YAMAHA R1 | FULL AKRAPOVIC EVO EXHAUST on the DYNO 

a dyno vid without the jhs boys feels wrong

The Management is walking past the TV whilst the music is playing for the slow-mo wind shots and she asks, "Is this 44 Teeth? ('Yes') You can tell without looking". Successful branding complete

The chain sounded as if it were misaligned when the run started, so it was a tight spot, thanks for that. Being an engineer, I used to align the rear wheel by spinning it until it made the least noise. The bike is stunning even at 64 now it's got me looking at 2015 R1 M's. Some say adrenalin keeps one young (ish) so at 64 if I relieve myself of this mortal coil in a cartwheeling fireball, I don't think I'm going to miss anything exciting.

That intro was top tier 😎👌🏻

I really enjoy this R1 series and the collaboration with crescent, it's great content.

2 boys 1 pipe

Hope you’re on the mend Al, looked like a good knock yesterday.

Might aswell go full 44teeth if the bike needs colour, and get track fairings featuring some pink flamingos and flourecent burgers to match yous pairs leathers 🔥

That Arrow slip on was a bargain.

Hope Al is OK after yesterday's crash

Those power graph curves look stunning to me, no dips or spikes, I would love to feel the power delivery. Chris, I look forward to you telling us....

As an MT-10 rider this makes me smile.

Good to see my old 2002 Blade is still 'ok' Dyno graph wise. It runs exacly 100 Hp @ 6K, this yamaha at 7K. But mine tops at 145Hp @ 10750 rpm, limiter is at 11.4 or so. It is an oldy, but Cool to see it is not completely obsolete. Love the crossplane sound, must be a beast.

Is Crescent sponsoring this build? 3k for the exhaust plus labour to install it, then the dyno time, all for a bit less weight and no extra HP?

Those wheels for the black and gold look will be exquisite

Sexual dark chocolate in the black paint job, but I understand it needs to POP for video. And to continue the choco theme, it's going to look like a bastard Ferrero Rocher with those wheels. You're spoiling us.

10/10 for the thumbnail 👌

Modding bikes way to go,, putting marchesini wheels on my K6GSXR tomorrow,, great stuff ☘️😁 from northern Ireland

That noise does make me miss my 2020 R1 with this exact pipe. Enjoy that symphony!

Those wheels look sooo trick! I recently had the same wonderful experience of fitting a brand new full Akra system to my 18 blade 😍🔥

the sniff on the fresh tire was spot on

Wow! I never knew Sue Perkins was so passionate about an R1 😍

That bike is looking awesome!!

Those wheels about to look fabulous on the bike. Looking forward to it

The exhaust looks and sounds brilliant

evolution line, longer muffler with that streamline shape always looks good on every modern superbike. arrow pista for example. not too noisy but still sounds awesome.

3k on an exhaust for slightly less dyno HP than before . how much of a difference in HP do you think this new system will make on a cool day? worth the investment bearing in mind you are running it in spain ?

Looks sick!! 🔥Love the Matte Black and Gold combo! Enjoy!! Look forward to seeing the next one!

This video got me well excited. I'm going to Crescent on Saturday to flash the ECU on my black MT-10 with a full Akra system. Can't wait! 😁 Love the way the R1 looks now 😍 Team Yamaha woohoo!

I just had to explain to my wife why I laughing so hard at this. She looked at me like I was sort of prat! 😮😂

Bike and wheels are glorious!

Oh how I was longing to see those slick shod Dymags on the bike.......😢

The look of that bike with the gold dy mag wheels is going to do things to me...

A white front wheel and that yellow on the 4:02 exhaust on the back wheel with the black body work would look pretty sick

Hands down the best looking and sounding Exhaust system you can get for this bike. There is a reason why WSBK teams use that too and not Arrow or SC project..

Loving the R1 build series, looking forward to Chrissy Wissy not crashing it at the track.

Great vid as always boys...Al hope you are recovering well after Sundays off...

Good to finally get to see Arthur the legend ! R1 is sex ❤

It still blows my mind that a place in Slovenia makes the best exhausts.

you should have dynoed with the Arrow when you got there 🤷🏻‍♂

the sound is wicked - I love it!!!

That intro exhaust sounds so tasty!!

Great video Chris, please tell us if you plan to visit Snetterton for a track day, would be great to meet you all. The R1 is looking awesome!!!!!!!!!!!!!!!

That Intro was gold 🥇

If you want an idea for a colour scheme, the light grey/red reflections at the bottom of the bike @3.44 minutes look pretty cool to have as a colour scheme throughout the black paintwork, kind of like the old West f1 paint scheme McLaren had.

Wow even though it sounds better it just shows how well the stock headers perform. Any real power gains you'll probably have to crack the engine adding cams, cranks, pistons, etc.

That is an absolutely beautiful R1 !!! I'm just curious where did you get the full Akra system with the laser etched logo ? I'm from the US and could not find that anywhere.Cant wait to see vids of you guys on track with that monster !!! Thank you n keep the amazing vids coming !!! 🔥🔥🔥

I was chatting to Chris at Loomies Sunday.. I was showing him my Hypermotard... I'm sure he was pulling that face... 😆

Good stuff - let it keep coming 🙂

Well; the viewers could see the obvious difference between Chris' massive air-intake and that Al's was suffering because his cheeks were too tight. Heyo: How about a few van-video clips of the drive down or; we love you guys on a boat-ride too. For those of us in the colonies and provinces; this never gets old.

That bike is a beauty with the decals in black; stealth out that lever though please!

Very unlucky yesterday Al, hope your not to sore

Bikes done more miles on the dyno than the track

Am I the only one who got bricked hearing and seeing that sexy system ?😎

Christopher Charles, i would highly recommend that you splash out on the carbon race fairings for more rigidity because those race fairings you have on there look like they are trying to peel off the bike with the dyno air blower giving them a blow job, so god knows what they are flapping like at 180+ mph in the real world. She's looking nice though.

Love the sound of it ! Looks great too! Nice work boys! It is a little dark though , looks like a Wintertest zx10 rr ! Stay safe ! Pawlak

Well... that seems like £3k plus labour pissed up the wall 😂😂😂

is that the face you pulled at thruxton when you were tumbling al 🤣 only jokin xxx

I have a mt10 and love the sound of that engine if the arrow exhaust and link pipe are just sitting about I have a home for them lol

I’m going to say rad can stay put if only headers. Loads of clearance by the looks of things. Oil cooler will need to come off on one side though

best handling sportbike in the market...

Beautiful wheels nige. Got to have some bling ✨️👌🏼 in your life.. cant wait to see them on ❤.

@1:54 TVR casually sitting in the back

It's so gorgeous

Intro montage 12 out of 10 style points 😀

Those gold wheels 😳🤯

Is it only me that was looking at the sexy silver golf mk5 😍😋

Love it Chris, keep up the great work ❤

Quality video but it needs the "Hawk Tuah" girl in it surely?

That intro lmao

With the stock end can being quite short, if you just add a decat it makes it pretty loud, I reckon louder than this full system. Not that I want an obnoxiously bike but just saying. Decat are pretty common used on ebay but a new one is around £200 vs £3000.

Absolutely fukn beautiful bike, and it sounds amazing!!!! Get them new wheels on an its gonna be 😲Ohhhh PERFECT!!!!!🍻🤙🏼🤙🏼

Sounds beautiful that Nige

That's a spicy thumbnail. 😂😂

RONCO INSANO E PURO, SENSACIONAL 🔥🚀

The bike looks and sounds amazing. Wheres boothy hiding out. Is he not allowed to play with you lot anymore 😂

Sounds proper good. Wonder how much db this would do, I don't think I could run this on a circuit here with or without baffle, gotta love them db limits.

id love to see the SAE smoothing numbers

Was hoping to see James, great vid regardless

@14:34 Black 'n gold? ... nice ;)

Great video! Love the intro

This R1 is lovely!! Do you plan some fancy buttons on clipons instead of stock? Like race switches typically?

God I love 44teeth

Paint it white and add the pink speed blocks so it matches the BBB yzf750

Understandable as it is clearly balls amount of power to have 204.7 hp instead of 206 hp at the rear wheel. Imagine having only 170 hp at the rear wheel; then you'd almost have to flinstone your way across the track

First 10 seconds was good enough

Chris in the cooling fan looked like Wallace (and Gromit)

My favourite channel so far 😂🎉😅

I ran to go grab my headphones after reading the video title

So when does Fagan get to ride/crash it?

Looks and sounds fantastic 👍🏻

Those gold wheels 🥰

Did you specify which sticker it came with? Don't these come with the standard red sticker? I am planning on putting this on my R1M and I think the one you've used here will look really good on mine as well. Love the upgrades! Thanks for inspiring us :)

Gb racing fin for rear chain finish it off 👌well mint👊👊👊✊✊✊✊✊✊

Sounds awesome 👍🏻👍🏻👍🏻

Shame they didn't just do a quick baseline run before swapping the pipes. That would have given actual power gains, same dyno and same day even if it is a couple of hours apart.

Hi Chriss have you found the magic geometry number yet for the swingarm? Im gonna do the same to my swingarm and get a little bit more length, what sprocket size do you run front/back? Love those wheels, are they much lighter than oem wheels?

Fagans face in the thumbnail 😂

Three grand with very little gain. Ouch.
