It was quite an event as I recall, lots of advertising in the local paper and so on. I actually rode it a couple of times, once as part of a C-Grade team on an RM500 and once as a fill-in for a guy who had planned to ride solo but then decided he needed a short break. It's a bit hazy now, but I think his name was Mueller, he was an A-Grader from Townsville, and the bike was a Husky CR500. I think. Maybe...
Anyway, he was quick and was going real well. I managed not to lose too many places and he was looking good for a decent finish when the chain, a name brand, cracked every plate. He didn't prepare for that and it was race over. A shame.
The track got real hard by about the 2 hour mark and you could road race it then. I remember going through the big sweeper pretty quick, feet up and knee out. It was a fun race.
