The biggest indoor dirt bike series in the world: seventeen Saturday nights in NFL stadiums from Anaheim in January to the Salt Lake City finale in May. The 250SX class splits into East and West regions that meet only at the Showdown.

The post-season that settles SuperMotocross. Points from Supercross and Pro Motocross carry into three September rounds on hybrid tracks that blend stadium and outdoor sections, with the title decided at the Final.

National championship vintage motocross, contested on a period-correct grass track with table-top jumps as one discipline of the AMA Vintage Grand Championship, run each year during AMA Vintage Motorcycle Days at Mid-Ohio Sports Car Course. A single annual multi-day weekend event (not a multi-round series). Class winners are recognized as AMA Vintage National Champions, alongside sibling disciplines road racing, hare scrambles, trials and a round of the AMA Vintage Flat Track National Championship Series held nearby at Ashland County Fairgrounds.

The biggest amateur race in the world, and the one every American pro has ridden. Six days at Loretta Lynn's Ranch in Tennessee, 1,500+ riders across 36 classes, all of whom earned their spot through a nationwide qualifying process.

Statewide Ohio county-fair motocross series (8 rounds in 2026) run by promoter VIVA Ohio MX, one round per county fairground across northeast/central Ohio. Same OMXA-membership requirement and organizer as VIVA's Driven MX Motocross Series, which runs alongside it.

AMA District 12's under-the-lights companion series to the D12MX Stateline Championship Series, run at the same two host tracks but as its own distinct points program (a rider can run one, the other, or both). It alternates almost every week between Delta Raceway in northwest Ohio and Milan MX (on the historic Milan Dragway grounds, formerly Twisted MX / Milan Cycle City) in southeast Michigan. The 'border' in the name is the Ohio-Michigan state line the series straddles. 20 rounds in 2026, night racing under lights for rounds 1-18, then two Saturday full-track double-points rounds (Milan Round 19, Delta Round 20 as the finale) to close the season instead of the usual evening card.

Northeastern-Ohio/Western-Pennsylvania club running near-year-round racing across Motocross, Harescramble and Flat Track. Its motocross calendar is a 21-round 2026 season across four club tracks.

AMA District 12's flagship 13-round 2026 championship across Northern Ohio, SE Michigan and NE Indiana, titled the River Raisin Powersports Kawasaki Stateline Championship Series. Only Round 6 (Tri-State Motorcycle Club, Butler) is in Indiana; the rest are Ohio/Michigan.

AMA District 14's own multi-round enduro championship, run as a separate 'ENDURO' division distinct from the district's motocross division. Requires D14 membership to score points; best 6 of 7 events count, minimum 5 events for year-end eligibility. Seven rounds in 2026 across host clubs in Indiana, Michigan and Ohio.

House youth/mini series run on Delta Raceway's dedicated Junior MX track, distinct from the venue's D12MX-branded Battle of the Border (Saturday night) and Stateline (Sunday day) series and from the separate Friday-night Delta Pitbike Poker Series at the same park. Ten rounds run roughly every two weeks from mid-May through Halloween weekend 2026, each a single Saturday afternoon session (7am-3pm). Round 4 falls on Jul 11, 2026. Rounds 1-7 are listed with their dates on deltamxpark.com and on the track's iRaceReady series-points page.

Friday-night pit-bike house series at Delta Raceway, run the evening before most of the park's other weekend series (Jr Track Championship, Battle of the Border night racing). Riders build a season-long poker hand across the rounds they enter; per the event listing, a rider must compete in at least 6 of the 8 scheduled rounds to remain eligible for the season-end pit-bike prize draw. All 8 rounds of the 2026 season, spanning mid-May to end-October, are individually dated on deltamxpark.com's own event pages.

Racing requires an Ohio Motocross Association (OMXA) membership. The association's old site, omxa.net, is now squatted and redirects to a gambling site, but its membership requirement lives on through this promoter series.
