Italian rider Nello Pagani won the 500 cc race riding a Gilera from Arciso Artesiani and Bill Doran.

Despite Dario Ambrosini winning the 250 cc race, a fourth-place finish for Italian Moto Guzzi rider Bruno Ruffo was enough for him to win the 250 cc championship, the only championship in the first season with results close enough to be still in doubt at the final race.
