Mark Barnett was the dominant AMA 125cc motocross racer of the early 1980s. “The Bomber” won three AMA 125cc National Motocross Championships from 1980 to 1982 and proved his versatility by winning the AMA Supercross Series in 1981. When he retired from racing in 1985, he was the all-time win leader in AMA 125cc Motocross history with 25 national wins in the class and was second to Bob Hannah on the all-time AMA Supercross wins list with 17 stadium victories.
In addition to his four AMA championships, Barnett also had success on the international stage as a member of the winning 1983 Team U.S.A. Motocross and Trophee des Nations squad. He twice won the 125cc U.S. Grand Prix of Motocross.

I loved Mark Barnett. I remember reading that he started designing and building tracks after retired, but I haven’t a clue what he’s doing these days. Do you, Larry?

The last time I talked to him he living in Alabama and was building tracks. He built RC’s practice tracks. He also was doing work in the Supercross series. Not sure if he’s still doing that.

Oops! Forgot to mention that his last year (or maybe it was two years) was on a Kawasaki. I pulled for him no matter what he rode, but he just didn’t have it anymore.
