no 6-7k dip anymore...but new 5k dip....LOL

 

:lol :lol... The graph is a real shame, if it really is legit. :fact.

 

It's totally unacceptable. Look at it. Very poor IMO... If this is what the new '09 R1 has to offer in it's power curve it's not looking good without some custom mapping.

yeahh ...me to think same...its not good....look at the torque curve..... bad dip everywhere...:dunno

sorry guys, im not intended to break ur high spirit of buying 09, but its the fact we have to face....

if its real, then i dissapointed (again)......:no

 

where did you get this info from?
not calling you a liar...but...a little printout isnt convincing.

 

Where did you get the graph from?

www.akrapovic-exhaust.com

find the exhaust for 09 R1 and then click it....there will be installed exhaust pic with dyno curve supplied....

see that graph before, its on another thread, seems legit. Any one been to the akra website yet?

Akrapovic's website. You can go click on it under new products. diel11 said something about it possibly having to do with the firing order. Though I don't quite understand how that would be the case as the dyno should only be measuring what hits the pavement.

Also, the slip on's were dyno'd with no PCIII or any other mapping. There is probably a lot of power stuck in the cat's.

 

Why does the graph fall off at only 10,000 rpm?

 

yeah...im thinking about that too....the graph looks veryyy flat from 10k til 12,5...
its different with 07-08 which hit very hard from 10k-till 12,5k....

also the 5k is very weak, the torque itself fall at that rpm ....

need someone buy and ride it and review for us (honestly/not bias)....

 

This graph is a 03 gsxr750 that Tim Radley at Race Developments made into an uneven firing order engine. Notice anything familiar? We are used to seeing graphs from 180degree firing orders. So anything else will "freak" out our perception. And to tell you the truth, his motor actually lost power on the dyno, yet was faster and faster on the track.

I think that's going to be the problem with the 09 R1. People that are looking for hp or strong dyno charts won't see or get that. But real world performance should make the power delivery and traction much better. I've seen graphs of motec equipped R6's that look the same when T/C is kicking in. We'll just have to wait and see.

 

Just curious as to why an R6 would have a problem with wheelspin on a dyno??????

 

Do you know what the seat of the pants feel was like on the GSXR project? I think I have a pretty firm grasp of what the uneven firing order should do in regards to drive characteristics, but must admit, I have never seen a dyno of one until now.

Are the torque jumps actually felt while riding? In my head I was thinking turbine smooth with a lot of grip. I'm sure the grip is still there, but I can't figure out how the lumpy curve would not be noticable on the street.

I'm sure its not, Yamaha wouldn't be stupid and introduce it if it was. But my question is why/how thats possible?

 

The bike was raced by Tim and also ridden by Guy Martin, and the consensus was "it's so easy to ride it feels slow". Serious traction and smooth power delivery. The best way they described the feel when getting on the gas was "electric". Something else said was if you started to lose traction, everything happened slower than a normal firing engine, so you could get it back easier.

I hadn't seen a dyno chart for a crossplane before but did remember seeing the one for Tim's project. After we saw the Akra one, we talked and that seems to be the reason behind such a different torque curve.

 

waiting for expert to chime in here....tell us....

 

That is just piss poor in my book. When is Yamaha gonna wake up and build an engine to match the awesome Chassis they build?? I mean come on!!!

 

 

Full system?

Interesting curve. Thank you very much diel11 for your insite. I can't wait until we finally get some ride reports. Looks like Yamaha is going for actual performance as opposed to being the dyno king. I see nothing wrong with that at all.

 

Are you serious??

 

god damn it...even a full system still have the dip everywhere...oh come on yamaha.....
i ve been put some money down to order an 09 here......dont make me cancel it....

 

so $11500 plus $2000.00 extra for full system $350.00 for PC3 and i can get the same power as a 04 to 08 and stinkbug/Darthvader hybrid ? where do i sigh up?

 

some old 07 hp and torque dyno.....just for comparison...

 

is the test done by those journalist who test rides them? this kinda doubts me because majority of the journalist are riders and i put their experience to a challenge against one who worked on bikes for couple decades. anyhow graph is a graph... its going to fluctuate over years. just the beginning.

 

never mind previous post. dint pay attention to all the threads... :crash

 

ummmm man I'm not impressed....

 

i'll let my butt dyno be the judge

 

has anyone else noticed the tq is over 100? ridiculous for a liter bike. why does everyone only care about hp curve, the torque curve is pretty nice imo.

does seem odd that the hp drops off wayyy before the tq does though.

105 is in Nm, same with 77,44 ft lbs.... :thumbup

 

77 is still a dog compared to zuk and kawy.

pulsed power is a good thing. If you want torque, just get a Duc. unven firing pulses leads to better cornering (or in the case of a twin, since you get 360 degrees between pulses it's basically the same thing, especially with the lower RPMs such engines run). Rememver the ZX-RR with the screamer engine Kawasaki was testing early in the MotoGP season...then dropped? Saw that coming a mile away - if the bikes were slow in the corners and spitting riders off, the screamer engine would have just made that worse, no matter how much faster it would have been in the straights.

 

I agree with everything you say but it is quite clear reading just 2 pages of replies here that there will be a big portion of people who are only interested in dyno numbers. Some of us know dyno numbers and real world are two very different things, but some do not. Unfortuntately many will probably fail to realise the potential of this awesome machine because they just want SHOW and BRAGGING RIGHTS - hence hating on looks and dyno numbers. That is such shame.

As for how these things ride. As Diel said, the grip is fantastic. But i'm talking on a racetrack here where the bike is being pushed to the edge which again does not happen on the street much. Its harder to highside a big bang because when it lets go its much slower. And they are very deceptive just in the way a big twin 1000 is, you feel like you are going slow until you look at the speedo. This again is great for you track guys because it means your brain spends more time on stategy and lines than it does on a bike that feels stupid fast.

Look at Yamaha in Motogp. They have one of the least powerful engines over the last 2 seasons but have more bike in the top 10 than anyone else. That surely has to say something for their ability and knowledge. So i would not write the bike off just yet.

 

Just wait and see before canceling orders....my personal advice:secret:

 

Exactly. But I was just wondering. How come Akrapovic put out the dyno charts this early on? I wasn't expecting something like this to come out this early. Dang!

 

HERE IS THE PIC OF THE 2009 R1 WITH THE FULL EXHAUST, STILL LOOKS BAD IMO....

 

Tim owns Race Developments. Serious headwork development there. I think some of the videos of his GSXR are in youtube.

 

That curve looks worse than the bike, a tough feat...
