WR 250 F WR 250 R WR 250 X
The Yamaha WR 250 series of enduro motorcycles first appeared in 2001, offering the market the Yamaha WR250F hard enduro model, built on the basis of the Yamaha YZ250F motocross motorcycle. At that time, it was an excellent 4-stroke sports machine that incorporated all the advanced technologies of Yamaha - fully adjustable off-road suspension, inverted front fork, 5 titanium valves per cylinder.
The main differences between the Yamaha WR250F and the Yamaha YZ250F include different engine settings (less forced, with improved traction at low speeds), softer suspensions, larger cooling radiators, a different exhaust (less noisy, more environmentally friendly), wider gearbox ratios (in cross-country YZ250F - close rows), the presence of lighting equipment and a side step.
However, in times of crisis, the market needed more budget solutions, so in 2008 new modifications of WR-series motorcycles were released: Yamaha WR250R and Yamaha WR250X.
Bike features
Here are the main features of these three modifications as a whole:
- common cross ancestor – YZ 250;
- excellent design;
- ease of landing.
Each motorcycle differs in many ways from its other two brothers, but there are many similarities between them, and it’s not for nothing that these are modifications and not separate models. For someone who wants to ride off-road, but still doesn’t know how to ride in general, it may be relevant to first purchase a motard, then a light enduro, and then a hard enduro. Due to the similarity of motorcycles, it will be more convenient to change from one to another than to a completely different model.
Engine
Until 2014, all modifications had the same engine, which had four strokes and one cylinder. The volume of this unit reached 249 cm³. However, since 2014, hard enduro has a new engine with fewer valves, as well as an injector. The limiting characteristics are as follows: all three motorcycles produce a torque of 23 Nm, but the light enduro and motard will have a maximum power of 31 hp, and the hard enduro – 41 hp. The peak speed for all modifications is 150 km/h.
Dimensions and weight
The hard enduro has a dry weight of 102kg, while the other two bikes weigh 128kg. The gas tank volume is the same for all and is 7.6 liters, which is enough, since the average consumption per hundred kilometers ranges from 4-5 liters. In terms of overall dimensions, these motorcycles are very similar and are considered average for their classes.
2021 YAMAHA WR450F
The 2022 WR450F is designed to handle a wide variety of conditions. New 449cc liquid-cooled four-stroke engine with electric start. The powerplant's rear exhaust intake features a higher compression piston with low friction rings attached to a longer connecting rod. The five-speed wide-ratio transmission has been improved to provide smoother gear changes, and a more efficient crankcase ventilation system has been adopted to reduce pumping losses. Overall, the lighter, more compact engine delivers increased power throughout the rev range, resulting in stronger, more linear pulling power.
The latest evolution of Yamaha's lightweight aluminum double-beam frame has been redesigned with new wall thickness and flex characteristics that provide improved cornering performance, traction and bump response to give riders more confidence to push harder in all conditions off-road. Other chassis components, such as the engine mounts, upper triple clamp and front axle, as well as the class-leading KYB® suspension with improved compression and rebound characteristics, have been carefully refined to reduce weight while improving handling and performance. To stop the new package, the 2022 WR450F features a new front brake caliper, brake pads and front disc. The combined changes provide increased power output with more controlled, linear acceleration and lighter handling characteristics.
To further demonstrate the WR450F's off-road prowess, a more compact electric starting system, improved fuel injection, a redesigned, more compact full-featured enduro meter with a higher-contrast LCD display, a new real-time fuel meter with low fuel warning, a lightweight, aluminum side stand , O-ring chain and 18-inch rear wheel come standard. The intake and rear exhaust provide the widest range of reliable power while balancing weight for excellent mass centralization.
The 2021 WR450F will go on sale at Yamaha dealers in September as part of the new generation Team Yamaha Blue with a suggested retail price of $9,799.
Chassis and brakes
The frame of the WR 250 is made of aluminum, which allows all modifications to be quite lightweight. All three have spoked wheels and a convenient, efficient steering mechanism. The exterior overall looks great.
A monoshock absorber is used as the rear suspension, and an inverted fork is used in this role at the front. All modifications have one disc at the rear and front. However, the hard enduro has a 245mm rear disc accompanied by a two-piston caliper, while the other two bikes have a 230mm disc accompanied by a single-piston caliper. At the front, the motard has a disc with a diameter of 298 mm, supported by a two-piston caliper; other modifications have a 250 mm disc, and the caliper is also two-piston.

History of changes
Here's how the WR 250 traveled during its career:
- 2001 – start of production of hard enduro;
- 2006 – digital instrument panel appears;
- 2007 – new aluminum frame;
- 2008 – appearance of light enduro and motard;
- 2010 – bikes, except hard enduro, get an inverted fork;
