I found a 03 ZX9 dirt cheap on ebay so I picked it up and decided to see if I could fit it to my bike and see if it handles any differently. I read about the 10 arm swaps and some of the earlier ZX7 arm swaps also.
Good thing I have aftermarket wheels because there is no way a stock 12 wheel will work. The good thing is if you tried to install the 9 arm you could use the 9 wheels as the 9 front wheel can be made to fit the 12 and the rotors bolt on.
The stock 12 wheel is offset to the brake side when mounted and the hub is too wide/spacer is too short to move over. With the marchesni they use a narrower hub and a big spacer. A new spacer solved the problem.
The arm itself uses the factory pivot, spacers and other parts.
I had to come up with a brake set up so I decided to try one of those tiny 4 pot brembo knock offs you see on ebay. Machine work on it is pretty good although the anodizing is some putrid green/gold that looks like ass. Some black paint fixed that flaw. The pads in it are some oddball size and nobody lists any that are even close. Looks like when they wear out I will have to mod a set from another bike to fit.
I had to machine a caliper carrier so I got a big hunk of aluminum and went at it with a hack saw and file for a few days. :lol:
I still need a new brake line and also need to remove some material off the carrier. I didn't want to waste time whittling it down if the set up wasn't going to work.
With the stock master cylinder the little sucker is really firm with lots of feel. Too bad it has almost no power but then again the pads aren't bedded in plus who know what compound they used for it. There is no way I will lock the rear wheel at speed so that solves the touch rear brake problem some complain about. Oh, I also reduced the diameter of the rotor too for less weight. It is about 1/4 inch smaller now.
Why swap it? Because I can. :crackup: It is 1 inch shorter plus stiffer due to the bracing. I don't have a scale so I have no idea what it weighs vs. the 12 set up. The tiny 4 pot rear brake set up is quite a bit lighter than the stock anchor.
I just got back from a short 30 mile ride. I didn't get to take my full test loop as there was too much traffic (I picked the wrong time to go for a ride with all the soccer moms picking up their rugrats) and some construction so I said screw it and cut the ride short. It did quicken steering a touch but so far it isn't twitchy but then again it could be if you like top speed runs. I have it set up for the canyons and such. Sprockets are -1 in front and +1 in the rear.
Draw backs so far are no flipping rear huggers to be found for it in this country. I bought one from ebay who I think was pit eck or a close cousin. Holy crap, what a heap of shit. I might use it for a basis to make my own. I'm not great with fiberglass but it I have to be better then the one these blind monkeys shit out. :angry:
I don't think this would fit with the stock shock as the brace would hit it.
You have to break the chain to install the arm.
You need different wheels and a machine shop to fit it.
I could have went the route of the 10R arm but there is no way the 12 wheels will fit the 10 arm. Even the marchesnis would require some hard to find and expensive hub parts to fit and even then they may not.
Sorry about the zip tie brake line holder. I need a new line and have to make some way to retain it if I decide to keep this set up.
