THE AMA WESTERN 4-STROKE THUMPER NATIONAL MOTOCROSS
If you have never been out to see an awesome AMA 4-Stroke Thumper National motocross race, or for that matter "HEAR" a thunderous AMA Western 4-Stroke National Motocross event take place, "Just do it". There have been events in Texas, Arizona, Colorado, Missouri, California, Oregon, Idaho, Utah, Washington and Nevada. Whenever you hear the roar of a full gate of thumpers power off the line, It's an Unmistakable, Unparalleled and a Unbelievable sound.
Since the evolution of this AMA Sanctioned series in 1996, following the closure of the AMA 500 Motocross Nationals, it has been a significant place for the ProAm racer aboard the "Big Bore" 4-stroke. They now have a forum to come out and enjoy the sport of motocross, by competing with machines that are not 2-Stroke.
Pros: Great content, Very informative, Thumpers Rule!
