Colorado Pit Bike Series
Club-tier small-bike (pit bike / mini-bike class) outdoor motocross series run by Black Diamond Promotions on its own dedicated site (coloradopitbike.com), presented by FactoryMinibikes.com. Requires a separate series membership plus per-round race-day sign-up. Runs at Colorado Front Range venues, IMI Motorsports (Dacono), Arapahoe County Fairgrounds, Jeffco (Jefferson County) Fairgrounds, Douglas County Fairgrounds and Colorado National Speedway, several of which also host Black Diamond Promotions' full-size supercross rounds and RMRA's amateur SX series on separate dates. Separate from the RMRA MX/SX series: different operator, different site, no shared branding.
Tracks on MX Tickets sell gate entry, practice days and camping online. Book before you turn up.
