturer with a long tradition in motorsports.

Since the 1980s, Stefano BENELLI has been passionate about all kinds of gasoline-powered vehicles, whether two- or four-wheeled. This passion was particularly strong for 2-stroke engines and, of course, for the Vespa. He gained his first tuning experience here, and his designs were already being raced in the earliest Italian drag races. Soon, the original design of the Vespa transmission was overwhelmed by the increased power.

Even back when only a short 4th gear was available in Germany for Vespa small-frame models, the Italian racing elite was already using transmission components from Stefano BENELLI. In recent years, more and more transmission manufacturers have entered the market. Outside of Italy, however, BENELLI’s products were hard to come by and known only to a small circle of people.

Yet his products have a very good reputation. In material tests conducted in Germany, his Gear Cogs ranked among the best. Today, BENELLI is a small manufacturer that produces mechanical components for a wide variety of applications using the finest materials. These components are successfully used in motocross, circuit, and drag racing.

The BENELLI water-cooling Gear Cog can be used to drive mechanical Water Pumps on the QUATTRINI Crankcase for Vespa small-frame Models.

The gear cogs are specifically designed for use in QUATTRINI crankcases.
