Ducati is, in many ways, like the Ferrari of motorcycles. They're both Italian, look good in red, and can be expensive to maintain. They both also passionately appeal to all your senses, with their glorious sounds, performance and sexy good looks. The Ducati brand carries some heft. And there are certain elements that are considered core to their brand, like the 90 degree V-twin engine and Desmodromic valvetrain.
Over the decades, Ducati produced a variety of engine types, including singles, parallel twins, and V4s, but on March 20th, 1970, Fabio Taglioni made the first sketches for the layout of a new Ducati V-twin engine. His drawings were complete in one month, and by July -- a mere 4 months later, there was a running motor. By August, there was a complete prototype motorcycle, and by October they were compelled to re-enter motorcycle competition with their new set-up. Six months. It was their first V-Twin desmodromic engine. The layout they are best known for to this day.
