Yamaha YZ125X - Long Term Review 

Great bike….bought one for my 14 year old son but find myself enjoying it more than I would have ever imagined. I’m 190 lbs and it has no trouble hauling me around….only drawback is in the more open spaces out in the desert….runs out of gears fairly quickly. We’re running the Lectron carburetor and so far very happy with it.

You convinced me to buy a 125x. I just picked up a 2023 yz125x. It is amazing. I cant believe its a 125. I weigh 225 lbs and its not a problem at all.

"It felt like a mountain bike, but had an engine" - this statement sold me already! 👍😁👍

Great review! I've had my 2022 125x since September and I couldn't be any more happy with it. I'm about 175lbs and this bike pulls me through the trails at Capitol Forest, WA with NO problems... such a blast!! Thanks for sharing!

My 2020 yz125 has 80+ hrs on original top end ... Runs as good as ever ... YMMV ...

11:54 PLEASE don't avoid those! why miss an opportunity to jump up and back into the trail?! Thank you for the great review brother.. looking into buying one o'those and after owning 1x YZ125 for 20 years, 2x FE450s and 1x GG EC250e and as a 3x Romaniacs Silver competitor, i confirm that all the info in this video are 100% accurate! 125s are the best trail bikes for fun fun fun and most underrated by all muscle boys! Add the 'X' for doubling the fun factor! Thank you Yamaha for not giving up on them!

I have not had a bike for 45 years and at 61 I want to start riding again!! And I have been looking at this bike!! And now I am sold!! Thank you!!

Great review! And it was because of you I bought a 2022 125X a couple of weeks ago. The bike really is amazing. I could start the bike with my hand, so funny how I do not even miss the electric start that my TE250 has. I will say that the Mikuni is prone to have a defective jet block gasket. Sure enough the 125 mikuni had the defective gasket. I replaced the gasket with the one form JD and rejeted the bike for my altititude, 5k-8k. I have no bog bike runs like a champ. I purchased a Keihin with the stic jet block for my 2018 TE250 because of the low speed bog I was getting. I took apart the mikuni from the TE (which is the exact same carb for the 125) and sure enough it had the deformed jet block gasket. I replaced that one as well and will be testing it on my 250 to see if it is better than the Keihin. So, for those thinking of getting this 125 with the mikuni. I would first replace the jet block gasket and purchase the JD Jet kit. All in for less than $100. This may be all that is needed. Thanks Rado for convincing me to make the move. Was always skeptical about 125's, but not any more. Hell I might sell the 250 and get another 125. LOL

Just bought this bike for my 13yr old son. It’s a bit big for him now but will be a great bike that will last him for years of fun.

Thanks for your thoughts and showing the riding. Most fun in your life is the best compliment. 💪🔥

Watch out KTM!!! Nice to see a Japanese company back in the 2-stroke game, need the rest of em to join the party

Always love the reviews mate! every one loves a screamer, makes you feel like a hero!! LOVE IT!!

Nice bike. I used to race B class with a RM 125s many,many years ago in the 70s and 80s. I hate snow. Ride safe my 2 wheel friends.

I would say the most economic thing would be to try keeping the Mikuni and add some needles from Suzuki RM125, pair with correct pilot jet and finally check the float height as the Mikunis sometimes come with a too low height (too much fuel into the bowl). On the Italian Husqvarna 125 the Mikuni worked great with the above mods. Stock the Mikuni makes the bike being boggy/flat in the mid range. 125 is the way to go.

Good Review on Yamaha 125x . Looks like 2022 is something to look for on 125x thank you for this review

Watching this I’m thinking like wow you almost never have to use the clutch on this bike, then I think about how much I use my clutch on my 450 to take away power … I’m thinking I should get this bike .. found a 2021 yz125x for 5500 🤔… I’m 39 and mostly a vet track rider, I hit the hills too so I’m thinking of getting one of these… and I was sold when you said “ mountain bike with engine “

Thanks a lot I was hoping that this would be a video that would convince me that it it’s the bike I need. But now I’m drooling even more 😅

Keep your quality content coming. I know this has no relevancy to today's video. I just wanted to during this holiday season lift up the spirits of the Smith family. Al Smith Sr and Marty Smith we're both stand up men in our community. After 22 years plus I am finally moving from the original Smith family home here in point Loma, built in 1923. Before the iron horse I can picture Al's father on horse back going burr burr right here next to the slew in the San Diego River. Again Happy holidays to you and yours 🐎🏍️🇺🇸

I’m saving to buy a new yz 125 x right after Christmas and I can’t wait after watching these videos I’m 15

I have a 2020 125x and it’s the best bike I’ve ever ridden. Take it over my 450r any day.

My favorite bike of all time! You feel like Superman

The powerband reminds me of the Yamaha IT200 clean off the pipe, but I'm sure YZ pulls harder when it is on the pipe. I was never let down by that bike. In a race different story. Thanks for the review. Sounds like a fun bike.

I wonder how the jd jetting kit for the mikuni feels vs the keihin with the jd kit.

Ordered a 2022, can’t wait to try it

I liked the review. But how to ride a 2022 2 stroke in California without a green-sticker on public land? I would love a YZ125x, but I don't think it will be possible to ride a new 125x on California public trails anymore. I hope a green-sticker version will come in 2023.

should i get a yz125x im 13 5"8 150 pounds currently

So which bike is going to replace My KDX 200 the 125X or the 250X?

What’s up Rado? Thanks for the great videos. I purchased my son a 2020 yz125x based off of your reviews. I’m having trouble getting it to idle a little higher. It seems as if the idle screw is stuck. Is it really worth the $400 for the JD Keihin carburetor with the JD needles already installed? I can probably get this screw out and replace it with an aftermarket idle adjustment screw. Thanks for your help.

Great video and review. I want to buy one lol. Subbed 🙂❤️🙌

So much blast

If youre running good oil/gas mix and good tranny oil, how many hours on the crank and bottom end could one get? Roughly. Thx

i am also thinking about getting a yz 125 for the track, i am just 60kg so it would be great to have a light bike 🙂

The 125s are awesome I got the chance try one the other day very capable machines I liked it.

How would this bike compare Honda Crf250f? Obviously 2 stroke vs 4. But for woods, trails, enduro wchich one would be be a better option? Not going to be racing.

Back in the day I just went ftom a 50 to 54 sprocket on the back..

They have a brand new 23 yz125x at the dealer. I want it… old lady isnt too happy about it tho. I want a 250. I cant make up my mind on 125 or 250

Good video. I agree with everything you said about the 125

Have you ridden these trails before? It looks like your in slow motion!

well said bro, awesome vid

I agree in my racing time with husky I found i learnt more from my 125 wr than any cc I raced. Just wondering u ever though of running a smart carb because of altitude differences you ride.

So you did the carb jettings? What about the stock one is it still ripping?

Hey rado you should give a 2021 ktm 125xc a try the yz 125 and 125x are very nice 👍 thanks for the review

How does it do on steep hill climbs?

How with Front Up Side Down..? Like WP KTM EXC or Not..?

So you didn't try the stic in it?

Great Video! Is the vibration manageable? I know your on the KTM’s a lot, how much of a difference is there really?

Building a 2002 YZ125 right now!

Your suggestion on a 2022 yz with all new platform or a 125 x whatever year if you had a choice for mainly woods riding I’m a b vet rider

Howmuch dat bike sir

What work you did on the YZ 125x…like gearing and carburation? Would you mind letting us know. Thanks

Man i love this Bike!!!!!

Hey nice review. I have a 2022. Was that kiehen a 36mm short body? Thanks

But what do you think about the husaberg te250 ?

Seems if one is 200 pounds or more full of muscle this bike isn’t big enough??? Anyone 6-3, 200lbs plus own one?

I wish I had like this bike too🥺😐 Nice🔥💪💙 From PH🇵🇭

Can you please do a Lectron comparison and also Apex head review for the 125x?

how was the vibration ?

Is the 125x a 6 speed.

the best bike i had...

How does it compare to the KTM 125 XC? Does it easily stall when going very slow single track especially in 1-2 gears? Who cares about mx track. It's an X but you keep talking about the track. If you're mostly a track guy, why get the X?

Man, had no idea they came with mikuni’s

Yz125 or yz250 for 180lb rider

Would this be tall enough for A 5’1 person

125x vs 250x for 215lb rider?

It's fun bc it's a Yamaha 2 stroke & not a FU broken gutless 4 stroke.

#somuchblast!!! #merchlogo!!!

Man i just want to say yhat you are much better than cyle brotherson because he is sponsored by ktm so he cant say en ything good about yamaha

Hello whats up guys aku ingin motor itu tapi tidak punya cukup uang 🥲
