Track DNA — what the dirt is really like

Intermediate

Hard-packLoamSand

▸Loam — the good stuff. Takes ruts, holds a line, and rewards smooth riding. This is the surface most tires and stock suspension are happiest on.
▸Sheds water at a normal pace — usually good 2–3 days after rain.
▸High silt (74%) — this dirt turns to DUST when dry. Expect water trucks, hazy late motos, and pack extra air-filter prep.
▸Rolling ground — natural elevation worked into the layout, so the track flows instead of feeling like a flat field with jumps.
▸Wettest months: Mar, Apr, May — highest mud/cancellation risk. Prime window: Jun, Sep, Oct.

What do these terms mean? ▾

Sand / Silt / Clay %:: What the topsoil is made of. More sand = looser and faster-draining. More clay = harder, slicker when wet. Silt is the fine dust-maker in between.
Loam:: A balanced sand/silt/clay mix — the tacky, rut-forming dirt riders love.
Blue-groove:: When dry hard-pack gets polished by tires into a shiny dark racing line — grippy for some tires, ice for others.
Drainage class:: USDA’s rating of how fast this ground sheds water — it predicts how soon after rain the track is rideable.
Soil series:: The official USDA name for this exact soil type (like a breed name for dirt).
Relief:: How much the ground rises and falls within the track’s ~1 km square — flat, rolling, or genuinely hilly.
