First 500cc GP machine with V-4 engine
This was the first GP500 machine to mount a 2-stroke V-4 engine, and it featured a frame structure that eliminated the under-loop that connects to the Deltabox frame and a rear suspension mounted under the chassis lateral to the direction of forward motion. Full of innovative mechanisms and components, the 0W61 became the base model for ensuing development. Its debut came at the second round of the 1982 series, the Austrian GP, where K. Roberts rode it to a 3rd-place finish. Its first win came at round four round four, the Spanish GP, but it fell short of winning the season title.
