2024 Yamaha YZ450FX TEST

#dirtbike #motorcycle #motocross #offroad
We recently had the opportunity to ride the 2024 Yamaha YZ450FX at the Ampro Proving Grounds in Union, South Carolina. This is the facility used by Randy Hawkins to test and train with the Ampro Yamaha Racing Team, and it was a very special treat. The YZ450FX is the off-road version of the Yamaha YZ450F motocross bike, which was redesigned from the ground up last year. For the most part, the FX got the same treatment for 2024, which means it has a new, lighter chassis, a massively updated motor and slimmer bodywork with a more spread-out riding position. To make the translation to off-road, it has a larger fuel tank, an 18-inch rear wheel, a kickstand and an O-ring chain. Most other manufacturers have a model like this, but Yamaha checks a few more boxes. It has a wide-ratio gearbox, softer mapping and softer suspension with 10mm less travel in order to lower the seat height. We spent two days on the bike and then took it down the street to the Big Buck GNCC, where we put it to a real-world race test. Here’s what we learned.

I ordered a 2024 Yamaha WR450F and ordered the competition ECU so I can also program it with a smart phone. I will be uncorking it right away to. The reason I went with the WR is I will be making it street legal so I can get from trail to trail. The FX is too big of a pain to try and make street legal. No headlight and taillight, no speedometer and doesn't put out enough electrical juice to run these things and the WR already has the radiator fan stock. The WR just works better for me.

[@leec48s45]

I looked up the stator part numbers and they are the same this year between tge WR and FX.

[@billsharko3007]

@@leec48s45 Thats a lot better now you can run more accessories on the FX but I still need the lights and speedometer for my trail riding. Thanks for the information.

[@paulf144]

Excellent review and footage. Best I have seen so far.

[@user-tg6xj7gf4p]

wonderful! This season I will be riding the 2024 YZ450FX.

[@briancastora769]

Mine is due in any day. Ordered it in August of 23’. Good thing, I did that when I did. The dealer is only getting one.

[@OtisFlint]

wtf is going on with Yamaha supply issues? Ridiculous.

[@robvanduren761]

1 ????????????????????????????

[@1Fasteddy]

Yamaha has stepped up their game big time with the tune ability of these bikes

[@ronlawson5819]

Another great video,will you be riding the WR250F

[@user-dl2nh2nm1g]

I have the 23 yz450fx. I trail ride the east side of usa. Mostly Kentucky and West Virginia, and in WV you are allowed to ride on the road between trails. This bike handles trails and the road well. The only 2 things I did to mine was the fan, and a throttle tamer. Personally I think the fan should be on it from the factory because it will get hot on the slow stuff. And the throttle tamer completely changed its manners on the slow stuff, it feels like a 350 till about 1/2 throttle then all 450 power. The tamer really took the twitch feeling at low speed away, best 70 bucks I ever spent. I get about 70 miles on a tank of gas, but tires go quick. And because I am not a pro rider it will last for a long time.

My 17 RMX has been great and everything but this is exciting!

[@andychips6923]

I don't understand the adjustments guys say they do with the cable clutches...especially multiple times while on the trail.. I put 80 hours on my fx that I had and never adjusted the clutch once..

[@rochellestanley9532]

Good stuff..

[@moto3463]

I need one

[@travisbates6049]

I want to try Woods racing on a dirtbike I feel like the YZ250FX over the 450FX I am a 192 pounds I ride a ATV with a 450 but I feel like I dont really need a 450 for woods racing I want to get a Yamaha soon

[@Sers0812]

How hard is it to turn a standart 450f in a x version? Unfortunately we dont have the x versions here in europe

[@brianh8484]

Gearbox would be the biggest and hardest thing to change. FX has the same gear box as WR

[@rickywoods3101]

They need 3 maps for a full power. I want to be able to play around on full piwer mode and hit the mx track every now and then

[@excitedwhale]

Looks like the 250 didn’t get those updates?

[@paulf144]

Next year.

[@ronlawson5819]

Imagine if they built a 350FX

[@stephenbrown3760]

Use the tuner and dial it back

[@OtisFlint]

@@stephenbrown3760 Can't tune inertia out of the rotating assembly.

[@BAYAREAMX]

They’d sell every 350 they made. I don’t understand why they don’t make a 350.

[@Zen_Garage]

Add a YZ300X to the wishlist...

[@KingofKahkis]

@@Zen_Garagelook at Fantic bikes. That’s exactly what you’re talking about

[@toddjacobs5660]

Put Grahm Jarvis on that thing

[@306TurboFox]

Yamaha just needs to come out with a 350 already

[@DirtBikeMagazine]

We heard a rumor that a while back they were considering it. This was early on when KTM had made theirs. No talk of it since

[@nicholascanjura5051]

Look at that freshy

[@steveperelli3602]

Why don’t you make Yamaha pink it would look better

[@steveperelli3602]

I like Honda better than I like Yamaha I like Suzuki better than I like Yamaha I like Kawasaki better than I like Yamaha I like all the big better than Yamaha I do not lake the blue but it’s OK

[@steveperelli3602]

I like all the bikes better than Yamaha because they’re not yellow anymore they will never be yellow again

[@steveperelli3602]

It’s time to go back to the drawing board with that bike
