So yes, I have weighed heavier bikes on my scales. I’ve even weighed heavier two stroke dirt bikes. But that is beside the point. The point here is that this 2023 Yamaha YZ 450 FX is literally 6 pounds heavier than its Honda counterpart. 6 pounds! I wonder where, in the world all of that weight is. In this day and age of trying to get the most power with the least amount of weight, I think 6 pounds is pretty remarkable. I’ve said it before, though, weight on the scale, does not always translate to wait on the trail. there is a lot more to this than just meets the eye still though,

450fx holds 2.15 gallons while the rx holds 1.69 gallons. 1 gallon is apx 6 lbs. .5 gallons more in fx means 3 more lbs.
So really it is 3lbs heavier which I wouldn't be surprised if that's tied up in radiator coolant, wifi type add ons, 6th gear, or the oem silencer.
Yz450fx is a 5 speed but the rest of what you suggested likely is the extra weight.
Gawd I love my 2018 yz450fx, all 260 lbs of it. Best bike ever. Threw away my KTM and haven't looked back.
Yamaha is built with better materials lol
It has got to be climate change.🤔
Claimed wet weight of the 2023 YZ450F is 242 lbs. Claimed wet weight of the 2023 YZ450FX us 256 lbs. It is known that one of the big differences between "X" models and the motocross models is the addition of a coil to put lights on it. Gas tank YZ450f = 1.6 gal vs YZ450fx = 2.2 gal. 18 inch tire on the fx, that will add a little more weight over the f model. I suspect this is going to be just a bunch of nit-noid stuff that made the difference.
Yamaha = reliability
Love my 2020 Yz450fx. Yes they are a loud bike. The bike revs to the moon. When you think it’s time to shift hold it open little longer, and it will shock you how much more it has to offer.
Very cool. Can't wait to see the 24's they're hopefully gonna get the refresh that the motocross 450 got. Sweet!
From what I’ve read about the 2023 yz450f, I’m not sure they’d do much to them to call them an FX. The new ratios and higher rev limiter pretty much make it the perfect platform for enduro/mx/trails and bassically anything you want to do with it.
The only changes they’ll make would most likely be bigger fuel tank, bash plate, hand guards, and possibly an 18” rear wheel instead of the 19” they run on the MX bikes.
Yeah, my first single track dirt bike was an XR650R! My learning curve was STEEP but it was fun. My favorite was a KTM 450 MXC...plenty of power, loads of traction, decent suspension and not tiny feeling like the 250s.
I’m riding a 19 450 FX ice racing and it’s an amazing bike and I ride a 22 for enduro love em
I have a 2017 yz450f that hated until 2 days ago when i changed gearing just added 14 t sprocjet insted of 13 and changed the whole thing amazingly
I love my 22 450fx it's a time machine!
Awesome you got the 450fx can’t wait for some riding videos with it. And I hope I can win it too!! Keep up the great work sir.
What weight would you expect for a 450 4T?
225 lbs? Should weigh my CRF450X now that you mention it. After a quick search it is something like 250 to 275 lbs :(
You can definitely expect them to be on the heavier side, but it is interesting that the Yamaha is 6 pounds heavier than the Honda.
@@ammonatamanczyk6481 part of the additional weight of the Yamaha could be the extra camshaft.
The Honda is a SOHC (Unicam) engine, so majority of the weight might come from the Yamaha's extra cam and larger head.
Are they still 5 valve? If so there's a little more weight too
@@joshpodolsky7740 not anymore, Yamaha went to 4 valves on bikes in 2010.
While I can say What it’s heavier than the Honda, the new gen motocross version of the Yamaha has lost some weight, so I bet when yamaha updates the Fx version it’ll also lose some weight.
Well, it’s a 450. So there’s that
Best bike ever. 6lbs aint shit
Next years model will be 7lbs lighter! The 450fx is a awesome bike, gobs of power and 1,500$ cheaper than any KTM
What bike you ride and all
The aftermarket parts won’t matter as much as throwing your leg over the seat and riding. I ride with all sorts of riders and bikes and the best riders are the ones who put time on the bike not time in the shop. I ride a 2019 450fx and can do any trail or obstacle as the 2 stroke guys , mostly cause all they do is talk about how great they can ride and don’t actually ride.
I have the 2022 and I love it, Iam faster over all for hard enduro courses that have fast flowy sections power tuner app is awesome just gear it down to suit your purpose I came off of a 2017 xcw300 with sx 300 head and cdi. great for tight n tech but not so much for faster trails, the 450 fx is about as tight n technical as you are gonna get in a 450. I had an 08 husaberg fe 550 which was stinking amazing and hard to beat with anything.
You have a 450 on the channel because you screwed up and got that Honda 450 and fell in love. You didn't like them because you were unskilled and still had your toddler pants on. Now you're skilled and wearing big boy pants.
I love my 22 yz450fx and have very few complaints. Other than being a bitch to start in the cold weather it’s been awesome. It might be heavy but it’s still agile. My previous bike was an old 04 yz250f and comparing the bikes, the 450 honestly didn’t feel that much heavier. I obviously can’t flick it around quite as much, because of inertia. The most notable thing was the power. It wants to rip my arms off out of a corner at times lol. And it definitely wears me out faster. I’m mainly a desert rider so the 450 is definitely my go to. but if was gunna head to the woods for the day I’d probably want the 250, just because the lack of power is so much more forgiving. Lol why not have a bike for different riding styles. Still have my old 250f now I’m looking for a 2 smoker next lol. Gunna have one of each eventually
Dumb question for you, but since you mentioned it being tough to start in the cold, are you using the cold start (choke?) option? I had trouble starting mine (also a 22' 450fx) prior to using the cold start.
@@x_Heffe_X the only time I’ve had the issue is when it’s about 30 degrees or less, I’ve used the cold start but that doesn’t always help. Ive found that putting a little tension on the throttle sometimes helps. And I don’t mean opening it just taking the few millimeters of free play out of it. I think the bike just gets flooded, and with a fuel injector its a little harder to clear it out. It also has an over cooling problem when it’s that cold outside. It’s hard to get it hotter that 120 degrees while riding. At an idle it gets up to running temp just fine but as soon as you start riding it cools right down. But I get around that by partially blocking the rads.
@@sethmurphy531 Gotcha, was just checking because I was starting mine in the low 20 degree weather recently just fine once I pushed that cold start button in, sounds like you found a workaround though at least.
I rode mine the other day in 28F weather (22 WR450) it would crank then the starter would spin free. Was a pain to start.. was kinda surprised, almost think that the battery wasn’t supplying enough juice.. didn’t feel too bad though, my buddies 22 kx450 was doing the exact same thing haha. Took us a minute to get started (I tried the cold start on and off) once it was running it was first blip of the button and it would go. I’ve started it before in about 40F and it fired up without any issue 🤷♂️
@@evanwilliams6352 yeah any time it’s gets into the 20s it doesn’t want to fire. It could be a battery issue but I’ve also found if it stalls while it’s cold or warming up, the problem gets worse. I think it’s just getting to much fuel and the stock plug may be a little cold. I’ve been thinking about trying a hotter spark plug to see if that helps. But like just like your WR, once it’s at running temp the problem goes away.
No need for a 450 on the trails unless you're desert racing.
Sometimes it's nice to ride a little lazier. I much prefer to ride a 450 when I know I'm going with slower friends.
Great bike, look forward to the ride review
Probably that big stock muffler.
Kyle This is a review that matters... Please give us more detailed info on handling, power profile, and how it compares. Hopefully it will have some more definitive info than the "un-review" of the Hondas. There was almost no useful info in your review of the Hondas, particularly the crf250rx. Still a fan Kyle, keep it up.
At 6:09 it looks like there's a dent on the silencer. Is it supposed to look like that?
I am guessing it's 6 lbs heavier than the honda do to the exhaust muffler, the frame maybe thicker, and Yamaha has two camshafts in the motor instead of single cam in the honda.
Well for starters the exhaust wraps around the engine which is not nessesary. My 2022 KX450 the exhaust comes out the front of the engine and same with all the other manufacturers so why does Yamaha have there exhaust come out the back and wrap around the left side then run down the right side towards the back? Doesn't make sense, that's just more metal exhaust on the bike then needed.
With the tuning app it can be what you want it to be.
Will you still be getting the TM? Really looking forward to your thoughts on the TM!
Longer exhaust pipe is probably a pound or two
Here I am with my 2001 WR290F... 250ish lbs and I consider it a lightweight lol
2 L more on the gas tank and 1 inch more of rubber tire
did the honda have push start
The extra horse power weights its down
did the honda have air forks ?
One reason it is so heavy is that it doesn't seem to be based on the totally new 2023 YZ450F but on the previous generation of YZ's. Funny because normally FX's do not lag behind like the WR's.
I think its stupid to weigth bikes with full tank, u can vary the amount fuel u use and fuel capacity it a merit by it self. Bike should have empty tank, but wih all the other fluids that are needed for riding, then u would know the real weigth of bikes
March 2023 sweepstakes? Not 2022.
Dream bike, converted supermoto!
Why is my Yamaha YZ450FX SO HEAVY?
It's a four stroke.
Marketing negates the need for technical excellence, particularly on four strokes.
It's a four stroke.
They are going after the Harley market with trail hugging weight.
It's a four stroke.
It's not a two stroke and therefore irrelevant.
6 pounds makes no difference on a dirt bike.
🤤🤤🤤🤤
Kyle, the review a lot of us would love to see is a comparison / shootout between a 390 Beta and Husky / KTM (TE 350 or XCW 350). Heck throw in the 300 Sherco 4stroke. These are popular bikes and no one to my knowledge has pitted these mid sized 4-strokes against each other 👍. The magazines are too afraid to do it.
Kyle, for my two cents, I agree …. Would love to see this comparison/ review of these bikes. Keep up the great channel.
I agree too
I agree too
fe350 kyle!
Agree!
Yamaha 4 strokes have always been heavy. Yamaha reliability is worth 6 lbs. It looks like a pig on the scale but does not feel like it on the trail.
I race a 2019 YZ450FX so I can at least speak with a BIT of knowledge on it. It's little stuff that adds up. The WiFi module and the wiring/switch that comes along with it. The motor is a dual overhead cam setup vs the Honda has a single cam so all the extra valvetrain components that come with it. Obvious there's other stuff, but those jump out at me right away.
I just picked up my 23 450fx about a month ago. I've got right at 7 hrs on it so far. Coming from a 250x this 450fx is an absolute animal. Very pleased
The extra letter in Yamaha over Honda is approx 6lb
Don't worry about the 6lbs....that's a bad ass bike!
It’s the balls on it!!!
I just picked up a 2023 YX250FX after 32 years off the bike. Local Honda dealers had nothing in stock so i went Team Blue. I love it so far after 8 hours on it only.
Dual cam vs single cam. Wider piston/smaller crank versus the Honda (basically an over-square setup to be able to keep the valve lift/spring tension to a minimum while keeping valve flow area - all have implications for the total mass of the head). Longer silencer (at least it used to be), and probably longer total exhaust length. Electronics modules for the Bluetooth stuff. Probably taller radiator height. Also if they boosted their electrical output from the 22 that flywheel rotor is probably a brick too. A carryover from the first gen FX is also a huge brick of a starter clutch. Got lighter in gen 2 but still not "light". The WR trans gearset I don't think has changed for decades and is probably still heavy too.
Heavier bike, but it won't rattle your eyeballs out of your skull like the Honda. Racking up hundreds of hours thrashing my 16 FX around and it's not going anywhere, despite its quirks.
You say the FX has the WR transmission? 🤔 did not know that. I knew it was different than the F model
@@evanwilliams6352 The FX has had the WR transmission from its introduction in 2016, so I'm assuming the 2023 is the same, but I haven't seen a deep dive on this model year yet to confirm. As I recall, those gear ratios and part numbers were heritage part numbers from very early WR426/WR450 parts sheets. It would be nice if this bike got a thorough top to bottom refresh, but I doubt they sell enough of them to warrant that.
@@gordonhill28 the 1st and 5th are the same as the WR and the rest are the same as the F version. i own one and for fast trail its a monster even in the sand it goes well but on track it feels like a tractor....oops commented from the wrong channel😅 ...Acadianhoons his the channel where i post all my dirtbike stuff
Now this is the kind of bike that I'll enter the sweepstakes for... even though I already have a 2017 YZ 450F... worth it
The same here i hate mine hahah but realñy want electric start and calmer feel
Cant wait to see your thoughts on this bike. Not that i would buy a big four stroke bike for myself but i am always interested in all bikes. I am a yamaha fan as well.
6lb,means built to last.(extra fuel?)
Maybe next time a WR in either 250 or 450
I have the 2020 450fx please try different tunes it actually makes a big difference
You're going to love it. I have the 21 450FX and it rips.
Is fuel capacity the same?
6lbs of more quality
Open it up on the straight point it up a hill and find the tight switch backs you won’t be disappointed!!
Finaly something is not orange
Durability 4 stroke 450 vs ktm 300 2-stroke and cost of rebuild? Could you please do a ktm 500cc 2-stroke build and review. Thanks....BRP in Canada 🇨🇦 I believe is one company that makes the kit for most current 2-stroke 250cc models. Just thought a 500cc with EFI and counter balance would be a blast to ride, be worth gearing up a tooth in front for the desert. 😉
Thanks Kyle.
Holy crap look at the size of that muffler! A silencer would probably drop 5 of those 6 pounds!
Change the exhaust and rear sprocket, will help reduce some weight
My real question where is the 6 lbs of extra blubber on all of us 🤔🤨
Maybe the tires ? Battery ? Extra fuel ? Maybe she like to eat ..
"this is the big brother and son or grandson of..." Yamaha has one messed up family.
Why ? I didn’t get the answer from the video
small price to pay over a Hondog
Mine is a '19. It has a dry break 2.8gal tank, wrap around handguards, etc.
It may be heavy but that also means that when I gear it 14/49 and race wide open desert races at 80mph it's one of the most stable and powerful bikes on the market currently. Horses for courses and all.
She’s “ thick “ 😂
Cant wait to see what you think about it!!! cant wait for the sweepstakes!!!!
Kyle, been watching your videos for 3 years now, you almost persuaded me a few times to get a KTM. Last year I went and bought a 22 WR450F and it’s been a BLAST over the last 600 miles single track / hill climbs / tight technical trail riding that I do. I’m excited to hear your thoughts on this bike which is quite similar to the WR
Hey mate 👍 do you reckon we'd ever see a 2023 Beta on this channel? In Australia, a 300 TE by husqvarna is $18,200, and yet the Beta xtrainer is just a tad over $10,000. 😳
What size fuel tank does this have ? For a more accurate comparison maybe you should just put 1 gallon of fuel in each one so the fuel weight is the same ? I have said this before on previous weigh-ins, that aside Honda and Yamaha can’t compare to KTM who seem to shave every ounce / gram from everything they can ….Ready To Race !!! 😂
The FX has a bigger fuel tank because it’s an enduro model.
Compared to the Honda. The KTM run a single cam engine and they shave a bit of weight there but makes less power. This is nit picking when you get into this stuff. Only few riders can ride and if these bikes to their full potential any way
My buddy has this bike (can't remember if its 22 or 21 model), but 3rd gear is and amazing gear in this bike! You can go to a track and almost keep it in 3rd gear most of the time! you can go on a faster trail, and keep a lot of it on 3rd gear! Fun bike! Am kinda looking at a new 450 bike (this bike, the Honda 450RX, and the new KTM 450 XCF-W are on my sight)
Im going to say the engine
The exhaust requires an extra 8" of wrap around.
The 19 Yamaha I had...not only was it 10# heavier than everything else, it felt 30# heavier. It was a great bike but a total tank !
Very nice buddy can't wait until drawing id love either one !!!!!!
It's a race bike chances are you don't notice the weight once you're movin at hare scramble speeds.
Hey kyle had a few of these and love them. The best mod for me is a restrictor in the exhaust, maybe a fisch spark arrestor is the best way to mellow the power and throttle response enjoy
It's gotta be the muffler and the forks. Doesn't the honda use air forks and the yamaha uses spring forks?
yay lets go
My son’s 22 Wr250f sux for tight mountain (east Tn) single track.
-heavy
-power off idle is weak as hell
-waaaay too stiff
-bends shit up every time it’s dropped
-cranks/starts slooowly
I hate it and can’t wait to swap it out for another KTM.
2023 kx450x claims 246lbs wet weight 10lbs lighter than the yz450fx and 3lbs lighter than the crf450rx 🤔
After owning one, I should have gotten a 250. Lol
Just a thought. Since you review bikes for a living how about finding out why it's heavier and making a video on that? Better than asking the viewers who come here for information on bikes and would make for a more interesting video.
Great to see a different color! Have you thought about doing used bike reviews? Best 2 or 4 stroke under 5k?
Too many variables. Not to mention the previous owner's idea of a rebuild. So yeah if you had 5k and really wanted a used bike I'd say do some research and shop around. Plenty of bikes can be had with good stuff for 5k. But at that point if you wanted a full size entry level bike you can get something like a crf230/250f, klx250, etc. Or make a fat down payment on a kx250fx or a decent down payment on a tc/xc etc
Cant wait to see how this compares to other bikes of the same caliber.
Tear both down and weigh each section of the bike to compare
Two things website seems a bit behind. At least it was just now when I was there. Also this will sound strange but I would love to see your take on the Kayo 250 2stroke
Isn’t the 450 F not a lighter bike, the bike, Tomac uses that bike supposed to be in the 240 pound range
450 to much bike for most people, so are the 250 and 300 2T !!!!!! whats your point |?
Honda is more of a MX bike with some Enduro mods. Yamaha's have made them for Enduro and off road. Transmissions are different etc.
Got a 23 WR 250F compare to my 20 KLX 230 its gonna be a 50lbs less but the bike is Higher so Lets see
