Yamaha YZ250FX 100% STOCK - Does it stall a lot?? 

I wish Yamaha would make a 350fx with a longer stroke for better bottom end torque.

250FX is such an underrated bike.

I believe these 250fxs are the best lugging 4 stroke

I find that my YZ250fx will lug very well. Where it has issues is if I chop the throttle and then get back on the gas quickly, like when I need to lift the front end for a log. That’s when it stalls or flames out unexpectedly.

I own a 2019 300rr Beta and 2020 yz250fx.....for the slow stuff, the Beta is the far more competent bike for sure, awesome bike....but the bike that makes me super excited to ride is my yz250fx, what a blast it is, the engine's power curve, the sound, the suspension....the riding experience is just the best with this bike especially in the medium to quick stuff.....not a bike for hard enduro or the very slow stuff, engine has too much compression and too reactive of a bike to ride in those conditions but for everything else, its unmatched!

Very interesting ! I found a few (very few) comments on the topic in forums. But this 'no shifting' test going up a hill is a very smart . I'm looking at getting one. Thanks!

Good review. But the comments are respectful and I appreciate that. Rare to see mature comments.

Great video man. I’m genuinely impressed. It was super low in the rpm several times and kept going. I had a crf450x that flamed out constantly. I switched to a xcw tpi. That Yamaha did well. I imagine a WR would be even better. I’d watch that video

Those are exactly the kind of trails I rode for over 40 years and that is the bike I could have used......a lot of times when you're really excited about getting up the trail, you get a little sloppy and don't get your shifts quite right. When you have a bike that will lug without stalling out, it makes your day so much more fun and allows a fella to get away with less than perfect riding skills every minute. When you're done with that bike send it my way! It might make an old guy look a bit younger again!! Hang in there, Rado! Thanks for the look back down the trail; it sure gives a feel of how steep/technical it was.....good job. Keep the Faith, Tom P.S. A fella would like a 300 for that kind of hills, maybe........or it may "feel" heavier(even if it wasn't) due to bigger piston swinging around. It is almost impossible to get the bike too light when you're an old geezer like me.

Rado...you have amazing content...I like that you mention what gear you are in...when you shift...clutch or no-clutch...really gives us a good perspective into what the bikes can do. Thanks!

With the 2020 YZ250FX there is also a Tech Bulletin number M2020-006 this is related to starting issues, stalling, and hard starting when Hot. The dealer will re-flash the ECU with new parameters that the "App" doesn't have access to. This is a good one to have done.

I have a 19 250fx, never stalls with proper clutch use, I was extremely tired today after doing around 27 mean of tight single track and stalled it a couple times but it was me not the bike, I lug around in second gear most of the time on these trails and it does not stall, greatest bike in my opinion, wouldn't have anything else

Thanks mate. Good honest and real unbiased content we can trust👍👍

Awesome video! I love how you explain what gear you are in AND if you are clutching or not. What MAP were you running? Wild or mild?

I've had my 20 250fx since august and its yet to stall on me. If I know I'm going to be doing some slow, tight crawling sections I just flip into mild power mode and for me it seems to be able to handle very slow speeds without stalling. Super impressed with this bike, I love it.

I'm used to a 250 4 stroke(283cc with the big bore kit).. We have very little "fast terrain" but I still get the bike around pretty good. It is a little unpredictable though, at times I can't believe how well the engine lugs and then there's those moments when it'll flame out and I almost have know idea why 😐

I have a 2019 yz450fx and read alot of things about it flaming out or not wanting to start in gear wich I have had no problems with whatsoever. Starts in gear almost everytime flawlessly and basically never flames out so I'm not sure what people were talking about

I don’t have that bike but looks like it will do trail and track very will watching this channel thank you for this video it was very informative 👍

Apparently, you can tune stalling out further with GYTR tuner by adding ignition and removing fuel at low RPM. Or something like that.

Great video Rado! That YZ250FX seems like a great bike. Beautiful terrain out there, I would love to ride it one day. JJ

Yeah I can vouch for Rado! That section is very steep, technical, and Rocky! Haven't been up there in a year or so. Time to go back. Great video! I'm going to have my first opportunity to ride that exact same bike this weekend. Can't wait!

Interesting ! I have a 2020 KLX 300R, and I gotta say...I'm just about ready to upgrade. Don't get me wrong, it's been great...taught me how to ride but, I want something a little more powerful, quicker, and ultimately something LIGHTER. Good lord the KLX300R is like 280 pounds.. I'm over it. Been looking at this 250FX and the KTM 350 XCF.

Those yz250 are sweet bikes 💪

I just out a Rekluse Radius CX in my bikes and dont have to worry about it.

Great video fantastic bike stay safe looking forward to next one 🇬🇧👍🏻

I don't know why but I have always stalled more on 2 strokes than 4 strokes. I don't know if that's because I can hear that point before stalling better with the four stroke and I just naturally use thee clutch.

I have this bike, did you get the bulletin done for the running rich condition? It is free and really helps the bike out. Only issue I have with this bike is the suspension is way way to stiff for slower stuff and rocky trails. It tosses you around like a rag doll

I have the 450fx and what I use in the rocks and I believe the 250fx has the same tunes available with the app is mx feeling power in map 1 and map 2 is the mild tune and that map is perfect for rocks and tech stuff. You can actually lug it a little more on that tune and its much easier to ride through those areas so try it and see how it is.

Were did you shoot this video ?

I’ve seen some movies here on RU-vid about stalling 4-strokes. I think these people just don’t have no feeling when to shift down, how to use the clutch and the gas. If you ride like a moron of course it stalls.

Good video! I'm testing a 2020 yzf250 for the woods on my RU-vid channel. I'm cheating a little bit by putting a recluse radius cx clutch in mine. Zero stalling!

Which map was the test done with.(I own one of these.)

For primarily woods riding on the east coast, would you choose 250fx or WR450 (uncorked)? I've read the 450fx can still be a bit of a handful even with a mellow map. 205lb rider (probably 215/220 with full gear), 50 years old in good shape.

The same people that whine about 4 strokes stalling have to clutch their smoker to stay on the pipe. Its simple riding technique, applied differently to different engines. And FFS rev out a lower gear in a technical situation instead of trying to clutch a gear high.

The sweet spot would be if they made a 350 or 400.

Wow nice bike! Hey where is that trail?

are these bikes lightweight?

Does the yz250fx compare to the wr250f?

How does it compare to the honda 250rx?

Did you remove the 270 kit? Or did you shoot this prior?

Same as wr 250f ?

I had to get my 2020 reflashed cause it would stall so easy. It would stall all the time. Yamaha has a bullentin on it. Beside that bike is freaking amazing. Just aggregating on how easy it was stalling but reflashed fixed that issue
