Rex Staten (#24) almost won the 1st 500cc Moto after hole-shotting, but his engine mounts broke and he faded to 7th. Gerritt Wolsink (#4) took the overall win.
Highly recommend reading about the development of Rex Staten's bike for this race, "Building and Racing the Fastest CZ400 on Earth" by his mechanic, Harry Klemm.
