U will be lose...
Trust me
The new cbr is a killer bike
Change to suzuki if u want to beat every litre bike......wahahahahaha

Provided there enough oil in the CBR you're toast.

Suzuki can't beat the BMW.

You're probably losing power with the BMC filter especially since your bike is bone stock with the exception of it.

Oh really?...

You're probably losing power with the BMC filter especially since your bike is bone stock with the exception of it. I'd change back to stock ASAP.

i always read about you raggin on aftermarket filters. what gives? haha. i've always heard k&N and other hi flow brands are great for cars. and bikes. plus reusable.

so fill us in on when its good and when its not good to use an aftermarket filter

ANYTHING K&N blows balls. Sure it "flows", but doesn't filter worth a shit. Of course there is a trade off with flow vs filtration to an extent, but the K&N is sub par. There is other filter media that flows better and filters better.

I love oiled foam filters.

HAHA true on K&N i had one on my old mustang but soon traded it out for another brand when i put the ram air intake on it. Still on stock air filter on the new mustang and bike though.

you'll lose.

if u want to borrow my zx10, you'll win. lol

Lol I just now noticed you guys' posts. Been away from any wi-fi access until now. I'll be the first to tell you that I have no proof of this. What I do know is that most of the "more seasoned" and "more knowledgeable" ones on this forum will tell you the same thing for the filter issue. I have read many, many threads on this and there have been occurrences where bikes have actually lost horsepower by using aftermarket air filters. The only ones I have ever seen that have gained horspower are the ones that have had other excessive work done and the filter was the only restriction. Now with that being said, my theory is that the surface area of the filter is quite large already for a 1000cc engine, the stock filter flows good enough already with the additional pressurization from the ram air. I would not put an aftermarket filter on a stock bike for these reasons and a few more. On a fuel injected engine such as we have, filtering the air is of utmost importance. I compare this to tests that K&N have performed on V8 engines. It is dyno-proven fact that the K&N filter makes more power (to a certain degree) than just running no filter at all. I believe that the V8 with no filter would be the same as the bike with an aftermarket filter. I think the stock air filter on the bike provides just enough restriction to still be adequate for many aftermarket pieces where the aftermarket filter may flow more but doesn't offer any "control" of the air like the stock filter does. I actually just switched out my stock filter for a GYTR so I can get some real-world results on my own bike and have some information to support my theories on it. To put it into perspective, the surface area of the '07-08 R1 filter isn't that much less than that of an '04+ F150 5.4L. That's quite a bit more engine and not much more filter than the R1 has so just in the design of the filter whether stock or aftermarket we know that it flows well over what is actually needed or required. All of this goes without saying the probabilities over under/over oiling and causing detrimental damage to your engine or it's components. I could go into a lot more detail but I think this is already more than what anyone wants to read...

If you lose don't even come back on here. :hammer:

i hate big paragraphs i read the same damn sentences too many times:shake:

If it will flow more air, then it will make more power. Now how different engines react to the extra airflow, is a different story.

It depends on the fuel & timing maps and how airflow is measured on the engine which will effect if it will make more power or not. The extra airflow that is metered effects the injector pulse width and load. You also have to remember that whatever is used to measure airflow, is only scaled to a certain range. If it had proper maps on the ecu, then it would just hit a higher load cell that has more fuel, which will increase the injector pulse width.

It's hard for me to say because I haven't seen the R1's stock fuel map, but like most factory maps, they are rich to be on the safe side, and very blocky. So it might hit a higher load cell, but still have the same pulse width as the lower load cell, which will cause it to run leaner(more power, to an extent).

Lost of people see mixed results, and the main deciding factor is the tune. So stick with the stock filter if you only have little mods such as exhaust, FailCommander, etc.

most R1s and GSXRs are lean from the factory, ZX10s and CBRs are rich from the factory, as you add exhausts , the R1 and GSXR get leaner, the CBR and ZX-10 get more rich

[R1Rider31]

Well is it worth the extra money to know before-hand that you will get mixed results? This meaning if you gain power it will be very minor and there are good chances that you will lose power... I think that's what a lot of people need to look at here.

:2bitchsla :dundun: My 07 feels just as powerful as a K9 I rode with PC, autotune, and full Akra, except below
5k rpm(where I never am at), K9 was nice, but chassis and feedback is nothing compared to R1, BP front forks are better than previous.... nice bike but it does not inspire confidence for me in handling

every bike you buy is the best bro:fact:hammer:

they are all so close, you will not kill anything from one to another except for the BMW...in a straight line of course...

you will get a new CBR soon, and say that is the fastest:hammer:
