Paton 500 1976
There was talk of the Paton two-stroke in mid-1975. That year
Walter Villa was monopolizing races in the 250 class with the Harley-Davidson.
Giuseppe Pattoni had been thinking of replacing his fine two-cylinder 500
four-stroke with a more competitive motorcycle. Knowing that separate parts of
the Harley-Davidson engine were sold on the open market, Pattoni saw no reason
to build a new engine from scratch. He decided to save time and energy by using
parts of Villa's engine as far as possible.
Pattoni set out to build a four-cylinder, two-stroke engine in
which the cylinders were arranged in alternating V form and frontally in line,
with the two outer cylinders forward and the two inner ones back. This made it
possible for him to use the Harley-Davidson racing cylinders and rod system and
only build a crank-case for them. For the transmission Pattoni turned to the
Harley-Davidson 350 racer, and for the chassis he turned to Bimota.
The new Paton 500 made its debut in 1976 driven by Virginio
Ferrari. The first track trials were not altogether satisfactory, so Pattoni
took the vehicle back to the plant. It reappeared later in the year with a new
Segoni chassis and an improved engine. Mimmo Cazzaniga raced the Paton 500 at
Mugello and then went back to Milan to await the 1977 season.
