Im in the process of making a deal on a new zx14r and i am wondering if my akrapovic full system will fit on the new bike , i know they will probably come out with a better system but just the sound and weight reduction are wor th it to me to keep it if it will fit , im selling the old 14 and have a boz bros duel slip on system i will put back on with the stock header,also are the sprockets and chain the same ? I know theyre still 530 pitch but i have two new spockets i would like to put on the new 14r rather than sell them with my bike if they will fit the new one as well , thoughts ??

Hey Fuel
I had the same concerns and according to Brock from Brock performance the current exhuasts will fit the 2012 ZX14R so I imagine the Akrapovic should follow suit and fit as well.
Be Well
Snuffy

For sure, any exhaust header which fits a 2008+ ZX14 will bolt up to the 2012 fine.

I haven't heard yet if the collector and pipe(s) and muffler bolt up the same places on 2012 as pre-2012 though.

Nope, Head and front engine block are in the way. 4mm higher in stroke. Send your '06 to '11's to privvy. He is going to weld 4 more mm in height so they fit. Then oval #4 header so it fits, moving away from the front balancers or something is in the way.

Hub why if brocks says they will fit do you think they wont, and just because the motor picked up 4 mill in stroke doesnt mean the block height will change as a matter of fact the head and the block are the same , and what about the sprockets no one answered that question

Correct, just because of a 4 mill stroke does not necessarily mean that the outer dimensions will change. IE- 350 chevy with a "striker crank"= 383...
According to friend that went to dealer show in Florida, he said my pipe will bolt on. After reading what Brock said in his testing thread on bikeland, if you do not use a pipe with 2.25 diameter or better you will hurt the HP. He gave an example of a bike making 216, then with a pipe that is only 2" diameter the bike only made something like 207....

Where are those promo photos. Bring the right side. Bring the cut-thru-cut-sea of parts. Look at the front adamsapple on the front case/crank balancer. Is that more in the middle? Or is that in the same place? Brock should know. He knows were to look and what I mean.

Next is, I measure the pipe's O/D between the new and old gen pipes at the header. Sure enough in mm's does it grow. If you think 4mm is inside the engine, case is the same, no mm in height changed, my mistake in thinking and photo op, being deceiving to me then.

Then again, we still have an oil filter issue? Is that not a new oil casting there? What are those 4 empty holes by the oil filter housing? I say, wait and see. I rather see it physically happen, not at some show thinking yeah? Unless we have that photoshop pipe WAS a Brock and it bolted right up. That is my hez to say anything concrete. Show me.

I guess you can call Brock and ask him if you buy his ct pipe now will he guarantee it will fit the "r" model,

wee

He has 06-12 listed on each pipe, I would imagine he knows definitively or else he is going to have a shitload of pissed off customers. I am considering his Gen 4 20" polished full system ATM.

Do you know how big a 350 engine is? Do you know how small the bike engine is? 4mm on an engine is huge. 4mm on a V-8? Think about it.

Yes Hub, I do know how big a 350CID engine is and I do know the size of a bike engine. Yes it is a nice gain, but that was meant for an example not direct comparison. I do know how big 4mm on the stroke is. Hub do not take offense to the pics being posted below, many of the people here have no idea what or how we are discussing so the following pics are for them.
Regular is:

and Stroked is:

In other words everything can still fit inside the "stock" cases providing the cylynders have enough space to accomodate the extra 4mm.

Valve stems are longer. I just don't know? Too much going on. I'm just seeing that gap at the oil filter being taken up somehow. That head has to grow too in proportion to the extra length of the valve stem, no?

I am not sure what they did with the valve train, I know the cams were made a bit more aggressive and the pistons were made lighter (same bore), oil system changes and journals beefed up. Obviously they had to change the valves around but what if anything did they change? As the head goes it is now "hand" finished which means there can be quite a bit of variation from one to the next.... I dont know either brother... but I want one ;-)

Don't really know if they (current 2008+ exhuasts) really will fit or not, but I think that this is compelling evidence to say that they probrably will fit.... Maybe you can call roaring Toyz fof info? jm2c....

Of course - this sould be just a slip on...

I saw at least ONE pic of Brock's exhaust(looked like an Alienhead or Megaphone slip on to me)that pic had been doctored(not the Roaringtoys one).His site does say will fit(several systems) the 2012.IDK.The pic was most likely just to show what she looked like on a new 14R.I'll most likely get a set on CF 16"ers,the CT
s.Nice looking on any 14.Lighter most likely as well.Don't know yet about a full system...if it'll even be a worthwhile upgrade.I'm with Hub though on the engine height.I think the outside IS taller.That cutaway shows the 'mid' piece in that silver color(guess that's the actual piece and color of it).Looks taller to me?4 mm change up or down is gonna throw everything off.BUT...I suppose if the earlier engines and systems had enough space already engineered in,you might be able to get away with it.As for oval header pipes up top,IF that's different from before...well...there ya go...no swapping there.I want to find out where those cats are...and see if doing away with those are gonna be okay as far as engine safety is concerned.You can see I know nothing about Cats and emmission stuff for these(or any)engine.I don't think this is a simple 'stroked 14' from the earlier engines.

That silver pc is the head and it looks taller to me also. So like I said - not sure if they will really fit...

See any headers in that hardy har har?

Air is my gap is crap is this?

* Last updated by: Hub on 10/19/2011 @ 8:21 PM *

correct they may not be in there Hubabuba

wee

I think that I noted that....

Of course - this sould be just a slip on...

RIF - (Reading Is Fundemental)

Besides - Brocks makes this system as a full system as well as a slip-on...

Ive read every article that i could find and in all the great detail they went into explaining all the changes they made i never read that the block was different or the head ,of course the head is fully revamped but still the same casting ,and if my system has to be massaged a little then so be it. I mean i know my midpipe is .2.25 on my akrapovic system so im certain it will at least maintain horsepower not lose any and they cost $1200 new so if i can use it i will, im gonna make some calls somebodys gotta know something for sure

The bike looks like the same bike, right? Something grew 4mm in proportion. Radical cam? Show me how you can look at Rook's cam shim photos, see 4mm of stem growth happen. Just for argument sake, do you cut the valve seat deeper so the stem in length can be pushed farther up the head? Now it sits there longer in the open phase, while the rod comes around, the valve waiting and all that?

I can't see how you could not grow that head to be in the same proportion of the port's cc's? Did we not expand the compression chamber with more volume [w/4mm of sending the valves up the head], but where is our 12.5 from 12.0:1 CR [compression ratio]?

2011 zx14 engine2012 zx14 engine

Other than appearing a bit more stout at the exhaust headers(directly at the #4 exhaust port and along that front side)they actually look the same depth.If you look at the balancer spline coming out there at the #4 exhaust(may just be a bolt,IDK...but the angle is the same as the top zx14 motor pic...going across from the CCT...it looks the same position wise on the casting?Maybe those headers WILL fit,assuming they're not oval shaped?The thing that makes me think they won't is at the bottom,where the 4 pipes come into one...that connection right there.The earlier ones don't have that...only that round deal just before the midpipe.So....the welded mount points on the aftermarket(previous)pipes MAY NOT LINE UP with that"longer intermediate"(if it is)piece being where it is.Not sure WHAT those 4 pipes are going into...looks like a cat...but it's definitely different than the earlier systems.Otherwise,up top at the flanges...they all look the same as the earlier ones.Didn't they say the headers were actually bigger in diameter,and conical shaped going down?Thought I read that in the engine review(s).If so....so long to switching the headers anyway.

Just an observation here...going to that other post where Brock said something about "Kawasaki may have done their homework with this new porting and exhaust(header)thing"[sic].Basically,it sounded to me like he was (kind of)dissing the other guys who're talking about their systems for the new one...and (kinda) prepping us for...maybe....being careful about running out and spending a bunch of mon on a system that MAY be unnecessary?That's kinda what I was getting out of what he said there.He was afterall...including himself since he IS a systems builder.He may be right.New headers may be unnecessary with this new engine?Mufflers?Ya...probably something more free flowing...I could see that.

IDK...looks to me like that header port connection up top is beefier as well...something's different.

It looks identical to me imo

Hey, if that pipe fits, that says all is profit for Brock so he can buy an R for R&D. Shit is tight. Don't know if they are willing to part with so many if the run is short and better on the floor than distribute so many. Long term bikes are already out. I'd try to blow one up just like bulletproof, but no luck here.

Besides, you'll probalbly break even losing the weight of a Brock and the OEM... 5 little street ponies? Come one!

Go to your right exhaust spigot. Look at the very top of the head. Not the cam cover. Eyeball the top of the spigot to the cam timing line or where you install the cam cover over the head. Does that look like it wenthru a penis-enlarger?
