Pengelly - Australian 500cc Champion for a week

Victorian Maico rider Jack Pengelly was one of Australia’s fastest and most popular riders never to win an Australian Motocross Championship.  But in Pengelly’s case, he came agonizingly close and was actually crowned the Australian 500cc Motocross Champion in 1973 for a week.

That year the Championships were held at Foster Park, Mulbring in New South Wales and the chase for the 500cc title came down to two Victorian riders – Pengelly on a Maico and Trevor Flood on a Yamaha.

Flood, the reigning 500cc Champion, switched from Bultaco to the a new Japanese Yamaha, being signed up by Milledge Yamaha in June. He rode a supply works replica YZ360 machine, which arrived in time for the Australian titles. It was the first Yamaha to be built as a motocross bike rather than a tricked-up trail bike.

Flood clearly was the fastest 500cc rider on the day and finished first ahead of Pengelly and another Maico rider Jim Scaysbrook, from New South Wales. But the stewards excluded Flood for “changing bikes” in between races and awarded the Championship to Pengelly, his first National title.

There was confusion between Flood’s 500 win and when the gearbox on his YZ360 blew (as they often did) when he was leading the Unlimited heat race.
Between races he changed the motor, then went out and won the 500 title. The investigation revealed, however, that Flood did not change bikes in the 500cc class, so he was given the title again – relegating Pengelly to second.

Pengelly was twice a Runner-up Australian Motocross Champion, earlier finishing second on a Montessa to Gary Adams (VIC, Bultaco) in the 250cc class at Tivoli Park, Ipswich (QLD) in 1970.

In 1977, Pengelly finished third in the Australian 500cc Championship at Acusa Park in South Australia, behind Western Australian Graeme Smythe (Yamaha) and local David Fulston (Husqvarna).  The year before in Ipswich (QLD) he was third in the Unlimited Australian Championship behind the late Trevor Flood (VIC, Maico) and Geoff Worrall (NSW, Suzuki).
