In 1975 Kenny Roberts(AKA King Kenny) rode a flat-tracker powered by a two-stroke Yamaha TZ750 four-cylinder to a dramatic victory, passing the Harleys on the last lap to take the win on a bike that many, including Roberts, considered too powerful to ride. To this day, Roberts calls it “the best individual ride” he ever had. And to commemorate that win — the only victory for the two-stroke machine — Yamaha put Roberts back on a TZ750 flat-tracker in 2009 and had him do a few laps at the Indy Mile.
Although Roberts hadn’t been on a bike in more than a year, he showed no signs of rust as the two-stroke wailed away and the bike drifted beautifully through Indy’s turns. This video contains original footage of Kenny working the high groove back in 1975, plus some excellent footage from that special event in 2009, which was attended by none other than nine-time world champ Valentino Rossi.
