Yamaha's Ricky Johnson and Jeff Ward are the big winners at the Suzuka Supercross, a precursor to the Tokyo and Osaka Supercross races which will begin to flourish in the later eighties.
Riding for Team Yamaha, RJ will win 2-1 in the 250 class to top Team Honda's David Bailey, Kawasaki's Billy Liles, and Honda's Bob Hannah.
In the 125 class Kawasaki's Jeff Ward will top his Honda's Ron Lechien for both moto wins.
Suzuki's Gerrit Wolsink wins the Trans-AMA at Orlando Sports Stadium. Wolsink is a known sand-master, though by this time U.S. fans know him as the winner of the '74 Hang-Ten 500cc U.S. Grand Prix at the baked, hard-packed Carlsbad Raceway, where Wolsink will actually win five times in six years. Wolsink's Carlsbad wins not only made him famous in America, they kept his better-known teammate Roger DeCoster from ever winning the USGP. DeCoster is the runner-up at Orlando.
The 250cc Support class at the Orlando Trans-AMA and series title will go to Team Honda's teenaged sensation Marty Smith, already the AMA 125cc National Champion.
