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 bikes.

So this applies to the following motorcycles: 2008 Yamaha WR250R, 2009 Yamaha WR250R, 2010 Yamaha WR250R, 2011 Yamaha WR250R, 2012, Yamaha WR250R, 2013 Yamaha WR250R, 2014 Yamaha WR250R, 2015 Yamaha WR250R, 2016 Yamaha WR250R, 2017 Yamaha WR250R, 2018 Yamaha WR250R, 2019 Yamaha WR250R, 2020 Yamaha WR250R, 2021 Yamaha WR250R and who knows how many 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.

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.

Consumables needed for WR250R

You will also need the following generic consumables that you can use for any motorcycle.

ProductThumbnailDescription
Chain lubricantmotorcycle maintenance tools - motul chain pasteThe chain needs to be lubricated every 800 km/500 miles (or more, if it gets wet/dirty), with variations recommended between manufacturers. Motul chain paste is cheap and well-loved.
Chain cleaner brushmotorcycle maintenance - chain cleanerA chain cleaner brush makes cleaning off grime and then distributing new lubricant much more easy.
Paddock standmotorcycle maintenance tools - paddock standLubricating the chain and changing the oil both become a lot easier once you use an affordable paddock stand (not necessary if you have a center stand).
Cable lubricantmotorcycle maintenance - cable lubricantRemember to lubricate your clutch cable (and brake cables if you have them) with a cable lubricant. Protect All Cable Life is a good general-purpose lubricant.
GreaseGet a good lithium soap based grease for lubricating major components like your side stand, centre stand, and bearings.
General motorcycle consumables — Brake fluid, chain lube, clutch lube, and grease

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.
