Model Maintenance Schedule
Honda CRF125F Maintenance Schedule
The Honda CRF125F is a 125cc 4-stroke trail bike for younger and smaller riders. Honda's 2026 owner's manual sets its maintenance schedule in miles and months rather than hours, and this page lists it as printed.
Key Intervals At A Glance
- Oil: Engine oil: Replace, every 600 mi (1,000 km) / 6 months.
- Air filter: Air cleaner: Clean, every 600 mi (1,000 km) / 6 months.
- Valve clearance: Valve clearance: Inspect, every 600 mi (1,000 km) / 6 months.
How The Honda Schedule Works
Honda's trail bike manuals are written for recreational riding and use miles and months, not hours: an initial service at 100 miles or 1 month, then regular service at 600 mile or 6 month steps, whichever comes first. The only hour-based item is the spark arrester.
If you track hours rather than miles, MotoMind lets each bike follow miles or hours, so you can enter these intervals as printed.

The manual is the authority. Check the edition for your exact model year before ordering parts, and shorten intervals for competition, mud, sand, heat or heavy loads, as Honda says severe use such as competition needs more frequent service.

Ownership Notes
Trail bikes like the CRF125F are often ridden by kids and passed between family members, so the schedule is easy to lose track of. Write down the odometer reading or ride count at each service, or let an app keep it.
The manual recommends SAE 10W-30 JASO MA oil, 0.85 L after draining.
