The first Lucas Oil Pro Motocross Championship race was held at Hangtown on April 8, 1974, with Bill Grossi winning the 450cc class on a Honda and Marty Smith capturing the 250cc class crown also for Honda.
Bill Grossi was a tire-spinnin', mud-chewin' factory rider for Honda, Kawasaki, Suzuki and Husqvarna.
"The Kid" Marty Smith also won the first ever 125cc Motocross Championship race at Hangtown. The year that Marty achieved his first major victory in the Hangtown Motocross Classic he was still in high school. He made history by being the youngest rider to earn an AMA Motocross Championship title.
Hangtown enters its 45th year as a motocross national. It is the oldest race on the schedule.
Seven different countries have been represented on the starting gate across both the 250 and 450 Classes.
