In This Week in MXA, episode 157, presented by O’Neal, Josh Mosiman, Josh Fout, Josh Holley and Shawn Bushnell test our 2024 Yamaha YZ250F, equipped with Twisted Development airbox mods and Vortex ECU mapping, head to head against a stock YZ250F. And, we rode our 2024 Yamaha YZ450F with the stock cable clutch and with the GYTR hydraulic Brembo clutch upgrade, which is available for $299.99 through Yamaha dealers. Yamaha’s Mike Ulrich and Steven Tokarski joined us for the day and helped us through the testing process, refining both of our blue machines. We also have some AHM-tuned suspension on our YZ250F and MX Tech A-kit suspension on our YZ450F.

The blind test rider said barely and just maybe
Good result but you need to be searching for actual power if you want to compete - thats what yamaha knew shifting some power up
Shawn is a fast rider who's style is to "clutch it" and stay high in the RPM's. There isn't much difference at the top rpms with those mods, so the power benefits are mostly/only noticed on the bottom end, when the clutch isn't being used. It was a massive difference.
It better be for the cost...my point stands. If you want to win races you will want more peak power. The yamaha has a perception of being fast via the star program but the production bike leaves a lot to be desired in the power department. It has had the best "delivery" of middle of the road actual power. @@Quadz10
@@HPRaceDevelopment Agreed. Those Dyno numbers don’t lie and HP up top wins at the 250 class. 💯
Jamie has to be rolling in dough at this point especially with videos like this pouring business in for those that can afford it and are looking for that extra edge
The one "small" change the title said isn't small or one... completely new airbox and a different ignition isn't a small mod...
I’m wondering if a twin air powerflow kit (screenless) and a tweak on the power tuner app could get it in the same ball park without modding and buying a vortex
weird way to say "buy a 2 stroke"
Funny how no other shootout addressed the issue with the stock bike.
You realize nearly all shoot outs are complete BS right? ALL are incentivized in one way or another
Yamaha needs to add a secondary throttle plate so they can achieve higher velocities at low rpm and still get that over-rev at the top of the RPM range.
It’s weird other magazines said it still had great bottom end and when they put the map to aggressive they said it was exciting! But again no 2 bikes are exactly the same.
Low end on these are shit
@@AA-mk4pu nope my friends is fine.
You might as well buy a 450 if that is what you are seeking.
That's for quitters! Next week we are going to deep dive into a Star Racing Yamaha Race motor and why you need it.
@driftnasty1 spending that much on a 250 is for math fails. Period. You get the same with the 450 as spending all that on a 250. Done.
@@HorsepowerHouse It was just a dry joke, I was kidding around....
@@driftnasty1 dust is not detectable online
In my humble opinion the right guy on the right bike with the right suspension and offset settings will do good .
As the infamous sgt. Schultz once said I know nothingg .
Josh, u r animal. Wtg giving the viewers awesome bike information before and after.
So you’ve got to mod the air box and the whole ecu to land in the same place as the 23 was… I’ll stick with a ktm… (written like a ktm hater in ktm comments lol) also those conditions are like an euro sandy ish track 80% of the year
Exactly 💯
Funny thing is this is the only magazine that has said they didn’t like the bottom end! Others said they loved it and when they changed the map to aggressive a couple of Honda guys said it was like a 350.. heard that numerous times. Mine is supposed to be here in a few weeks.. can’t wait
@@mxr248 not listening to any magazines but using my own mind, if you make the chain more durable it’s heavier & thicker therefore more drag & less response and change nothing else therefore the result is less bottom end power & feel maybe this is the only true magazine out there how can it feel like a 350 if it has less than the 23 it doesn’t make sense…
@@E63s_Scott absolutely wrong with your timing chain theory buddy.😂 you act like they threw in a drive chain! If you think I’m wrong go ask Mitch Payton! He said the same thing about the Yamaha! The timing chain doesn’t nor did it change the low end of the Yamaha! Designing air flow can though. Plus the fact only one magazine said anything about low end. Most everyone has said it’s still amazing. Just take the thing off of linear power map and put it to aggressive. Huge difference. It’s more of the mapping as well. Even some RUclips motocross guys that ride Honda, KTM and other brands said the Yamaha was amazing and they had no complaints whatsoever so ever. The Honda guy said he’s going blue now! So again it’s not the timing chain. Even Mosiman corrected himself after saying that stupid crap. Mitch Payton told him the same thing. The timing chain would not do that.. 🤦♂️
It is all about money, it is impossible that the YZ is the best bike on the market, air filter problems, low HP and the frame isn’t the same as old good days, that air box looks terrible and makes the bike looks ugly, and mostly importante the Yamaha engines are not reliable they will blow up, but you know behind the scenes there is always someone paying to be promoted.
I believe other tests said they had a factory tech map it with the “blue crew response” map for best acceleration
I feel like cable or hydro with a clutch should be personal preference. Yamaha is doing it right with making it and option. If you want hydro, go to gytr and purchase it. Make the buyer choose not the media outlets saying you need it. I remember air forks being the big craze 10 years ago...
Is the offset of the luxon clamps stock 22mm?
Can Jamie fix the Ktm fault of the piston hitting the crank , any revenue in that complaint :)
8:05 Wait. Did you say "cancel because of the rain?" Wow have times changed. Do they cancel your races out west because of rain, too? Over here in New England we'd get laughed at for even suggesting such a thing. You west coast boys need to double check your BVD's to make sure you still have a pair before you get on those bikes. 🤣
I run ultra distance in the rain ,I would love to do moto in the rain as well but not all people think alike.they close the tracks here in socal then again they do get flooded. I salute you guys for having balls and discipline.
Sounds like a digital drz400s 3x3 mod.
Radiators bend like lead. Real soft. very pliable to get back into shape after a good crash. The bars and clamps can easily be straightened out too. thats a huge plus for me as my 16 year old gets faster and faster. Nice job Yamaha
Now how would someone go about changing the airbox and getting the ECU tuned like you guys did? Is their a site I can go to??
Twisted Development
'24 250F is nice and all, but I'm preoccupied with the fact I can't get the '24 YZ250 2 stroke I ordered back in November. Was told it would be in by Dec. 20th, then Dec. 27th, now not until January 19th! Is Yamaha having issues or something?
Yamaha always does that it seems. At least for the east coast guys
We have a bunch over here in SoCal
lol, you’ve obviously never ordered anything new. It’s very normal my friend, just be patient, it will come.
Get a '24 KTM 250SX. You may like it alot better. 💯
@@SosopChabot Supply chain issues lingering in ALL manufacturing. Bit crass of ya fella.
Did he put the dual injectors on it as well? If TD threw that on as well I bet that bike would rip so hard
The 4 stroke shouldn’t be rode all the way up top. It’s better low mid and some top. Better traction in the mid area.
2019/2020 the bore stroke changed.
“New airbox” would have to be an airbox from either a 450 or from a previous model?
No kidding, tell us what specifically changed.
If you listen to Keefer he said that Jamie used a 23’ airbox
450 airbox 23/24^
Is it just me or did the modified bike sound like it was missing on about every 5th stroke. Like a rev limiter but all the time. ???
My complaint is it sits lower then the 19-23 model
It’s amazing that All the testing and development Yamaha does they still can’t get the airbox sorted
Weird how the new kx450 has a problem with bottom end power and the air box is needed to be modified. I hope this isnt a new trend for all new bikes coming out. Dumbing them down
Yoo first at my favorite mx ytuber
Maybe they could make an airbox kit for the 2002 Honda CR250, a bike that really needs a new boot and airbox that seals better.
Wow, Yamaha really didn't like not winning the Shootout at MXA. I pictured them being really insistent in making this video lol
Isn’t the screen on the air filter cage designed to resist against back fire? Which mixed with the alcohol vapors of the filter could cause a fire. So now we are just throwing fuel into the equation in that same area now? Seems sketch.
Twin air powerflow filters are designed for screenless cages. They have a fireproof layer on the inside to stop backfire
@@Cl4rky ah, the chemicals are fire proof?
@@dandlugolecki3408 the alcohol in the air filter oil evaporates once it’s poured out of the bottle and onto the filter, leaving just the sticky oil. The material the inside of the filter is made out of is fire proof
Cali riders call that a wet track 😂
Yeah no offence but l had a 2015 yzf 250 and l thought it was as ergonomic as a gum boot but the motor was a very typical Yamaha motor strong and reliable and way to noisy as l couldn't use ear plugs
No hydro clutch option for the 250?
GYTR missed that boat
Or, just buy a 2-stroke to begin with...
Grandpa Christian Craig
You shouldn’t have to spend 7-8k on a new bike just to further mod it with thousands to make it acceptable.
As riders said the stock bike is awesome as is . There is no "Need" to do anything to it , it all comes down to personal preference.
You won’t be spending 7-8k. It’s $9-11k
I am convinced factory engineers have never rode a single bike in their lives.
1 small change would be, buy a KTM
Star made Yamaha look good they aren't as good as people think
Honda Rider by any chance?
Exhast
Yamaha knows it can gimp their bikes because they STILL CAN.
Cant wait for proper chinese competition to whip them up into shape.
Haha the vet pro pretty much said it's a waste of the money !! Gold
So best bike or the year huh but has so many problems can’t order shit for it and breaks after 40 hours of real use…. Another great shootout report from mxa 😂 meanwhile Honda ktm husky and gas gas even Suzukis still going strong 😂 I’d mention kawi but those pieces of shit fall apart every moto
Things feel so bad and akward. And are so slow. Yamaha pays alot of money in marketing
I thought they rated it pretty bad, n you don’t gotta buy one tf you crying for 😂😂
@@Runk3lsmcdougal the air box and gas tank is the most retarded design I’ve ever encountered on a motorcycle 🤦🏻♂️ complete trash
Hater’s gonna hate
new yamaha n kx are junkkkk go to honda or ktm or suzuki
I busted out laughing when I read your post ha ha ha . Very funny .
Idk what these so called “Bike boys” are hollering but the 2024 is a beast shit if you think you can build or whatever better then go get on the damn assembly lines lmao 😑🤷🏾
WORST SOUND of all bikes
Agreed sounds almost like a kx
It's called a 4 stroke😢
@@panic-revv85 not really....the older models sound better . Like 2010 4T had good sound, now. restricting the sound and how they do this makes horrible sound
@@Motoinc the 2010 generation was garbage.
@@panic-revv85 the 2009 bike was amazing, and AWESOME sound on the older FIM/AMA sound regulations
Put it on the dyno
