Wonder why Kenny Roberts is King?

by James Pratt

WOW, just watch this. Former world champion Kenny Roberts is riding the much feared Yamaha TZ-750 2 stroke dirt track racer at the 2009 Indy Mile. It has twice the horsepower and 1/2 the weight of the Harley’s, with a hair trigger throttle and a narrow 2-stroke powerband. Even current world champion Valentino Rossi was left with his jaw agape after witnessing this spectacle!
