Guennady Moiseev (pronounced gennod-ee moy-se-ehv) made his first mark in the 250 World standings in 1969 with a tenth place, directly behind teammate Vladimir Kavinov. It was a promising start, but it was followed by years of frustration. It took Guennady Moiseev four years to get back in the top ten (during this time Soviet racers Vladimir Kavinov, Alexi Kibirin and Pavel ,Rulev were making their marks in the points standings). Moiseev was floundering. But that soon changed. In 1973 Moiseev was fifth (Hakan Andersson was World Champ). In 1974 Moiseev won his first 250 World title (Czech Jaroslav Falta was taken out at the final Grand Prix by Moiseev's Russian teammates in one of the GP's darker title fights). Nineteen seventy-five saw Moiseev fall by the wayside with injuries (Harry Everts won the title on a Puch). In 1976 Moiseev won more motos than anyone else but lost the title to Heikki Mikkola. Nineteen seventy-seven was a banner year for the Russians as Moiseev and Kavinov went one-two. The following year was Guennady's third 250 World Championship year, and 1979 was the last time the now three-time 250 World Champion made the top ten, finishing fourth.
Kenneth Leroy Roberts (born December 31, 1951 (1951-12-31) (age 57) in Modesto, California) is a former motorcycle racer and the first American to win the 500cc Road Racing World Championship.
Roberts won two AMA Grand National Championships in 1973 and 1974, three consecutive 500 cc World Championships in 1978, 1979 and 1980 along with three victories at the Daytona 200. He is the father of the 2000 500cc World Champion, Kenny Roberts, Jr., the only father and son duo to have won the title.
Roberts is regarded as being one of the first riders to use his knee to balance the bike on the track in corners, and the first to use engine power to spin the rear tire exiting bends to help steer the bike (a technique known as "throttle steering", common among U.S. flat track racers). These techniques are used everywhere in the top levels of motorcycle road racing, though they are much less exaggerated with today's improvements in tire technology.
