Designing and Building the World's Best Tracks

The Anatomy of a Supercross Track

A Supercross track represents the ultimate evolution of the sport.

The Whoops – Typical height is 3 feet.
Finish Line Jump – There are usually 9 different structures built for every track; finish line, podium, team manager tower, scoring tower, holeshot structure, starting gate, AMA finish-line scoring tower, observation tower and the video wall.
Triple Jump – A triple jump is 70 feet long and 35 feet high.
Rhythm Sections – Includes multiple obstacles to include table tops, dragon’s back and an assortment of doubles.
The Starting Gate – 22 gates, 80 feet wide, the straight is typically 150 – 375 feet.
Sand – The ever changing line here is a challenge to even the best riders.
Rhythm Sections – Includes multiple obstacles to include table tops, dragon’s back and an assortment of doubles.

Among the many obstacles riders must negotiate every lap are whoop sections (brutal washboards where riders skim along the tops of the bumps), rhythm sections (irregular series of jumps with a variety of combination options), and triple jumps (three jumps in a row that riders normally clear in a single leap of 70 feet or more).
