Know Before You Go

Open practice days
Most MX parks run open practice on weekends for $25-50. Sign in at the gate, sign a waiver, and ride your allotted moto groups (typically 30 min on, 30 off).
Required gear
Helmet (DOT or Snell M-rated), goggles, gloves, chest protector, knee/shin guards, boots, and a full-sleeve jersey. Most tracks won't let you ride without all of it.
Class structure
Tracks separate riders by bike size (50cc / 65cc / 85cc / 250cc / 450cc) and by skill (beginner / novice / intermediate / pro). Sessions rotate through the day.
Track conditions
Tracks get watered before sessions and groomed between motos. Soft loam in the morning hardens into ruts by afternoon — adjust suspension and tire pressure.
