Living With The 23/24 Yamaha YZ450F And Things You Need To Know! 

What would we do without Keefer! This dude keeps it real 100% 24hrs and 365 days! Nobody in the testing world does it better.

When you guys purchase stuff on Rocky Mountain ATV/MC make sure you use this dude's link off his website to purchase stuff. Helps support his fam's racing. Gotta keep this sport alive!

I'm a quad guy but can listen and watch your stuff all day long. I'm a nerd for the details and suspension setup.

Thank brother. This stuff is insanely valuable.

You are spot on with those 3 suspension companies! People may have luck with others but the three you mentioned are consistently the best.

As a 6’2 guy I ended up with-5 -5 raptors even still. Really helped me, was getting bad arm pump on the with the stock bar and pegs. Went to a 999 bend. Forward mount flipped back. -5-5 pegs. Enabled me to get up over the front without feeling like the bars were in my lap.

Kris, thanks for all the info! On the 23' YZ250F and thinking of going to the 450 next.

Oh, keep us posted on fuel used too. Thanks!

Liking more content on this channel. Good work keefer!

I think the key to getting the factory front brakes to work effectively, is all in the lever adjustment. I set it as soft as possible, while still being able to lock the tire up if nessessary. If your not used to that soft feel, and jam on them like a freak. It's your own fault. The old model has a way better clutch. I barely use the damn thing. Once I'm moving, I'm only blipping the clutch during certain shifts. Otherwise it stays engaged at all times. I've always felt that having to constantly feather the clutch. Means your on the wrong machine for the job. It's either to powerful, or not powerful enough. How can the engine put the power to the ground. If your constantly interrupting the transfer of tourqe. Same with braking. If your always jamming on the brakes, your in the wrong gear at the wrong rpm. Being in the right gear before you enter the corner is everything. If your frantically downshifting while in the corner already, you've lost all momentum.

Great info thanks again mate!

Thank you for the video, and good info!

It makes me feel better to know that I am not the only one with a boot fetish!

Fantastic video, a lot of great info in this video! Sounds like I'll be going with the new Yz250f and do a vortex ecu and exhaust to get a bit more power since this 450 is such a powerhouse

Just picked up a 24 YZ450F. Honestly after my KX450X Im almost considering tossing an 18 inch rear tire on the YZ450F for MX stuff

Kris... Thanks for showing us where the water gets in the handle bar switch.. And by that, I mean thanks for putting Heather in the frame 😂

Appreciate the transparency

Keep up the great content Keefer!

Thanks Keefer!! Oh, and at 18:37 there is a great cleavage shot. That can't be accidental.

Thnaks!!!!

Keifer is the best, thank you!

My seat hurts my ass to I said the same thing.. didn’t know u could go with a fatter seat and I’m trying those motor mounts too

Дуже велике дякую! Класне і корисне відео! Хочу собі брати такого велосипеда! Дякую за підсказки! Лайк і підписка!

I hear the JBI suspension is really nice

actually a great video, thank you!

Kris, just to inform us, how much is a preventative rod replacement w/ labor through someone like Chad @XPR? And BTW, don't worry about length of videos! These are SO good, that if they were 30 minutes, we all still would invest the time and enjoy. Thanks!!

Awesome video. Now im a lil nervous about my 2023 😂 How come you don’t have the FMF spring connecting the header to slip on?? Last time i didn’t have it on the header ended up moving a lot and then cracking the rubber mount bracket..

THANKS !

Sweet bike

let's not for get to reroute the oil breather hose so oil doesn't go into the airboot and throttle body if you end up upside down!

Always enjoy your videos. I have a buddy that just purchased a 2018 WR250F. It’s all choked down so he was going to add a Vortex ECU from Twisted, but evidently there isn’t any mapping that they have for it. He can find the competition kit for it, but can’t find the GYTR power tuner. Do you know of anyone that has the power tuner for sale?

Any videos about the 2024 YZ250f?

Thanks

i had the neutral switch fault every wash , but otherwise i havent done anything to mine as yet other than oil/filters/susp fluid.

Could do with some graphics check S.K.D.A OUT & there's two sets of David pingree kits there the 23 nice blue or the, 24 50th anniversary white and red kit. ping said the Yamaha was too much power

Kris, i would love to see your thoughts on the CRF 450X and the WR 450. Some of us desert riders gravitate to these bikes.

the only hate comment ill say is im watching jett race his qualifier and it pisses me off Eli is out.....i wanted to see how those 2 do in outdoors

100 Hours same piston and rings no rebuild?

Kris - great video - thanks for doing these. Couple things: I see you’re back to stock triple clamps. What happened to the Ride Engineering 23.5 clamps? And did you ever try the 23.5 clamps on the ‘24 250F?? Secondly, on the FCP motor mounts, have you tried them on the ‘24 250F yet? If so same benefits?? Thanks

Same for the kx please!!!!

I miss my 23 had it for a few months and then some bum stole it from my garage

162 lb vet rider ,have read from 97mm to 108 mm sag! i ride in the north east loam and or deep sand! sugestions please!

How often do you change your engine oil?

Couldnt agree more on this bike being a soft feeling setup, especially the shock/ ride a 2023 yz450f inquired about a stiffer setup and was told the valving would handel a stiffer spring rate, and to stick with oem springs vs other types. How much nitrogen pressure do you run/ how often does it need to be checked?

Switching crank arm? Na just gonna go with another brand

I just dont understand how engine mounts can make a difference? they cant flex, and even if they could it would be like thousands of an inch of flex.. how would that make a difference? like explain the physics behind it.. or is it just placebo effect?

Are you still running the triple clamp spacer mod ?

8 hour clutch plates, new rod on an engine at 30 hours.....what a money pit. My 2022 Kawi kx450x is at 90 hours and all i have done is change the oil at 4-6 hours and fill the gas tank.

I would like to know if the rear fender gets folded and ran over by the rear wheel in US bikes also i live in Greece and every 23-24 yzf i know have the same issue

Hi, I wanted to ask you, in your opinion, which map makes the 2023 YZF450 easier and more usable for an amateur? do you have a reference map for this purpose? Thank you

Chris how much of a difference does moving the rear wheel back in the swing arm help with wheeling? I know you've talked about the swing arm pivot to rear wheel length before and how key it is to proper handling so I was wondering what your thoughts are on moving the rear wheel back without sacrificing to much turn in ability.

I’ve sent this to three Yamaha guys… Have you tried the longer swing arm?

Hi, when you got water in the kill/map switch causing the engine to sputter, did the computer throw a 33 diagnostic code?

Kris, how are you liking the anchor tape, seem durable? Are you using the “skate” material or “rubber” material?

Why does the brembo front brake need to be a specific year. I put a 22 ktm brembo master on a 23 yamaha nisin caliper, it worked great gave killer feel. Is there a specific reason for it being an 08 on both ?

Exelent! I just get the fmf slip on, do you cut the spark arrestor grill or leave it as stock.? Im from chile and here we dont need spark arrestor, but meaby the insert helps the Bike more Than remove it!!!! Cheers

What bars are you running?

How do you feel that yzf compares to the 24 ktm and the 25 with uodated frame?

I see a beta

dude give out more for ya house to avoid living in a desert getto hows your traffic outside

Do you know much about the guys over at mxtech suspension? I've watched a few of their videos and coty schock seems to rave about them

I can't imagine riding a yz with a sick front brake. I'd rather have nothing

Great video keefer

Listened to todays podcast about the W.E. Gotta change the RU-vid name to KeeferIncTested. Keep the brand consistent across platforms. 🙏🏻. Just changed bars on my new ktm from 827 (what I ran on my Yamaha) to an 839. That 1cm less wide makes such a difference, thanks so much!

Rad video. Thanks for the insight on the rod. I’m gonna be looking into this.

Thanks KK, very much appreciate all your content.....trusted adviser is a rare find these days'. My suspension was harsh as hell both front and rear (23 YZ450) had it revolved way stiffer and it's super plush now. (who knew lol) As for the power - i just can't come to terms with it, i'm whupped fast. It just wants to get there before i'm ready to get there lol which is fun for a few laps. I'm not getting a vortex - can u suggest what map from your site tames this beast best ?

What’s your height?
