Dave King can sell you a copy of the famous 1989 500cc GP at Namur with Leisky putting it to Geboers and Thorpey - its one of the best races I've ever seen, and shows the big 2 bangers in action at their very peak of development.
Leisk was clearly the most talented Aussie never to win a world championship. I look forward to meeting him at a future Classic Dirt.
