When your boots have their own ruts I’d say you’ve ridden it once or twice

This guy is a highly skilled rider and can make the most of the 450's strong engine. I am a competent novice, and did this same experiment and had opposite results, I was a little bit faster on the 250f. If you are just riding for fun, get the 250f.

Really good comparro, I did not expect the result to be so close. Thanks for the high quality vids Adam. The kids and I thoroughly enjoy watching them over and over again.

Out of all the KZfaq channels out there, by far you are my favorite. Keep up the great content.

Riemann your skills riding the bike, informing the viewer are number 1. Your ability to hype and inspire is only matched by your editing skills. Seriously you could do a 4wd adventure style show for Enduro/motorbikes. Jace and Simon cld even cameo. Keep uploading man, we love it!

Really love these video's. Keep up the work Adam!

Awesome looking track and solidly honest feedback. Another quality video.

Great video, only been subscribed for a few days & very much glad I did!

Always enjoy your videos. 🤙 keep up the awesome work!!!!

Most underrated channel on KZfaq. Great video as always

One of the best WR reviews out there! You nailed it mate🔥

great comparo and man what a loop youve got yourself there 👌

Another great video 👌 Thanks for sharing. Would be great to run a range like Sherco around the track on the same day and see how they go too. With the 250, 300, 450 and 500 all very similar in the frames, it would be interesting 👍

Not surprised a top rider can go slightly faster on the 450. But I think most mortals will have a better and safer time ringing the neck of the 250. Also I think this video makes a good point as to why 350's are so popular now.

Very interesting! I did not expect this result at the end. I rode the 450 EXC a lot in the past. Now I am on an 350 EXC, which is really the best from both sides and just perfect for me right now. I added an HGS Slip-On Silencer, which had the effect of a bit more Power in almost every RPM, and bit of less wheight. The sound was not a factor for me. But it isn't bad though. Greetings from Germany. I watch every single video and really enjoy it every time once again. Keep it up that way. 🙂✌🏻

Smooth riding Reimann - nice creative track in your backyard has a bit of everything.

Rough at your age maybe, but you still know how to rock a bike. And you track has everything but a swamp, and I never did like swamps, so your test made much sense to me. Keep on keeping on, and I'm glad to see you looking healthy.

Great riding Adam, would be happy riding either bike. 👍

Hands down mate you make the best dirt bike videos on KZfaq 😎👍

Great video I have a 2020 yz250fx Yamaha and a older 2014 wr450 . The 450 is more of a open desert bike and the 250fx is fun and light everywhere and doesn't wear me out as quickly but on long fire roads it tops out quickly . Great video..

Good comparison, and I would have guessed the 250 on that loop. I have a slightly tweaked 250 and love it. I found the 450 a bit of a handful when trying to go fast, but that is a rider issue.

As always, your riding it excellent, super humble, please come to America and road trip to all our different terrains. I am sure many riders like myself would help you on this journey. I will say it looked like either you or the 450 was making it look effortless in everything but the logs. Where as the 250 seemed to be the opposite, floating over the logs and scraping for everything in the corners and straights.

I would like to see the same thing comparing a 150 to a 250 or 300 two stroke.

For an old bloke like me who rides singles to tough singles it all comes down to the Fun- Factor, so The 250 would be My choice forsure. At the moment I'm still lovin My 250 2 stroke.

loved it, again well done!!!

Thanks for the video, I'm not as fast as I used to be, I love my mates YZ450fx, but it's to much for me, lol (except in the sand) I cheat now on single track with a FE501 !! Tamer than a race 450 and more grunt than a 250, although I'm shocked how fast the 250s are. A FE450 would suit me as well. I just sold a KTM 350 exc, good bike too, but I missed the grunt of a 500. I sure enjoyed the extra range of the 350 though. I sure wished I had a garage full of bikes, they all ROCK!

I got a 450 as a novice. Learning was hard but love it. In the tight places I am still slow but on the soft, difficult and bad stuff I fly past the 250's. Just love it

I noticed the boot ruts as well, awesome flog session for the boys in blue. Great real world comparo/ content. Setting the testing standard for dirt bikes on this clip, stop watch does not lie. Did miss ye old CR, probably would of put a dent in that 450 shine.

You looked faster and more importantly comfortable on the 450 in my opinion mate the 250 seemed to struggle off the bottom a fair bit and unless you're a pro level rider it's harder to keep it in the power. I have a my19 WR450F it has the GYTR exhaust FMF muffler etc I actually went back to the OEM muffler and left the GYTR header pipe great combination it slightly detuned the bike even changed the intake sound probably due to more back pressure. not making it bark straight off the bottom made it heaps more fun to ride I found map 2 slightly detuned it a bit more and use it for extremely snotty hills I took the insert out of the muffler and now find it hard to falt. I was comparing the 2 myself and thought about downsizing to the 250 for deep bush riding or with the 250 and 450 being so similar maybe re sleeving it to a 350 now I'm waffling on 😅 great video thanks for sharing mate cheers Happy Trails oh I really like your riding style wish I could rail berms like you do 👌💣

great vid, well shot too !

Nice one Adam 👍. I think it definitely comes down to experience, strength and fitness. You're a strong, pretty fit bloke so a 450 suits you well and you can milk it. A newby, scrawny or out of shape rider will probably do better on the small bore

Awsome video man thank you

I jumped on my buddies 250 last weekend and it would be great for the riding we do but it made me appreciate my 450. The 250 does good but my 450 is pissed off. I love the adrenaline shot the 450 gives me.

A great comparison. I've often lusted for a WR350f or atleast a 300 based on the 250 engine / oem stroke number.

2021 wr450f is a joy to ride. Worth every penny!

Awesome track you've got there!

Good one, eh !! When are you getting back to India... Loved you and your Dad doing the Himalayas

Hey I didn't know were WA Enduro champ. Respect. Epic chat with Jase BTW.... Now I'm off to get the MotoNomads. 🤙🤙

I enjoy the construction of your experiment

@3:00 that hop over the turn, then riding through the turn is freaking sweet !

Damn that 450 really snarls. Good riding, really satisfying to watch

great vid could you do same test again with full race exhausts on, be good to see any difference in times etc.

You were definitely on the pipe more on 250. I love lugging a 450 though. Torque is fun.

Imagine a WR 350

I've watched this video several times just to get my WR fix. Had a 250F on order for quite awhile!

Nice track, also nice video man

Amazing Work

Love my 450 she’s all geared up high speed desert racing and just change map and plug up one air intake and she’s good for single track. One of the best bikes going around at the moment

You have got to be my favorite Australian rider

I know a 250 is faster in my type of tight bush riding. BUT I love the tractor of a 450 and you dont need to rev it to go places. A 450 you can still be low rpm and smash out a corner. A 250 needs a clutch blip or a downshift. My next ride will be a 350.

Hey Adam, great comparison on the WRs. What about the same format for KTM 450 vs 350? Great channel. Thanks for the blood, sweat and tears you invest!

Can you do a comparison between the WR450f and a TE300i? I realise they’re completely different bikes but it would be cool to see your thoughts comparing the two and who each would be good for in the bush. Also include your thoughts on the commute to and from the trail, on the road for those that have a trail close to their house or even the commute to work like me. I only live 5 mins away from home and when the car is out of action i would take the bike.

just commenting to give you a boost! dont care which is faster, thanks man.

thanks for a great comparison on these two bikes, but no wide open 1 mile time contest? that one needs doing.

Wow, just a few seconds in it!

Welcome to your second country, Morocco, where there are very beautiful landscapes

Thanks for this, I’m tossing up between crf450x and 250x and I don’t care about a few second so I think I’ll go with the 250

Would love to see this comparison with the 2022 WR250F with the new frame etc

Excellent it’s a question if been wondering about like many others I am sure, I had an older 250 RM 2 strokes then I bought a CRF 450 which was really torquey but seemed heavy compared to the old 250 so I sold the 450 and bought a CRF250 and it was not much lighter but just didn’t feel as good as the torquer 450 so I sold the CRF250. Now I have a project ATK406 and I would like a 450 again.

Great video and awesome riding skills. The test should be done on uncorked bikes. From the factory, these bikes are tuned waaay down. Unplug the intake and exhaust and see what happens.

I have two KTMs, identical year and chassis. 250 2 stroke and 450 4 stroke. Riding conditions like this on the 450 I feel like I'm riding sloppy, making mistakes, riding slow - and then the stop watch surprises me every time. I'm slower on the 450 but not by much at all. I think the 450 just makes up time out of every corner even if you feel like you're riding like crap. I find myself sitting a lot more on the 450 even if I try to avoid it - I noticed you did this too (rock garden). I stand 99% of the time on the 250. Ok, so the bikes feel different but have similar lap times. BUT the 450 is a work out to ride. My knees get chaffed from holding on which doesn't happen on the 250. It would be interesting for you to do a 2 hour harescramble on that loop on each bike and see which you find more enjoyable after doing that (a week or so apart of course!) I also think that the newer the rider, the tougher time they will have with a big bore. A new rider will learn better on a smaller bike and that will bring more speed for them.

Nice work👍👍

I know where the stopwatch came out, but you looked so much more comfortable on the 250. Maybe you were tired when you got to the 450, but there is a big difference in your riding behavior on when approaching obstacles between the two bikes. On the 250, you were riding it, and one many occasions on the 450, it was leading you. Maybe your answer is that Yami needs to build a 350. :)

had 3 x 500exc now the ec 350f feels like the perfect balance of power to weight ,suits me better at 65kg - 52 years old not getting any younger ,at end of the day less fatiguing to ride

Great video

Dude is ripping it hard. 🔥

WR are awesome Bikes, for the Novice or seasoned rider. Here in the States we have to uncork them to get their full potential. Still wish they had an ECU Map system for the Stateside Bikes.

Nice Video! What about rear Tire Size? Are they exactly the same? If not I think that might also have a minute factor...

You are right about the 450 if the rider is up to it . I have raced both classes in the past and now retired from racing enjoy my 2021 WR250F because it’s light and doesn’t wear me out like a 450 will do . But pushing a 450 hard with a skilled rider will give you wins ! Most blokes can’t ride the 450 to it’s full potential and will get hosed by a WR250F.

Depends on the track, if it’s bigger and open the 450 all day

Adam another great video. I've been looking at both of these bikes and have been on the fence at what to go with. Currently riding a 350xcfw I'm worried I will be disappointed with the power of the 250f but having rode a 07 yz450f in the woods for years that would tire me out I don't know if want to go back to a 450. On a side note here in the US these bikes typically come with a very choked up exhaust for emissions and are super quiet that usually gets the insert removed before riding but your bikes sounded really good and not choked up at all. Did you remove the insert or do they just come with a less restrictive exhaust in Australia?

Spot on mate

Yes finally someone who does not poop on the 450 well done !!! braaap

id love to see you compare the yz250x to the wr450. at least for the same track time comparison.

I have a 2018 yz450f now i know it is NOT a woods bike, its a complete animal to wrestle in the woods. I could have sworn you would have been faster on the 250 just because of the weight difference and being more controllable. Good job though nice to see someone not shit on the big boy for once. Hell of a job Sir!

Proof that what you need to do is pick the bike that you like best and go riding!

Its a shame this bikes cant be street legal here in Portugal anymore...i was just close to get one 250...hope the Yamaha can do something about that...great vídeo 👌

As a 215lbs athletic guy and 6ft I enjoy the blunt force trauma of the 450. If I feel I need fast and sexy quick I can muscle the 250 much better. I have one of each and I probably ride 450 2 to 1 over the 250. But when it comes time for me and buddies at the track it’s 250 all day because I want to beat their asses. Great video

My 500exc forever 250 /350 never. I think you pretty much nailed it. The 500 does all the work. When I ride my 350 I do most of the work

Wow...you are an amazing rider...I'm pretty sure you could give Jarivs a run for his money! To me you looked smoother on the 450..more flow. I wonder if the flow of the 450 would tire a rider out less than the lighter/flickable 250 over the course of a 4 hour enduro?

Both are great 250 s seem very friendly to all users but still fast when you are experienced but just want to know if there is a big difference in reliability

Hey Adam thanks for vid.What if you had to do 10 laps non stop.Im thinking fatigue.?

My buddy had the wr250 and it's real slow when compared to my crf250r but they are meant for different types of riding. However his bike handles soooooo well that I'm actually able to ride his faster than I can mine because on the wr I feel way more confident.

I just test rode a WR450F today. It has HILARIOUS POWER. As in HOOLIGAN amounts of power. Absolutely ridiculous fun. Gets very hot quickly though, even with a fan installed. In addition, I also rode a WR250F, back-to-back. The 250 felt like it could the same things and more than the 450, although albeit with much less power, but still very fun also. I'm torn between the 2 as they're both the same price. Hilarious, hooliganish fun at the expense of fine control in the tight, stuff? Or sure-fire all-around weapon, at the expense of high-speeds on the road (and fast trails)?

I knew figured the 450 has ton capable of and it is a lottt of motor for intermediate rider for trail and can get wear out quickly when not too familar with the power compare to the TTR bike. So thankfully I'm end up getting a WR250f which to be suitable and proper choice. The 450 goes after mastered the 250/300cc with bunch of hours in it. Just bringing the realistic for the beginner/intermediate rider who's looking for move up to the big boys bike.

Can you please review or get on some yz's to much four stroke stuff. But I'm happy regardless keep up the great vids.

Would be good to see it on the mx style track

Maybe 450 4 stroke vs 250 2 stroke.. the new Yamaha's please :) ... Great video btw

My first thought before watching was, whichever goes last will win. You created a better run to ride in.... and that's how it ended up.

Do these bikes come restricted from the showroom floor, and have you removed intake snorkel, exhaust baffle, and throttle stop if so? Not sure if they come like that in Ozzy/NZ stock, or if that is a USA thing

Perso i ride a WRF 450 "18. Before i had also differents big power enduro or motocross bikes so i'm just used to ride with it and if i had to downstep in a 250 or else i dont even know how to use it because the powerband is so different between both of them... the only problem of this things is to manage heavy muddy terrains😅

Faster has so many factors, rider, track condition and guts😁 It all depends. Screw small engine and go bigger. 450 all the way. Subscribing. I think I found a good channel by Recommendation from KZfaq.

Good video

Didn't think it would be so close, would love to see the comparison of the two on your mx track I think the 450 would be much faster there. Great video as always keep up the good work.

As primarily a desert rider, the size of the logs on your course just look impossible. Got a 500 partly because of you and your videos, but have recently made the decision to give a 2022 KTM 300 XCW TPI a go. Love my 500, and will miss it.

On the next vid can you post your camera setup?

Do any of you folks know if the Aussie WR's are the same WR's that we get in the US? What we get in the US are fairly choked-up, i.e... throttle stop, filter snorkel, milder ECU settings, etc.. I realize all this can be addressed with GYTR or other aftermarket companies, i'm just curious. @ARieman1, awesome dirt/terrain on your property mate. What a killer place to ride!

I wish you could of put the yz250x in that matchup. its between the 2 in horsepower but lighter. the other reason is I own the 250x and would love to see how it compares.

Would love to see your time on the 350’s KTM , BETA, HUSKY would you be faster again?????

Very nice.
