South Fork Motoplex (formerly Blackrock MX)

South Fork Motoplex in Leitchfield, Kentucky was formerly known as Blackrock MX. The property is owned by the Carnes family, a long-running Kentucky motorcycle racing family whose pedigree in the regional racing scene is part of what defines how the operation runs.

Riders consistently call the dirt at South Fork some of the best in Kentucky. Loam mixed with red sand is the property's soil profile, and the mix produces the kind of varied surface that develops differently through a single session. Loam holds tacky lines through the morning, the red sand sections develop the kind of ruts that test sand technique, and the combination of soil types delivers riding character that single-profile tracks cannot match.

An elevated start is the property's signature track feature. Elevated start gates change how riders approach the first turn, and the natural elevation built into the layout reflects an operating culture focused on serious motocross construction. The mixture of soil types continues across the layout, producing the kind of riding variety that flat single-profile tracks cannot deliver.

Elevation changes and obstacles across the track give the layout real character. The natural Kentucky hill country terrain produces the kind of grade variety that flat farmland tracks cannot match, and South Fork's commitment to working with the natural contours rather than bulldozing them flat reflects the broader operating identity.

The bike-only policy keeps quads off the property. The restriction is the property's identity statement and produces consistent surface conditions for motocross use. Cross-vehicle facilities tend to have more surface variability and different operating cultures. The bike-only structure keeps South Fork focused on motocross specifically.

The Carnes family ownership is what shapes the operating culture. Long-running racing families bring the kind of personal investment in surface quality and rider experience that distinguishes serious operators from corporate facilities, and the multi-generational family commitment is part of what produces the reputation for some of the best dirt in Kentucky.

The Leitchfield location is in Grayson County, central Kentucky. Louisville is about an hour and 15 minutes northeast, Bowling Green is roughly an hour south, and Owensboro is about 90 minutes northwest. The position pulls riders from across central Kentucky and from the broader Louisville and southern Indiana markets.

For central Kentucky motocross riders, having a family-owned facility with the reputation for some of the best dirt in the state is a real asset. The bike-only policy, the elevated start, and the mixed loam-and-red-sand soil produce a regional Kentucky property that delivers serious motocross practice in a part of the country where similar infrastructure is uncommon.
