Erv Kanemoto

Erv Kanemoto (born May 7, 1943 in Utah) is an American former World Champion motorcycle mechanic and motorcycle race team owner. The son of a farmer, he began boat racing as a child then switched to tuning karts raced by his sister.

Kanemoto was hired as a race mechanic by Kawasaki in 1968 and became known for his partnership with motorcycle racer Gary Nixon when they won the 1973 U.S. Road Racing National Championship aboard a temperamental and brutally fast Kawasaki H2R, a 750cc three cylinder, two-stroke engine.

When Nixon retired in 1979, Kanemoto joined a young up and coming road racer named Freddie Spencer and won the U.S. 250cc Road Racing National Championship with a Yamaha. He spent the 1980 season with Spencer before moving to Europe in 1981 to be a Yamaha mechanic for former 500cc World Champion Barry Sheene.

He is perhaps best known for the World Championships won with Spencer for the Honda Grand Prix team in 1983 and 1985 when Spencer accomplished the double by winning both the 250cc and the 500cc Road Racing World Championships in the same year, a feat that will never be repeated due to the discontinuation of the 250cc and 500cc classes in current MotoGP competition.
