Gilera Saturno 500: history and buying advice
Sporting 500 cc single from Arcore.
History
The Saturno was designed by Giuseppe Salmaggi and presented in 1939. Because of the war, real production only got going afterwards; it left the factory in Arcore, close to the Monza circuit, until 1959.
There were Turismo and Sport versions, a racing version nicknamed Sanremo and later a Cross version for motocross. Gilera’s world titles in the 500 cc class were won with the four-cylinder; the Saturno was mainly successful in national road racing and off-road.

What to check when buying
- Turismo, Sport or Sanremo? Compare frame and engine numbers with the papers; replicas of the racing and cross versions exist.
- The long stroke gives plenty of pulling power at low revs: it should start easily and idle calmly.
- Look for oil leaks and whether the lubrication system is clean; ask about the last rebuild.
- Rear suspension with horizontal springs: check for play in the swinging arm.
- Parts are scarce: expect to search through the club and specialists.
