Vintage Yamaha RC100 Racing Kart

Yamaha RC100 Racing Kart Produced by http://vintagepowersport.com A mint restored RC100 show piece as seen at Adams Kart Track in Riverside CA during the January 2010 Vintage Karting Association event. For a couple of years in the late 70's, Yamaha sold this complete kart racing package in the USA, kart & motor ready to race. Unfortunately the kart was unsuccessful, the chassis proved to be uncompetitive with other chassis's of the era, and kart racers have always preferred to select and combine components as opposed to buying a complete package. The KT100 Yamaha engine which was lower in power than other 100cc foreign motors of the day, went on to become the most popular kart motor in US kart racing history. This was due to several reasons: it was a low cost motor, McCulloch had stopped making motors, and because the IKF & WKA defined KT100 only racing classes. KT100 kart racing classes are still popular today in the USA.
