It all starts with the mechanic in my opinion, they are the riders better half and need way more recognition.

Duff better move up to 450 when Heiden does couldn’t imagine him having a different mechanic. Duff is the best.

I'd like to CLAIM that bike

Really good interview. Finally an interviewer who actually knows what he's talking about and asks good questions lol

DUFF always seems like the nicest guy .

Should run those colors every race!

This was rad to see love deegs/duffe combo you can tell he really admires the kids work ethic and heart he has in the sport. I've seen comment after comment keep these two together and I totally agree he knows deegan is a future champ is going to win a lot I think they are a remarkable team and look forward to watching them this summer

Takes it down to the frame every Sunday. That’s so cool.

The only gem I took from this is that Eli hopped on Haydens bike in Colorado and I'm sad we will never get to see that

Thinking of claiming it ....🤔

My buddy Andrew Bauer from MN, all around good dude and mechanic tried like hell to get into the pro pits. He did it by wrenching for a bed and meals for mid level privateers. I think he may have worked on Davi Millsaps practice bikes for a bit. It is easy enough to get into the industry getting to where Duffe is though is incredibly difficult. Well done sir!

Duff and Haiden are one hell of a team that's for sure!

Duff is perfect for Deegs hope he’s on his bike for a long time

He couldn’t have said it better and he is 100% right Haiden is a great person and has really worked hard to get where he is and you can never buy the talent and skills he has and he is the Future and I’m so proud and happy for him and his Family and his Team and again I love that 50th anniversary Yamaha also Thank you guys for sharing this amazing video and his mechanic is awesome and he is to a great person and him and Haiden are like McGrath and Skip was back in the 90s and I’m super proud of them and also always got to Thank his Dad Brian as well for the way he raised him and showing him the path to success and I want to wish them all the best always #TheDeegans #HaidenDeegan #BrianDeegan #RacerX @Duffe

Just put Haiden in thumbnail and even the haters will click and give you views 🤣

Great team getting it done. Lets keep the momentum.

Red line is set 'To the moon and back'

Gotta love duffe!

Duff seems like such a cool dude, and truly has Haidens back.

Duffe the man! Lets see Duffe geared up and puttin down some hot laps 🤘

Duff is my guy so humble

561 to 303...shout out for knowing the difference between Lakewood and Denver...palm beach represent

The bikes are so damn impressive. can smell the race fuel from here.

please more vids like this

SUPERGOOD Mechanic Haiden!!

Goat Interview! Badass mechanic! sick bike!

Brent is the man! Deegs will be a 3x SuperMotocross champ before he moves up to 450.

That was a really cool video! More of these!!

The duff man ...o yeah... duff baby it gets the job done

best mechanics of star racing really friendly interview !

Awesome! Deegan is the modern day McGrath. I love it. I always loved McGrath and deegan has the same go get it attitude.

More bike checks, these are cool!

Yamaha put out probably the trickest bike ever

Please keep these videos coming !!!

great interview

Is an altitude motor the same as a Deegans Loretta Lynns amatuer motor?

Haiden wouldn’t be haiden without duffe.duffe doesn’t want the attention but he makes sure that bike and haiden are ready come Saturday…duffe is one of the coolest dudes you’ll ever meet…matter fact,the Yamaha team dudes are pretty good fellas

Haiden has a badass bike. That purple back ground looks good on that bike. I bet next year he’ll have it again. I believe in him that he can take everyone to school.👍🙏💯✌️🤙✊😎💪🫡🇺🇸

The same bike he raced at Loretta Lynn's.

Great video.duff is great mechanic and superb for haiden

Looks like the perfect claim.

Let’s go duff!!

Yamaha for life

Low key down to earth Humble but will be at your trailer crying if you bump him!🤣

Great video, great mechanic.

Same engine mods Deeg was running at Loretta Lynn's Amateur National's last year when that issue with the bike claim happened...???

Great video

Duff n deegs gonna win mx and smx

Letttssss goooooo, Duf!!!!@@

Duff is the man

I love this bike Dangerboy 💯

The ccu is the secret that and a 450 air intake it's all in the ignition timing they run a vortex guaranteed

Love the look

I love it

We want more duffe

That was interesting. He wouldn't tell us the off set, the gearing, what the exhaust is, what's been done to the motor, rev limit, the air box modifications and fuel tank size. Air forks for supercross and springs for motocross. That's all I got out of it.

Those them Loretta engines? 😂😂😂😂😂😂

Awesome Duffe38 & Dangerboy the best Combo

That bike is beautiful

Is this bike for sale? Asking for a friend..

I have a good feeling of the extent of work they got in this bike. I mean obviously they will want to change gearing it’s not a secret, the engines being built specifically for the factory teams are no more then custom porting, custom pistons, custom lightened crankshafts/rods, cryogenic treated transmission. All parts most likely has been micro polished or Nickle plated such as the piston for longevity hince why he says they are reliable parts in the engines. Ceramic bearings. I’ve build bikes with them before super expensive for maybe 500rpm difference. Just from testing purposes it’s all I’ve seen. Now with the clutch I’m curious about. But I don’t think it’s all that factory like they make it out to be. Maybe if they designed a custom bore piston that is within the rules which what pro factory team these days especially on the amateur level follows them??? The camshafts are custom grind cams from guys that know how to do the math with making camshafts like some of the guys I’ve used. There’s a few so no names in particular unless you want to ask… The valves are also possibly custom machines valves. Porting they have to test on a flow bench , that is nothing new. I do that. But also epoxy on the ceiling of the intake port to force induction straight into the combustion chamber. Too much volume of air because induced in the port could trap air and make the bike not run as good. Sometimes more isn’t always better. Custom valve spring rates for higher over revving… why you think haiden is always launching like a rocket once the gate drops vs the other riders??? Higher over rev engine with lightened crankshafts, and “factory” transmission. Custom ignition system. Custom fuel system. Custom chassis. Custom intake/exhaust systems. (Proven at dyno.) Sure they run dual injector like everyone else. Also when they talked about clutch, I have used different springs before from other applications and the clutch felt soft or stiff. I had experienced this before just seeing I Fn it was possible. But the same applies to the valves. Softer springs will just allow valves to open/close faster, thus increasing over rev. Anybody can build a factory race bike but get real who has $50k laying around to build one. And I know it cost way more than that to research and develop. Then make multiple race bikes because they want more riders now to win more championships. But yea I mean engine alone in these race bikes are probably $25k in research and development. The rest is testing the ignition system, dyno, suspension etc. If it were me, electric water pump and external oil cooler that can be welded underneath the radiator. Or a custom radiator with it built in. And a catch can welded on frame. I know it will have some Blow by because thing is revving so high. Oh also forgot to mention, they have throttle body modifications and custom machines butterfly valves. So like he said, they like to breathe. That’s way to make easy power…. I’m building a race bike to be competitive on the “factory” level it’s more of an experiment and working with my resources but seeing how far it can go. Maybe 60ish horsepower for a 2024 yz250f. Maybe little more than that. Without it blowing up lol

Just don’t try to claim it.

Never knew Duff was tall as Kris..

Pos just like his dad we all remember the 17,000 bike deal for his bike

🐝🏁 Video 👍

I have a 24 250f and I’m looking to enlarge the tank. What tank are they using? How much gas does it hold? I’m seeing a 2.8 but that’s too big I think. Any help would be appreciated 🙂

Haiden is Brian Deegans kid!!, and he does not have any tattoo's!!!!!!!!??? That kid is serious. I peg him tough to beat for his entire career. I like what he says. He is a confident kid, and I love to see it. :)

Can someone buy Yamaha and cut the holes in the air filter top or is that for a modified engine only?

It’s how he talks on the podium that makes people think that

🔥🔥🔥

The bed bug comments are exactly how I thought they'd be

I would be so fast on this bike! At 64 years old, those guys better be glad I'm not out there with them. I would surely cause them to crash because I would be like a road block when they came up on me. But boy on the straightaways I would be screwing it on! lol

So there’s a clutch and other things that we can’t get. So explain again why we have the production rule

🎙️ I couldn't have done it without MMI on my resume😅

Yamaha is the best brand for dirt bike

Star is the American factory Yamaha

nice bike i like it

Nice bike i'll give you 15k for it

hes won the. last 3 races too

Remember what the Deegans and Star Yamaha did to Brennan. Disgusting. “Special” bike, right. Racing a pro motor and threatening people. 👍good job.

He said the deegans are humble 😂😂

Thanks for the time gentelman🏁🏁🏆✨️🏋‍♂️✨️🏋‍♂️great BIKE ,,WHAT A MANCHILD on that machine😂🎉🎉😂🏋‍♂️🙌🤳🌟

Now he has to figure out how to make a red plate cool

careful, someone might claim it and you'll have to get daddy

"Off track edition"?

Where can we get those rims? So sick

Most important person on any team is the person responsible for the bike! There are a few out there, but most fast riders are shit mechanics... I repeat MOST of them. So It doesn't matter how amazing your rider is... if the bike dnf's. Very overlooked in my opinion. Props to all the mechanics out there in the trenches!

Look how far back his bars are over the top of the forks

0:36 Wait, why would this not be a factory bike?

Kris has some good taste in footwear 👌

Dam where's 14k when you need it

@Brent there is a career in politics when you done with this 🤣

Whats the horse power of a bike like that? 40 horses

Second injector wink wink

Engine is stock my ass 🤣 watching the star bikes go up big gulp and then watching regular 250f go up it there’s zero chance it’s stock motor.

nobody trying to buy his bike this year i bet ya.

Had Duff Sweatin’😅 Dumb Secrets.

Please don’t tell me pink on dirt bikes is coming back? Ugh, I lived the 90s, no more pink

Why wasn't they so open about his loretta lynn bike a few years ago... All kinds of shady nonsense went down at that amateur race involving an illegal bike and this exact team !!! No one else caused any of that except Yamaha and this crew.... Facts are facts , the kid never got the bike and the whole situation was a clown show.

Humble, u need to look up the definition of Humble 😅
