Track DNA — what the dirt is really like
Intermediate- ▸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.
- ▸Holds water — plan on 3+ dry days after a real rain before it’s worth the haul. Check the track’s page/Facebook first.
- ▸High silt (69%) — 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: Apr, May, Jul — highest mud/cancellation risk. Prime window: Aug, 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.
