421 MX (MX 421)

421 MX in Yadkinville, North Carolina runs two tracks: a one-mile main motocross track loaded with tabletops, whoops, and multiple jumps, plus a separate arenacross-style track on the same property.

The two-format setup covers both sides of modern riding. The one-mile main handles traditional outdoor motocross sessions, and between the tabletops, the whoops, and the jump variety, it covers most of the technical vocabulary a developing rider needs to work through. The arenacross track brings supercross-style features for riders sharpening race technique, so you can train outdoor speed and short-format precision without leaving the property.

Prep is taken seriously here. The track is regularly groomed and watered, and consistent surface management is the difference between dirt you can train on and dirt that becomes the limiting factor by noon.

Hours are Saturday and Sunday, 12pm to 5pm. Riding runs on a small yearly membership fee, which keeps the gate accessible while funding the maintenance. The track sits in the same area as Thunder Valley Motopark, part of a cluster of Yadkin and Surry County riding options near Winston-Salem; 421 MX is the pick if you want motocross and arenacross on one property.

For riders in Yadkin County and central North Carolina, including Yadkinville, Boonville, East Bend, Mocksville, Mount Airy, Statesville, and the US-421 and I-77 corridors, 421 MX is an everyday option. Winston-Salem riders head west on US-421, Charlotte riders come north on I-77, and Triad riders from Greensboro and High Point make the trip for the dual-format riding.
