It’s an off street enduro bike, constructed for driving within the grime, reminiscent of single-track trails, the desert, or mountain trails. It additionally has a headlight and tail gentle. Nonetheless, the WR250F will not be a avenue authorized grime bike as a result of it’s registered for off-road use solely by the manufacturing unit.

What’s the distinction between WR250F and WR250R?

The principle distinction is that the WR250F is a high-performance path bike for off-road solely driving, whereas the WR250R is a street-legal grime bike for dual-sport and journey driving. Whereas they’re each 250cc 4 stroke grime bikes, they don’t share any of the identical elements. 

Who’s the Yamaha WR250F for?

This can be a good bike if you need a light-weight obligation enduro bike or excessive efficiency 4-stroke path bike

What do I imply extra particularly? In case you’ve already discovered the primary strategies to driving off-road and have constructed up your confidence from driving a newbie bike, reminiscent of the TTR230, then the WR250F is an efficient improve. 
It’s taller than newbie bikes, however is an efficient dimension for older teenagers and adults in case you are 5’8″ or taller. 

Engine – what to anticipate

The 250cc liquid-cooled 4 stroke engine is primarily based off of the YZ250F MX bike, however it’s tuned higher for path driving. It has higher low-end torque and a smoother energy curve due to the completely different cams, gas tune, and exhaust. This makes it simpler to experience within the woods as a result of it’s extra predictable and controllable. 

The WR250F doesn’t get the identical updates because the YZ till at the very least a 12 months later as a result of it’s not the premier 250 mannequin from Yamaha. Since 2001, it’s gotten a number of main adjustments that embrace utterly completely different frames, engines, exhaust, and fueling techniques.

The 2014 and older 5-valve engine w/ a carb


The primary technology WR250F, which is from 2001-2014, has about 30 horsepower in inventory kind. You’ll be able to improve that with some easy mods, reminiscent of consumption and exhaust uncorking.

2015+ WR250F has about 35 horsepower in inventory kind. The rise in energy is from the brand new reverse-style engine taken from the YZ250F. It’s been barely detuned to have smoother and broader energy for path driving, however it nonetheless has that race bike “snap” while you twist the throttle at excessive RPM.

Is it highly effective sufficient?

How a lot energy do you really want? Most riders can’t take full benefit of a WR250F with 35 horsepower whereas path driving. 

So, even when you weigh over 200 lbs, it has loads of energy to do most any form of driving. With that mentioned, the 250 four-stroke lacks low-end torque proper off idle. If it’s essential lug it and brief shift, then you may want a 350 or 450

Does it have gas injection?

The WR250F had a carbureted engine from 2001 till 2015 when Yamaha modified to the YZ-style reverse engine with EFI. 

This was a giant change in efficiency, in addition to with the ability to experience at completely different elevations without having to alter jets – the gas injection auto tunes for air temp and elevation (not exhaust or engine mods although). 

Updating to a 6-speed transmission over the 5-speed within the 2014 and older fashions helps if you need that additional gear for top velocity driving. 

Prime velocity

You’ll be able to attain a high velocity of about 80 mph on a inventory WR250F, however why do it’s essential go that quick? In case you’re desert racing or drag racing, the max velocity is necessary, in any other case it’s ineffective for path driving – you may all the time make it quicker with one low-cost half.

Need to have a better high velocity? Simply change the rear sprocket with one that’s smaller/has much less tooth. Or, if you need a decrease first gear for onerous enduro driving and higher acceleration, a much bigger rear sprocket will immediately assist.

Can it cruise on the freeway?

Initially, a WR250F will not be avenue authorized until you get it registered and plated, so you may’t legally experience on the freeway. With that mentioned, possibly you probably did convert it to be avenue authorized otherwise you need to cruise on gravel/fireplace roads to make it again to camp faster. 

Nicely, a inventory WR 250F gained’t be very comfy driving on the freeway at 60-70 mph since you’ll need to hold the engine revved at a excessive RPM. You’ll be able to change the gearing to cruise at these speeds extra comfortably, however you’ll need to sacrifice a taller first gear and slower acceleration total.


Whereas the WR250F could also be primarily based on the 250F MX bike, the suspension is far softer, particularly on excessive velocity hits, reminiscent of rocks, roots and path chop. 

It acquired up to date in 2003 from its unique as a result of it was a bit of too plush for aggressive path driving. No main adjustments till 2015 when Yamaha modified the spring charges and valving for a greater performing however plush experience.

Entrance forks

Whenever you go from a cheap path bike, such because the TTR230, and improve to a WR250F enduro bike, one of many huge enhancements is the entrance forks and rear shock. You get a totally adjustable set of forks which you could tune to your weight, however there are easy steps to make the inventory suspension work very properly for you.

Yamaha has slowly made the WR250F forks stiffer through the years to compensate for how briskly the bike is, however it’s nonetheless made to have plush suspension in comparison with the cross-country enduro bikes and particularly the motocross bikes. The burden vary is 160-180 lbs, however relying in your velocity and sort of driving, that vary is a bit of larger.

In case you’re heavier or lighter, you’ll need to change the fork springs so you will get the correct sag and forestall fork bottoming. Then, you can begin adjusting the compression and rebound clickers. These modify the velocity of damping, basically providing you with a “stiffer” or “softer” feeling. Tuning these could make you’re feeling extra comfy and experience quicker.

Rear shock

The inventory rear shock is properly balanced with the forks, however you additionally must have the fitting shock spring fee to match the entrance forks in your weight. Then, it’s essential get the shock sag adjusted so that you can get the correct experience peak – when your suspension isn’t balanced, you’re lacking out on a greater dealing with grime bike that offers you extra confidence and management.

Then you will have the rebound damping clicker, in addition to the excessive velocity and low velocity clicker changes. By studying how your suspension works and spending time tuning it, you will get your inventory WR250F to work nice on the paths with out spending hundreds of {dollars} at a suspension tuner.

Dealing with

In case you’re coming from an older type path bike, the WR250F goes to deal with a bit of bit in another way. Because the chassis is much like the motocross bike, it’s longer and due to this fact might be extra steady at larger speeds and on rougher terrain. 

On the flip aspect, tight turns might be tougher as a result of the steering is slower. Can it deal with tight, single-track trails? Sure, however it’s one of the best grime bike for woods driving, though it’s gotten higher total because it first got here out. 

Weight comparability

Relying on which 12 months you get, the Yamaha WR250F weighs about 250-255 kilos, which is common in its class. In comparison with a 250 newbie path bike, it’s barely lighter as a result of the elements are larger high quality supplies with extra analysis and improvement put into it.

With that mentioned, although it’s heavier than a TTR230 path bike, it may well really feel heavier as a result of it’s taller and larger in bodily dimension. The next middle of gravity makes a giant distinction in dealing with, and that’s why I all the time suggest beginning on a shorter grime bike until you’re an abnormally tall rider.

Dimension Dimensions

It’s one of many tallest grime bikes obtainable from Yamaha, and that’s due to the full-size wheels, suspension journey, and chassis dimension. Brief riders, like me, are inclined to complain in regards to the peak of recent grime bikes, and for good motive. 

Tall grime bikes are tougher for us to deal with as a result of we will’t simply contact the bottom. However, the rationale they’re so tall is that they’ve extra suspension journey and also you want sufficient floor clearance under the body so that you don’t get it caught driving over obstacles. 

With a 58″ wheelbase, which is so long as it will get for a dust bike, that is one more reason why it’s so steady however steers slowly at low velocity.

Seat peak – what dimension rider is the WR250F for?

The inventory seat peak of a WR250F is 37.6 inches, which is fairly typical for an enduro grime bike. What does that imply for you? Nicely, when you’re brief like me (5’6”), then it’s going to really feel actually tall.

Ideally, the WR 250F will fit your needs properly when you’re 5’9”-6’2” tall, however it additionally is determined by your inseam size. With that mentioned, seat peak and your bodily peak aren’t the one components to think about. In case you’re a newbie, choosing the proper grime bike is extra necessary as a result of you should have extra confidence when you can contact the bottom with one foot.

However, as you enhance your stability method, you gained’t want to the touch the bottom or drag your toes whereas driving as a result of you will have extra management and confidence together with your bike.

Reliability – how lengthy will it final?

The reply everybody needs to listen to: “air relies upon.” On one hand, the WR250F is an especially dependable grime bike while you correctly preserve it, reminiscent of checking the oil and protecting the air filter clear. 

It may well final a whole lot of hours and a few years earlier than needing a rebuild, particularly when you’re not bouncing off the rev limiter on a regular basis. The older 5-valve 250F engine was most likely essentially the most dependable engine you could possibly purchase, and the brand new reverse engine is nearly as sturdy. 

On the flip aspect, when you don’t examine the oil, don’t ever clear the air filter, and always hit the rev limiter as a result of it sounds cool, you may be rebuilding your WR engine in lower than 20 hours.
