Thank you for the exhaustive explanation. Other videos just blow hot air. This is a topic I find baffling. Okay, I'll pipe down.
I'm not quite done blowing off steam.
Are you sure you're not exhausted?
I think you should seek therapy, cause you got too much *emissional* baggage
Top tip: change the playback speed to 1.25x to counteract the plodding narration. That said, very interesting video!
Really works!
Yeah. I'm new to MotoGP and was wondering how this guy who should be fluent in front of the camera is bumbling his words so bad. This helped. Thanks.
@@DerickMasai I feel like he knows he's catering to an international audience, so he's intentionally speaking at a slowed-down pace through a technical monologue.
@@bramtahasoni That may be a possibility actually. I've never seen it done on air but I can't rule it out.
@@DerickMasai This is just how Simon is, he's not a natural speaker and has to think more about what he is discussing, but his knowledge in the sport is impressive and he's a blessing for the sport.
Simon is actually a treasure for the sport
I couldn't agree more, honestly.
He’s the best
I liked Dylan more but he isn't too bad either
Simon made it look like art
I personally can’t listen to him. I hate when people pause after every word they say. Gives me a headache.
Great info but guys editing the video, please, adjust the volume of the music accordingly and let us hear him better 😉
So great to see Simon not having to constantly adjust his mask
lol
Absolutely, so good to see his face.
UNDERRATED COMMENT LMFAO
I question why he was even wearing a mask ?? He's nearly always on his own and mostly outside
@@howhigh186 Probably a rule he has to obey in the paddock.
Simon is the David Attenborough of MotoGP
I love how Simon talks slow so that you can absolutely hear every word he's saying..what a legend..
1.5x Speed
PERFECT INDEED! He is truly a legend!
I enjoy and watch all the tech talks Simon does but the format in this video was very cool. You guys should do this with some other parts
Wild how much electronics and tech have changed in a relatively short amount of time...
I don't think any of us "normal" track day riders would actually be able to rider a motoGP bike. No matter have good you _think_ you might be... the crazy set up on these bikes - and the power and complexity of these machines is mind bending!
Not that many years ago, we had no aids.
Who won then? Rossi did... a lot.
Vale💌respect!
actually a motogp bike is very easy to use, for one used to normal bike (very light, fast to change direction, instant brake, transmit a lot of sensation to the pilot, ecc). The hard part is to compete and go to the limit. Imho if you are a normal track day rider, you can use a motogp with out any problem, ans stay at 15 seconds from a motogp rider
You might be surprised, I'd imagine they are quite a lot easier to ride than you think. Fagan on 44 teeth rode some BSB bikes recently and he said the 240hp superbike was a hell of a lot easier to ride than the superstock version.
From what I understand the hardest thing to get used to with a MotoGP bike are the tires and the brakes. According to Randy Mamola the way the brakes are on the modern GP bikes is simply in another universe.
Nice to see EXUP valves being used, same as YPVS in the 500 era 2 strokes. I am not sure who invented the first powervalve, but I think Yamaha was probably the first main stream manufacturer to really maximise it in the 1990. Giving the bike a lovely low rev range power boost.
YPVS effectively changed port timing (similar to variable valve timing in a 4 stroke) nothing to do with EXUP
yes you are correct, even though they are valves in Exhaust they work differently. The 2 stroke versions is nicely explained here.th-cam.com/video/4kERsqKC9Q4/w-d-xo.html
Incredible video. Amazing work. Keep up the good work
Excellent video.
Looking forward to seeing more
One of the best videos from MotoGP!!
thank you for the very informative video, I have learnt so much from it.
Wish there were longer videos like this🙏
I wouldn't understand it as well as I do if it wasn't for Simon's down to earth explanations 🙌👌
Thanks for the VID!!!
So interesting, this videos are great to see how much work and engineering in moto gp. Good to know.
All this just makes WSBK seem even more impressive given how close they can get on lap times
Espectacular saludos desde Colombia
Simon just keeps getting better at his job. Thank you!
The speech of the presenter is very pleasing in that it is very pleasant to perceive English by ear is not my strongest point and it is important for me ! Thanks . it's nice to watch and listen 👍
2021 M1 the sexiest ever... Love that minimalist exhaust
Yup, as for me. I like ducati's sound, but love yamaha's design.
Sorry Simon, I didn’t recognise you without your mask 😷
Excellent tech talk as usual - thanks for all the work you and the guys behind the camera put into these😎
Great topic, always wonder about them. Make another video on why the 2 pipes, explain why on the right side and one below the seat, explain why not both under the seat. Give contrast to SC Project versus Suzuki Akro versus Ducati versions, etc. And MotoGP pipes versus WSB pipes and SS ones.
To hear them live at full throttle few meters away from the tarmac is something mind blowing, gives you shivers thru the spine 😇 Can't compare it to the TV sound, obviously... Talking about the exhaust & engine noise combined, IMO Honda and Yamaha have the most ear friendly vanilla sound, less noisy then Ducati that growls a death metal baritone deep. Suzuki sounds quite an enjoyable high pitch soprano. Can't remember the Aprilia sound, but most of them all, I like the KTM, that delivers an outrageous metallic sound - just by hearing it you can almost see all the engine parts moving, pistons/valves/clutch/chain running, Q: Do you like music? A: I do, but not at 33/45 rpm but 15 000+ rpm heavy metal 🏁😁😇💪👂
I hope that in 2022 I will hear that beasts live on track in Austria or Hungary.
@@marioturkalj3126 Žalim, ali Mađarske nema u sezoni 2022 isto kao i nažalost nema Češke (Brno). Ako uspeš, preporućujem ti San Marino (Misano Adriatico).

Need to Go Back 2019, and see how much Moto GP video has developed. Forza moto gp
Great explanation Simon.
When I was 16 I put a micron pipe on my fizzy expecting the biz (from 50cc?). It resulted in lots of noise and little else, unless you wanted to annoy the neighbours. None the less I thought I was the bees knees. I'm glad to no longer be 16. 😆
In my humble opinion less chaotic intro and music would be better but thanks for the vids none the less 👍
Literally just cut straight to Simon that's what we all here for anyway
Fascinating!
Long live motorsports.
So kinda like my ole Buell XB12... What a man Erik Buell was, so ahead of his time.
Cool, so their cutting edge design is an exhaust brake from a diesel truck and some expensive metals that are fit for purpose.
I wanted to know about merge lengths, pipe lengths, pipe diameters, muffler design and what the perforated sheeting blocking half the exhaust tip is about.
The honeycomb grill is a gravel screen, quite literally for stopping big lumps getting into the pipe. The tip over switches don't cut in for a little bit in a crash, and with limited engines in a season, losing one to a piece of gravel wouldn't be ideal.
@@Minibull037 Thanks for that, good explanation, makes sense. But I can't help but wonder what is lost in flow to protect in the event of a ditch.
I've owned many bikes, and many exhausts... there's a reason I only buy Akra now -- their tech, performance and materials are unmatched.
simon is gold for motogp
simon's face! last time i watched a tech talk was when he was masked up the whole time.
is it the same thing with the 2 stroke exhaust valve? kawasaki with kips, yamaha with ypvs, honda with rc-valve, etc?
Stunning engineering
Like this format
Fantastic 💪💪💪
And for what reason they have a honey comb shape grill on the end of the exhaust pipe
To stop debris like rocks from the gravel trap to fall in and jam a valve or otherwise cause damage. Looks boss too.
@@mbpm6135 finally the answer haha thanks mate! yeah it looks boss!
Mendengar penjelasan dari om Simon Crafar, luar biasa sebuah knalpot untuk moto gp dari bahan titanium. Penuh dengan analisa dari setiap lekukan knalpotnya, gak salah juga akrapovic jadi produsen knalpotnya..
This felt more like an advertisement than a tech talk
Interesting, It will be a good idea for the company to develop something for moto electric. LOVE 💖💖💖
Are there street versions of these exhaust systems?
@motogp please put this video in your Moto GP explained playlist, thank you
So Simon, was hoping you'd touch on why the mesh exists on the outlet. Why do some use the mesh others don't? Why is used at all??
These racers are artists in their own right.
I thought Servo Valves were useless. My catalytic converter had a decat and it started rusting so i replaced it with a full set of akrapovic headers, the Servo motor/valve was obviously removed now it's straight pipe basically. But i haven't noticed anything bad when it comes to performance after i had it tuned.
Servo Valves are useful if you are a professional rider trying to get that last 0.100 seconds on the track. Not in the road making corner entries braking from far away very comfortably. Plus Servo Valves in road bikes are there to control the noise and emissions also.
It's not the same for roadbikes. On these their purpose is to eliminate noise at a specific moment where the bikes measured for the Euro standards etc.
The fool the systems.
Beautiful.
Pure sounds 🔥
They certainly refined the exhaust since the four strokes first hit the tracks. They sounded terrible but now they are music to the ears. F1 cars were the same when they changed engines.
Good video was great to see the bikes up close!
I raced a Supersport machine with titanium headers and Yoshi muffler it added instant horsepower in a class where bikes had to remain basically stock only suspension and exhaust mods allowed.
what is the purpose of the hex mesh?
That active exhaust probably costs more than my S1000RR
Simon is awesome! HOWEVER.... these are not the same exhaust systems offered to us, the mortal public! ):
I just took the exhaust servo out of my bike. Should I put it back on??
what i actuall want to know is, why some of them use under tail exhausts, isnt it bad to have weight so up high in the back?
Cak Simon tulung review Akra Lingga dong....
Is the valve invented by Yamaha? used to ride a FZR400RR in 1990 with EXUP system, was only 20 and it was the 2nd 400cc bike, 1st was FZ400, so not sure of the advantage
I wanna know why some exhaust has a metal mesh on it.
PRO LINER gmn ngab? Masuk moto gp ga?
Harkening back to the old days of two-strokes and their tuned expansion chambers.
I'm trying to get into MotoGP and have some questions regarding it. How many races per season? How many teams and riders per team? Any minor leagues or development levels? How are riders selected? How are points awarded? How is a race weekend like, that is, practice, qualifying and race? Specific rules and regulations? Popular stars, past or present? Thanks in advance.
Around 20 races per year (21 next year). Two riders per team, right now there are 11 teams if Im not mistaken. There are Moto3 and Moto2 (quite like F2 and F3, but Moto2 and 3 are world championships). Two FPs on friday and another 2 on saturday, followed by quali. Q1 for 12 slowest rider in combined FP time, Q2 for 10 fastest rider+2 fastest rider in Q1 (12 in total). Rossi is the most popular rider imo.
The gsx RR is a work of art.
Are these exhausts available for the public to buy?
Nice Simon
gsxrr's design is really cool
Almost sounds normal @ 1.25x speed, slowest presentation of the fastest 2 wheel machines lol.
The classic gixxer squid on a straight piped, stretched gsxr600 has left the chat lol
Great insite Mr c
I've said this last year, Akrapovic or any other exhaust maker doesn't have anything to do with MotoGP exhaust except sponsoring the team and placing a sticker on their bikes. Consider this, do you think any manufacturer would be willing to send Akrapovic their MotoGP prototype for building, testing and dyno tuning? Another example, when Honda was one of the first on the grid to have a seamless transmission even the Repsol crew were not allowed to view it. Honda had two or three HRC transmission engineers at the races and only they were allowed to touch it behind secrecy even from their own team.
Of course they do, it is drawings and models sent to Akrapovic and they send back the complete part. All those race teams are relatively small organizations, the cost of in-house prototype casting and machining is exponentially more expensive than outsourcing the 10 or 20 parts they need for the year
@@johnteahan2333 Except PokerPariah is absolutely right. None of these GP teams whether small or big organizations matter in these context. The bikes are all essentially manufacturer "factory" prototypes anyway. All the exhausts are in house units, how else would they go through multiple variations to test on their own dynos. And don't even joke about the cost of prototype casting and machining of parts. This is MotoGP not some national championship. The manufacturers are routinely casting their own prototype frames/swingarms/parts/ multiple times a year to get even the last tenth or that extra bit of stability/braking/acceleration advantage. It's just sponsored stickers on bike manufacturer exhausts. No matter which sponsor on Honda RCV, Arrow (LCR) or SC (Repsol), its the same damn exhaust HRC makes. The look and welds always gives it away. Same goes for Yamaha or any other team for that matter.
@@johnteahan2333 with this mentality and critical thinking ability, take a good look in the mirror and see why you’re so low on the corporate ladder.
as someone who worked there....yes they do. Dont be silly. And putting Akrapovic in the same group as "any other exhaust maker" is just wow. Now pls hit me up with the: "that's why you're so low on corporate ladder" for some comedy relief.
@@matejskerjanc7703 Prove it.
Why are some pipes open at the end like on the Ducati and others have the hole punched screen covering them like most of the other bikes?
To prevent any gravel
they're actually there to prevent excessive flames from the exhaust when off the throttle
super Slovenia
Exhaust Look, Sound, Materials Used Everything is Just Fabulous 👌🏼👌🏼
Nyimak mbah
Somebody...who came from their previous carrier...can tell the passionated story...about their love!!
No mask makes me smile. Love this!
Simon 💌 Respect!
@@____________________ok 🤣
For next videos,, please Indonesian subtitle
so why it has two outlet exhaust instead of one?
I would be surprised if the manifolds are not 3d printed Inconel tbh.
Why two of the V engines (Ducati and Aprilia) don't have this kind of mesh at the end of the exahust, whereas all the inline 4 + Honda (V4) feature it? Anybody knows?
They like gravel down the exhaust more than the other brands.
@@joepi5 hahaha Pol Espargaró approves
I love akrapovic
Exhuast for sc project plss
My Super Duke has this type of valve on its exhaust as well. I thought it was only to reduce noise to pass regulations. But I doubt it fulfills the same function as in MotoGP.
Μy 2003 gixxer 1000 has an exhaust valve also.But now i wonder why every aftermarket exhaust doesn't have it and why even when they put only an aftermarket can they dissable the exhaust valve..
It does help with low rev power delivery, and it does help a little with braking, but for streetriding these things aren't anywhere near as important as in racing.
Why do they put those honey comb like cover in the end of exhaust? Why not just open?
So it's an exhaust servo, that literally everyone rips off their bikes when installing an aftermarket exhaust lol
why F1 sticker on motogp bike? 2:29
sponsors
sponsors
sounds like he has a speech coach
“variable engine intakes 🤏”
Akrapovic Price just went up after this ahahah
I use RACEFIT exhaust on my Repsol 1000RR and its loud ASF my neighbors hate me
A bit of info about Inconel en.wikipedia.org/wiki/Inconel and places it has been used en.wikipedia.org/wiki/North_American_X-15
Is Akrapovic the only exhaust manufactory in MotoGP?
Sc project for repsol honda and Arrow for lcr honda
@@edwardjoseph1509 Awesome, thanks!
From what I heard yes, teams which have a different exhaust brand (like Honda with SC-Project) apparently still take the exhaust from Akrapovic, but due to the sponsor, but on a different decal.
And Sakura for Dovi's M1
Can anyone explain to me why among all other clearly visible motorcycle parts, the exhausts are placed differently on MOTOGP bikes? What effect does this have on the bike's performance?
Because these bikes other than 2 wheels and maybe a certain displacement.. Have literally anything in common with a production bike. As Simon says, Akroprovic literally have to fit these exhaust in the permitted space provided by the manufacturer.. (Why each MotoGP bike is different)
On top of this space, if each 4 cylinder engines exhaust is split into 2x 2-into-1 systems... you would then assume each of these will need to have an equal length from exhaust port, to where it merges into each exhaust. then generally to its tip.
I don't know why he's talking so extremely slow, but 1.25 speed on the video makes a lot of sense 😂
Ngl it was kinda relaxing, very David Attenborough 😂
And there's an insight to why these bikes cost so much to make. 5 axis machine to cut exhaust parts? Crazy
Sound comparison, pleeease
Meanwhile our city doesnt allow aftermarket exhausts louder than 80db. 🤡🤡🤡🤡🤡 Absolute clowns.
Basically yamaha EXUP today. fantastic
Guess what? The pipe designed by the vehicle manufacturer, Akra just slapped their name on it.
