Chart notes
- 1. Items marked with an asterisk in the manual should be performed by a Yamaha dealer - they need special tools, data and technical skills.
- 2. Calendar items (coolant, brake fluid, fuel hose) sit in the Remarks column rather than in the interval columns.
- 3. The WR250F is street-legal in some markets, so the manual prints two charts: an emission-control schedule keyed on odometer and months, and a competition schedule keyed on races. Both are here as separate tables. Use the one that matches how the bike is ridden.
From the manual
- Service life of parts varies significantly with the environment the machine runs in (rain, dirt); inspect earlier if conditions are harsh.
- Periodic inspection is essential to make full use of machine performance.
