ZX-7RR swingarm I know I read it here somewhere...GOZR?
Is it a straight swap?
Is it shorter than the 12R swingarm? By how much shorter, if at all?
Do you use the 12R rear brake components?
How much does a ZX-7RR swingarm cost?

I got mine for $35 off of amasuperbike.com. It does look like a straightforward swap, but the proof's in the pudding!

Probably turn quicker, easier to wheelie and have massive head shake. Of course after putting the short swing arm on you can set your gearing up so the rear axle is slid back as far as you can get it to lengthen the wheel base and slow the head shake down! Sorta of like what Honda did on the RC51. They solved things by making Nickeys's swing arm longer. So go figure.
I think I'll stay with the stock swing arm and merely slide the axle forward if I need things to be shorter. My interst in the 7 swingarm would be more if it is significantly lighter. It appears to be bigger and looks heavier. But it is likely that it looks bigger and actually weighs less because of the internal bracing Kawasaki put in the 12's swing arm. I am going to be had pressed that the 7R swing arm is going to accomplish a lot over a good suspension, raising the fork tubes up in the triple clamps, and raising the rear ride height. The limiting factor I am experiencing with my 12 on the race track is the 210 horsepower and the on off throttle herky jerk typical of the ZX12's throttle linkage.
My perception of the 7R swingarm is it will make the bike more unique, trick what have you. But I am all ears to see how this actually works out.

...and the braced 2003 ZX-9R swingarm?
...and what about swappin' the radial braked forkleg assembly of the 2003 6R/6RR onto the 12R?
...and swappin' the digi-speedo/tach combo of the 2003 6R/6RR/Z1000 onto the 12R
...or will they eventually implement these changes onot the flagship in the near future?

Zhooligan read about the of the ZX12R at the 24 hours lemans The 12 had 230 hp's.
Yesterday I got news from him that they may race again and come into lemans with the ZX12R ressucited..
That will be a great news for 2003
But on the 2001 no one was interested by it , the 12 became the most powerful ever raced at lemans.
I posted his email adress and mail adress a while back for us zx12r owner to cheers him up .
There is so many tricks that you never heard of. we became very good friend and he came to spend some time at my place..
Michel Hauboit won some and participed 19 times at this race.
I wish some time for you all to see one time a Lemans Race In France there are no other races who come close too..
Maybe by helping him or cheers them up we can also be part of the quest and watch it on tv next april 2003..
( interested for his adress or email? )

I would love to go to Lemans and cheer them on. Lets figure out some logistics.
For the record I am not questioning the strength of the 7R swingarm. I am questioning the side effect5s of shortening up the wheel base too much. And what is ok for some top line world class riders is not necesarily safe for mortals. If you watch guys like Miladin, Gobert, Bostrom etc. as they exit onto the straightaway at Laguna they have so much headshake going on that most guys would elect to bail! Ask them about the headshake and they have no idea what you are talking about!

It will be interesting to see what changes are in store for the 12 in 2004...They might leave it alone and just introduce the ZX10R(R) at that time. Maybe they will carry their strategy forward from the ZX6R(R) forward for the 10, of introducing a street and race version. Who knows!

...yeah, swft....a digital speedo/tach ala 03'6R/RR/Z1000 would be much appreciated for quick reference...and radial brakes (just for the wow factor for mere mortals like me) ____________ “We sleep safe in our beds because rough men

I could get into a digital speedo instead of the hard to read 220 mph analog on my 00. The radial brakes look pretty rad too.

HEADSHAKE zhooligan
some of that headshake is a result of several factors
suspension set up..... swingarm pivot location
(adjustable on most racers)
plus the utmost acceleration simply unweights the front end
the worst type is under braking.....very rare these days
or even scarier cranked over leaning 55 degrees
& it starts weebling & wobblin
aint good
not sure if its worth all the effort or if its better
all the front line teams & GP are tryin to get the longest swingarms
possible under their bikes
short wheelbases not withstanding
my main concern would be if the actual articulation of the
suspension is enhanced or compromised
no less if the movement is bound up or remains
progressive..............or linear
suspension engineers usually dont forget about
these primary parameters......... the last 2-3 being constant
considerations for most bikes
it may very well work
good luck

...and a programable shift light with a substantial shift light lens (since there's a good portion of 12R riders who drag race their bikes)...
...and might as well include a longer dragstrip ready swingarm with a heavy duty idler-type attachment somewhere on the swingarm (like a 10-speed bicycle's dereullier(sp?) ) to take up the chain slack when the rider decides to shorten the wheel base for 'normal' street riding...hey...is that kind of contraption even possible?
