 At the end of 1957 the Italian teams quit Grand Prix racing citing increasing costs.In November 1957, with racing over, McIntyre rode a 350 cc Gilera racer around the banked circuit at Monza in an attempt to break the one-hour speed record, and he averaged on the bumpy Monza surface.This record was not bettered until 1964, by Mike Hailwood at 144.8 on an MV Agusta, on the track at Daytona.
