Delia Ferrera 500 Record Racer

 

 

 

From his early youth Federico Delia Ferrera had a passion for mechanical things.
His great dream of becoming a motorcycle manufacturer began to come true about 1910. He started out with a small four-stroke engine with head valves and a displacement of 498.7 cc. In 1914 Delia Ferrera built a racing motorcycle with a four-valve overhead engine, two-wheel brakes, graduated-speed gearing, and. front-wheel elastic suspension with a shock absorber.
The most famous of Delia Ferrara's racing motorcycles was his 1921 model. It had a two-cylinder, four-stroke overhead-valve engine, with single-shaft chain distribution.

This model, known as the "Cate-rina," was ridden by the young manufacturer (who had already made a name for himself as a racer) to a world speed record—the first ever for an Italian-built motorcycle. On the 114 straightaway of the dusty road between Orbassano and Bruino, Delia Ferrera, wearing a leather cap and goggles to protect his eyes from the dust, rode at the wild speed of almost 90 m.p.h. on his first attempt. On his second run he drove a little- more slowly. Therefore the official record for the top speed of the 500-cc. motorcycle was an average of the two runs, 139 km./hr. (about 85 m.p.h.).
