We’ve divided the vintage classes based on era/style of bike and rider skill level as usual. Men and Women in the same class (Dual Shock Novice for example) will generally start at the same time but will be scored separately.

The Modern classes are determined by age group. Men and Women in the same class (Modern 18-40 Novice for example) will start at the same time but are scored separately.

ADV Lite and Heavy classes are meant to include riders on adventure bikes that didn’t fit neatly into previous classes. Men and Women in the same class (ADV Lite Novice for example) will start at the same time but are scored separately.

Thanks to Mike Davis for organizing the Early Iron class for 1960 and earlier American Motorcycles. This is a combined class where men and women are scored the same. An even tougher version has been added now – Early Iron Endurance which is the same rules but is twice as long – two laps!

Pull-start minis get their own class since this is SO competitive now! Pull-start engines can be any size as long as they are only started with a pull-rope mechanism.

Any Harley over 750CC is in the Hooligan class and only racing other Harleys.

All classes get a trophy for 1st, 2nd and 3rd. Total number of entries is capped at around 350 racers. This event will sell out, so once we open registration you should go for it. Entries will go on sale Jan 15th, 2024. Watch Biltwell social media for more last minute updates.


  • No class changes will be permitted at registration.
  • Racers may enter only one class.
  • No “team” riding. One rider, one bike, per entry.
  • Classes may be mixed at starting line but will be scored separately.
  • The fastest classes will start first. Men and women in the same classes may start together but will be scored separately. Different classes may be combined to create a full row but racers will only be scored against riders in their own class. There will be a short break between each starting row.
  • A single lap is roughly 25 miles. Classes run between 1 and 4 laps depending on age of bike and rider.


  • Numbers will be given to you randomly at registration. This will speed up the registration process and avoid confusion on the course for manual scoring. We will provide you with big stick on numbers that can go over your existing ones and you can peel them off after the race. This is way better than pie plates, electric tape numbers or a dozen “69’s” on the course at the same time. Just go with it, and we’ll see how it works.
  • The pits and starting line will be same as 2023.
  • We’ve increased safety and organization after learning a few things in 2021. We will have a central phone number (bikes don’t have radios!) for broke down riders to call, with a dedicated dispatcher on-site to help get to you sooner. There will be a clearly marked Info + First Aid tent near the stage that will be equipped with EMTs, ice, first aid supplies, etc. We will also be supplying each racer with a “stuck stub” and will explain its usage to noobs during the rider’s meeting.
  • We’ve got more portable toilets and trash cans coming this year.
  • During the awards ceremony on Saturday night there will be cold beers and tacos while they last
