Arroyo Seco Raceway is a 1.4 mile purpose built roadcourse. For motorcycle use it can be run in either direction, plus it can also be run in a 1.1 mile configuration. This gives ASMA the opportunity to run 4 different racetracks! There are no trees, walls, or armco always used the 1.4 mile version, alternating between running the track clockwise and counterclockwise at every other event. Finally, a racetrack that doesn't need airfence!!! This makes ASMA events extremely safe for both trackday riders, who don't want to scratch their streetbikes, and racers, who don't like hitting immovable objects at racetrack speeds. Just pick the bike up and run off into the smooth desert instead of crashing when you miss a turn.
