Akrapovic has announced this in their web site:

http://az79640.vo.msecnd.net/akrapovicbppmultimedia/15a11acd0d7d43a4b88dc5fb128b32be.pdf

Note that torque is Nm, not lb ft.
It looks like it is measured at the rear wheel but it is somehow calculated or corrected so it could be close to engine power. You can compare e.g. Dyno curves from other bikes BMW S1000RR or Ducati Panigale. Then H2 numbers are quite disappointing. I expected a lot more torque. Also I wonder why power drops in the end like that. Might be throttle opening is restricted. If that is the case hopefully there will come a solution available.

Akra slipon wight reduction 5,6 kg and power at max +4 hp .

Akrapovi?

 

[garth285]

Finally a dyno sheet of the H2!!!!

This is really good news, do you see where the power is dropping off!!! 10,800rpm

This means they are most likely just killing timing/boost/fuel a ECU flash will for sure take care of that!

If the bike makes say 25hp per 1,000 rpm your looking at close to 275hp no problem.

AWESOME SAUCE

Cheers! +4 hp, for HOW MUCH?

 

[Mikkoyli]

I ordered my Akrapovic slipon for 1300 Eur (about 1540 USD). I ordered it because of the looks and weight saving. Original muffler is too big. Akra is not beautiful but it suits the bike, H2 is not pretty but it is different. I think standard looks muffler like Yoshimura, Remus etc. would look boring in such a special bike. Akra for sure is new generation looking muffler. Noisekiller can also be taken off if I want more sound but it is legal when needed (with dB killer). Weight saving I expected more, original muffler is not so heavy as I thought.

Yes I would be very happy already with 250 hp. Hopefully some tuner or even Kawasaki would sell ECU flash or dongle like KTMs use to have. I wonder how much camshafts are different and if they are restricting, too. Because of emissions they may have much less overlap.

385 USD/HP...

Using stock figures the H2 itself costs $125/HP

 

[Mikkoyli]

Yes I believe this is how we will get the bike and it is quite a disappointment. Akrapovic is normally realistic with their curves. Have you seen any better curve? This is also what Kawasaki has announced, they can not lie more than maybe 10% inaccuracy. At least in Europe it affects insurance, etc. liabilities so that was not a surprise. However, I expected much more torque at low rpms which would give good performance or much better than typically others do. That curve is nothing beyond belief or offering new level of acceleration.
1299 Panigale beats stock H2 in every area.

Only hope is that restrictions can be removed.

Sorry...I deleted my post.Kind of 'shocked' a bit with that dyno sheet.I don't have any others...I'm sure they're around somewhere.All the new sportbikes are surpassing these numbers....Garth thinks it's good news...apparently he sees something in there that can be adjusted...I hope so...I'm not normally a HP freak or anything...but 197 from a SC 1000 isn't anything special...I could have bought a 10R and had these numbers.

Surely it's got to be able to do better than that...it just HAS to.Right?You know...once guys start getting these and dynoing them...the guys still waiting are gonna see these numbers...if they stay like this...I think there's gonna be a glut of(cancelled) unsold finished bikes sitting on showrooms OR at the factory.Surely Kawasaki knows this...

 

[Turtle1000]

I REALLY doubt they'd post a fake dyno printout..... If they did it would be making more hp not less, that makes no sense imo. Garth is right. This thing is every bit as restricted as my 10r just like I predicted.. It dives at 11k rpms just like my 10r I have attached a video that discusses de restricting the 10r by guhl and Brock's on the vista 10r it shows the dyno before and after derestriction.

https://m.youtube.com/watch?v=tjX_vNgRdek

It does suck that you guys will have to rip apart your ridiculously valuable bike, I have to rip apart my expensive bike as well, expensive being relative.. I thought I got a killer deal at 11850 but they're out there for 10600, 10500 and 10000!!! Man that's cheap for a nasty bike but anyways yeah after ripping that ecu out mailing it off it will be insane. It's insane now but wait till those secondary throttle plates open wide at low rpm instead of higher rpms and stay open till redline... Never mind gettin rid of the speed limiter.. And the extra 500 rpms the flash will give you..

I am not a fan of the exhaust but I would consider keepingit if the akra is too loud. All of these bikes are cop magnets and one with the kind of cream this thinfgs gonna have top end once flashed is insane. LAF for those unfamiliar it means loud as f. My bike without flash and with stock exhaust and cat and the exhaust servo working and it's still loud. This reminds me that I have for a long time thought the exhaust servo slams shut in upper rpms for noise control ( RG mentions this in his 10r early release videos) but on another site I saw the computer representation of what the exh. Valve does and it appeared to stay open till redline. It did its job staying shut in lower rpm to build tq. If anyone knows what the 10r ex servo does at high rpm I'd appreciate the input as I am debating whether to have it disabled in my flash. I didn't wanna open a thread for that and it's not an h2..must your h2 has the servo so you need to consider as well that's why I posted it here first.

As the video above shows the 10r has 165hp before derestriction Iand it ends up with 182 hp with the eu map and flash The h2 is 190ish totally restricted. 200ish with pipe... I'd think 215 maybe 220 is possible with stock exhaust and 225 maybe 230 with pipe, now if they make a full exhaust that still makes it quiet enough for the street but gets rid of the cat then you'd be upping it some more, not a ton but 5 or so I'd guess I'm not exactly sure the gains associated with the cat removal so that's a crap shoot but either way with the lost weight it would be a freaking rocket. My 10r is insane with no flash, I heard with flash it is a rocket so I can only imagine. I need to figure out the hp per lb ratio for them both as that is what tells the tale

And silver no 10r stock has these numbers... Even the euro spec ones are 10hp down. I'm not sure what you guys expected. I'm with Garth I'd be happy, like I said above just rip out the ecu and send it off, if this is somehow impossible than I'd be disappointed. But until then your gonna see that little line keep rising till 13.5 not have it pointing down... I wouldn't worry

AWESOME SAUCE

I am slightly more conservative on final unrestricted stock no pipe number. Im thinking this thing is more like 17 or 18 hp per 1k rpm. It will push for about 2k more rpm so that puts it at 225 by that number. Which is what I heard it was like 4 months ago. Keep in mind this is almost certainly a usa bike. If it's not, then worry..

 

[SilverbirdH2]

"It does suck that you guys will have to rip apart your ridiculously valuable bike"...well if it's only a matter of ECU tweaking...I'm okay with that....that's nothin.I always have my killer 14 to ride while I wait

"if this is somehow impossible than I'd be disappointed"...looks very doable in the service manual...now I'm okay againThanks for your encouraging words....seriously.

And I had no idea what the 10R was making...thanks for that vid...very nice.

You shouldn't have to perform surgery to get what you paid for, I'm in the same boat and it pisses me off. It sound cool now sitting at home thinking about it but it won't be so cool when your risking a scratch, wasting riding time or just your time in general. It's not Kawi fault either... It's big brother for treating to fine if they don't neuter their bikes. But for the big picture hook that biotch up to a pc throw it back in bike and see what it really has

 

[ZX-14R_stealthrider]

From a marketing perspective (likely in consultation with Kawasaki), I am not at all surprised that Akrapovic didn't release the Technical Data and Performance Graph on its Slip-on for the H2 before the Closing Date for H2 Ordering in the U.S. and Canada.

Our hopes that Kawasaki was under reporting the H2's actual power stats evidently were unfounded.

Even with the "possible" likelihood of an ECU flash, I would certainly have reconsidered ordering an H2 for $27,500 MSRP (CDN) with these numbers.

I would expect that Yamaha and BMW now have big smiles on their corporate faces. >

 

[GoFaster]

Doesn't surprise me that it's restricted (a lot) ... they have to keep the Euro regulators and insurance companies happy ... doesn't surprise me that Kawasaki was cagey with the performance specs knowing how much it's restricted.

A centrifugal supercharger is only really effective at higher revs, so that's not a surprise either.

I am quite sure that getting more out of it will end up just being a reflash away.

They never promised you anything. Show me where it says you were getting more than 200 HP. Why don't you stop complaining? I'd be perfectly happy with 197 HP because that's all I care about.

(I'm not really giving you sh*t, I'm just showing you what my world has been like here for weeks)

So what you're saying is; the bike really only makes 200HP, but Kawasaki hid the fact in order to get you to buy their bike? Kinda like leading you to believe it was a one year bike with a limited order window then turning around and selling bikes to anyone, anytime and with no end to production in the foreseeable future? I'm shocked (insert sarcasm here).

The H2 is rapidly becoming the biggest bamboozle in the history of 2 wheeled motorsports.

garth....Let's say around 265-275hp, What would you think top end speed would be? There will be an electronic restrictor on the H2 in the USA.

Clutch and gearing would need upgrades?

 

[Turtle1000]

H2r --
All I was saying is you shouldn't have to flash your bikes to get the most power out of them. It should just come that way. Not sure what you were saying.

All of the early reports put the bike around 225 rwhp for the euro spec, or in other words a non us bike, which will need the flash to reach that. Imo with that pipe and after the flash the bike will produce 230. I think 275 is unrealistic seeing as how the R made 292 or 296 I can't remember. I doubt a flash and pipe will gain 85 hp but I could be wrong, I just don't see it getting that close to the Rs hp. I'm assuming there's a big difference in boost psi between the 2 bikes.

Hayabusa's running about 260hp can go about 220-230mph depending on setup. This bike is lighter but not sure on the aero's

If you can get 250hp outta this bike and it weighing 50lbs lighter than a busa give or take I'm sure you can see speeds that fast. You can do those speeds on a stock clutch with good springs and gearing yeah would probably have to be changed.
