Rosco.

"Rosco McGlashan has been synonymous with the very peak of speed sport in Australia.

He raced the Australian designed and built 'Crazyhorse' V8 powered motorcycle. This was an incredible machine which had no clutch, so the back wheel would sit up in a cradle, then Rosco would give it a rev and just rock it off the cradle! "It spat me off a few times and when it spat you off it did it in a big way!" remembers Rosco..."
