Dirt Bike Service Due Calculator

How The Calculator Works

Each model uses the hour-based tasks from the maintenance schedule in its owner's manual, the same data on our model maintenance schedule pages. For every task the calculator works out when it is next due:

• If you leave "last full service" blank, it assumes every job was done on time since the bike was new, so the next due point is the next multiple of the interval. At 37.5 hours, a 15-hour oil change is next due at 45 hours.
• If you enter the hours at your last full service, it adds each interval to that number. If the bike was serviced at 30 hours and now reads 50, a 15-hour job was due at 45 and shows as overdue.

Tasks show as overdue, due now, or coming up when they are within 20% of their interval. That 20% window is our display setting, not a manufacturer rule. One-time break-in services, such as KTM's first oil change after one operating hour, are noted but not repeated.

Models Covered

We only include bikes whose manuals we have read and published. Honda's CRF250F and CRF125F trail bikes are left out because Honda schedules them in miles and months, not hours; see their pages for those intervals.

Limits Of Any Calculator

Each schedule assumes the use its manual was written for. Motocross race manuals, such as KTM's SX models and Honda's CRF-R, assume racing, while KTM's XC-W and EXC enduro manuals print their own schedule with longer intervals for some jobs, such as the two-stroke piston at 45 hours instead of 15 (KTM 2026 300 XC-W and 250 SX manuals). Pick the model you actually own. KTM's manuals say harsh conditions such as heavy rain, mud, sand, extreme temperatures or frequent full load can require shorter intervals, and Yamaha and Honda base their race bike schedules on races, not calendar time. Calendar items, such as KTM's every-24-months jobs and yearly brake fluid changes, are not covered here because the calculator only knows your hours.

The calculator also cannot see your bike. If the clutch slips, the bike starts hard, or the oil looks wrong, inspect it now instead of waiting for the number.

Track It Automatically

MotoMind keeps this running for every bike in your garage. Set each task to your manual's interval, update hours from your hour meter or the GPS ride tracker, and every task shows as upcoming, due now or overdue. Date-based tasks such as brake fluid or coolant also get push reminders. Hour-based tasks show their status in the app but do not send a push notification, so open the app after each ride.
