Model Maintenance Schedule
KTM 300 XC-W Maintenance Schedule
The KTM 300 XC-W is a 2-stroke enduro bike with oil injection. Its 2026 owner's manual runs on longer intervals than KTM's motocross 2-strokes, and this page lists them in engine hours.
Key Intervals At A Glance
- Oil: Change the gear oil, every 45 hours or every 24 months.
- Air filter: Clean the air filter and air filter box, every 15 hours or every 24 months.
- Top end: Perform minor engine service (change the piston; check the cylinder head; change the O-rings of the manifold and the cylinder head), every 45 hours.
- Fork: Carry out fork service. (All except HARDENDURO models), every 45 hours.
How The KTM Schedule Works
The KTM owner's manual lays out service in five columns: after one operating hour, every 15 operating hours, every 45 operating hours, every 90 operating hours and every 24 months. An open circle in the table marks a one-time job and a filled circle marks a repeating one. The manual also warns that harsh conditions such as heavy rain, mud, sand, snow, extreme temperatures or frequent full load can call for shorter intervals, and that intervals can differ by country.
For this model, the gear oil is changed every 45 hours or every 24 months; the minor engine service, which includes a new piston, is every 45 hours; the major engine service, which covers the bottom end, is every 90 hours. Everything else hangs off those service levels.

Ownership Notes
Because the XC-W is an enduro model, the 2026 manual sets gear oil, the minor engine service and the suspension service on the 45-hour line and the major engine service at 90 hours, which is a much longer leash than the SX race bikes. The oil-injection system adds its own items: the oil pump and the screen in the oil tank are on the 90-hour line.
The manual covers the 250 XC-W, 300 EXC, 300 EXC Hardenduro, 300 EXC Six Days, 300 XC-W and 300 XC-W Hardenduro. Hard enduro riding with lots of clutch slip and low-speed heat is exactly the harsh use the manual warns may need shorter intervals.
