The HP4 is going to pull more on the dyno than a S1000RR, due to the wheels being lighter and the exhaust giving it a few in midrange. I would guess we'll see a few more on top due to the lighter wheels.
The Akrapovic website shows the dyno between stock and the catted exhaust these are coming with as well. It shows 4hp up top with greater gains in the midrange. Coupled with what has already been mentioned, it should make more power. Maybe BMW is helping us from an insurance standpoint or just wants to be sneaky by underrating it.
I qualified for an AMA superbike grid on a bone stock 2012. Didnt even have any fuel management. The bike is already plenty fast. It'll make that R1 of yours feel like a pw 50.
Edit: I did have a full exhaust and changed my gearing.
btw H2 - I know of more than a few guys that have installed a full system and not bothered with any fuel management changes. The bikes run fine, maybe not as well as they could with a custom map on a PCV, but well enough for the owners to be satisfied. Our local dealer even endorses this activity.
The engines are exactly the same between the std and hp4. With the addition of a better flowing exhaust on the hp4 it will show more hp on a Dyno over a std s1000 until you install a aftermarket exhaust on the std. model. You pay extra money for suspension , paint and wheels. Why do some people think it's a whole re designed model?..lol
9. Stage 1, 2 and 3 race kits: So, you want to go racing? BMW offers three track-only levels of performance for the HP4 that are likely the best bang for your buck for aftermarket parts and support. All stages offer an increase in horsepower—201, 205 (AMA Pro SuperBike) and 212 (World Superbike)—along with the ability to fine-tune DDC, DTC, ABS, Launch Control and engine management corner-by-corner on the track. That should be enough to make your head spin! Good thing you also get access to BMW’s race-support staff to help with setup.

The abundance of moto press reviews by current and former pro racers doesn't do it for ya?
The only negative comment I've read was Chris Ulrich's (Roadracing & Motorcycle Technology) comment about front rebound/damping tuning limitations which can be resolved with the " optional front fork potentiometer which plugs into the wiring harness allowing the circuits to be separated."
In spite of this issue, his conclusion: "....the best of the current crop of sportbikes on the market.
His review is the most neutral, balanced, least "gushy" review I've seen yet.
I'll be honest with you...I'm excited about reading ANY ride reviews from anyone whether they're Journalists, Racers or us...Owners who have bought one.
I love riding my 2011 S1RR because it is an awesome sportsbike, but I am like a little girl at Christmas when thinking about getting my HP4!
It just sucks that my bike isn't arriving in Australia until Dec 27th.
In the mean time ANYONE who gets theirs PLEASE post ride reviews so we can all share your experience.
Wattsy, When did u put down ur deposit? I put mine like 2 weeks ago at southbank bmw melbourne. said minimum 3 months waiting. My god.... I want some nice christmas gift too but guess it is now a CNY gift or even easter lol

J, apparently I was the 3rd person to put a deposit down in Australia...I'm still trying to find out who the other two were cos I want to stalk them given I put my deposit down within an hour of the bike going on sale.
Did notice as the dealer was still unwrapping mine that the exhaust does come with the insert installed. Here is a pic of what the insert looks like and it's held in place by one bolt as far as I can tell. Might be some "free" hp there, I don't know how they rated it. The muffler is definitely a straight-through design.
nothing different between that and the Akrapovic full system exhausts that have been available since the bike was released. removing the db killer won't do much for power at all. the main power restriction on the HP4 is in the midpipe. you'll have to replace that with the basic unrestricted midpipe in the regular Akra full systems, and there's surely 5-10 more horsepower to be had with a PCV...the HP4's peak power is rated the same as stock, although I'll bet it dynos out a little higher.
I'm leaving the cat in, I've come to hate the smell of unburnt hydrocarbons when I'm riding on the street. If someone starts to hand me my ass where I live then I'll do something.
There is a race kit available, not sure if the stage 1,2,or3 goes into the cases of the motor. I'm sure with the stages your warranty is definitely curtains.... I am getting my racekit installed on weds. then I will dyno it shortly after. They said they will remove the break in code with the new controll unit. Spring I will be getting the calibration unit and code.

I honestly want to set the sag and how it works stock.... I have a while before I can ride... So I have some time... I'm sure over the years the DDC will be amazing, first round might have some bumps...
