Backed by Real Service Manuals

This guide is based on research from approximately 100 service manuals across major dirt bike manufacturers, categorized by machine type and engine configuration (2-stroke and 4-stroke). While we recommend always checking your specific service manual for exact specifications, these schedules represent real-world best practices that work for everyday riders.

Every Ride: The 5-Minute Routine

This isn't about being obsessive. It's about catching small problems before they strand you 20 miles from the truck.

Engine Oil: The Most Critical Service

Dirt bike engines work harder than almost anything else with wheels. Proper oil maintenance is non-negotiable.

Air Filter: Your Engine's Lifeline

A dirty air filter robs power and risks engine damage. Clean it regularly.

Chain and Sprockets

The chain is your connection to the ground. Keep it clean, lubed, and properly tensioned.

Chain Maintenance

  • Check tension: 35-45mm slack
  • Clean with kerosene or chain cleaner
  • Lube with quality chain lube
  • Inspect for tight spots and kinks

Sprocket Inspection

  • Check for hooked or worn teeth
  • Replace front and rear together
  • Typical life: 60-100+ hours
  • Hard riding wears faster

Adjustment

  • Loosen axle nut first
  • Adjust both sides equally
  • Check alignment with straightedge
  • Torque axle to spec

Suspension: Keeping You Connected

Suspension takes a beating on the trail. Regular service prevents expensive failures.

Engine: Top-End and Valves

The engine is the heart of your bike. Know when to service it.

Track Top-End Hours

Know exactly when your top-end was last done. Log piston changes, valve checks, and rebuilds.
