Join the AMA

Extreme off-road tests a riders’ skill and their machines’ capabilities over the most challenging terrain each venue has to offer, including agonizing hill climbs, endless rock fields and log crossings. The format is wide open for host organizations to include as many challenges at riders as possible. Extreme off-road can feature Le Mans starts, timed sections, GPS navigation, course changes and more.

Grand Championships

One of the toughest and most prestigious extreme off-road events in the nation serves as the AMA Extreme Off-Road Grand Championship.

National EnduroCross Championship

This is a six-race series organized by Cycle City Promotions. The events are moto-based, with heats and mains. The man-made tracks feature obstacles, including logs, rocks and water crossings, along with more extreme obstacles, such as K-rails and tractor tires. The courses vary in length in each round and cover extremely difficult terrain. Riders race head-to-head for a chance to win an AMA National Championship at the end of the season. EnduroCross is a one-day program featuring classes for Pros, Amateurs, Women and 35+ vets.
