Yamaha WR250R Maintenance Schedule and Service Intervals

2019 Yamaha WR250R

This is the maintenance schedule and associated service intervals for the Yamaha WR250R.

The WR250R has been fundamentally unchanged since it was first introduced in 2008. It also has relatively little in common with its similarly named cousin the Yamaha WR250F, apart from the fact that they’re both 250cc four-stroke dual-sport motorcycles.

So this maintenance schedule applies to the Yamaha YR250R from 2018 through 2021, and who knows how many years more.

The WR250R is the version that’s meant to be able to be registered for the road. It’s pretty powerful for a 250cc single-cylinder bike, with a 30hp/23kW engine. It’s still learner-legal, though, in places like Europe, Australia, and New Zealand that have learner legal schemes.

By the way, yes, there have been updates to the WR250R along the way — a few more reliable components like fuel pumps, and revised designs. But nothing affects the spare parts or the maintenance schedule.

What you need to service the Yamaha WR250R

To service the WR250R you need the following parts and consumables, per the manual.

OilYamaha recommends Yamalube 10W-40 or Yamalube 10w-50. It’s affordable and high quality.

Yamaha WR250R Maintenance Schedule

Below is the maintenance schedule for the Yamaha WR250R. It’s slightly modified to fit a web page format, and simplified slightly (combining two parts that were split apart).


  • Mileage comes from the US manuals, kilometrage from the European/Australian ones. Astute math buffs will notice they don’t quite add up (the Km intervals are usually wider
  • At the end of the maintenance schedule, follow in the pattern observed
  • Yamaha recommends you only grease external parts, lube the chain, and change the oil, and take everything else to the dealer
  • Air filter: The air filter needs more frequent service if you are riding in unusually wet or dusty areas.
  • Hydraulic brakes:
    • After disassembling the brake master cylinder and calipers, always change the fluid.
    • Regularly check the brake fluid levels and fill the reservoirs as required
    • Every two years replace the internal components of the brake master cylinder and caliper, and change the brake fluid
    • Replace the brake hose every four years, or if cracked or damaged.

Maintenance schedule for the Yamaha WR250R

About the Yamaha WR250R

The Yamaha WR250R is the more street-capable version of the WR250F, with linear power delivery that works well on any surface.

The engine is a 250cc water-cooled thumper that churns out 28 ponies and 17 foot-pounds of grunt, but you have to wind it out to a screaming 10 grand to get all of it.

The good news is that the engine likes to be wound up, so you can go ahead and wring the throttle with abandon. Part of this power comes from the Yamaha Fuel Injection (YFI) system and ECU-controlled, coil-on-plug ignition system.

The factory also uses something it calls the “EXUP Exhaust” valve and electronic intake-control valve to stretch the usable powerband a bit, and the results are encouraging. Between the engine performance, the six-speed transmission gearing and final-drive ratio, the WR250R can prowl around rocks and rough terrain with almost trials-bike control and resistance to stalling.

The mill delivers its power while sipping at the gas at an impressive 71 mpg, and if you have the nerve for it, a top speed somewhere just shy of 90 mph. That’s on the superslab of course, not off-road.
