Join Biltwell in the beautiful foothills of the Mojave desert just outside Ridgecrest, California, for the annual Biltwell 100 Desert Race. All riders on all bikes are welcome and they’ve got a wide array of classes for old bikes, new bikes, expert racers and first-timers alike.

There are entry opportunities for a variety of bike classes, including scramblers, dual sports, ADV bikes and even mini bikes.

This year the Biltwell 100 will also feature two new classes:

British Desert Sled: 1980 and earlier British Motorcycles. This is a combined class where men and women are scored the same. 

Otto’s Junkyard Challenge: New for 2026! Build and race the cheapest pile you can! One lap only. After the race, any of the other riders in the class can claim your bike for $750. This is an invite only class, you’ll need to submit your POS bike/plan to us and agree to post some build process pics and videos on social media. 

All bikes must have CA green or red OHV sticker or current street legal registration.
