I have been seeing a few members have installed ZX10 rear shocks on their 9ers. Looking for any info on install tips and tricks, along with settings. Feel free to chime in on your experiences and what modifications were necessary to install. Thanks in advance.

I have a Marthy's built thread with some pictures. If fit right in, just need to drill one end of the shock bigger for the fz09 hardware and little bit of trimming on the under tray plastic.

When I sit on the bike it drop 28mm. Start with that. I will post my setting later on just to give you an idea where to start.

28mm of loaded sag (bike, rider, and gear) is a little tight in my opinion, unless you are riding it quite hard/track days/etc. I'm not saying that won't work, but the ride will be a bit on the harsh side. Ride it like that and see if you think you may need to soften up the sag setting a bit. YMMV!

That's not total sag... just +28mm when I sit on it. The shock is 6mm longet or so. To keep the same ride height I end up with more free sag. Feel good but Im sure somone can optimizes the setting better than I do. Riding in Florida kind of sucks!

Thanks Marthy, I have checked out your build and am just hoping that there may be some more photos of the process. It seems I may need to acquire a shock to size it up and visualize better on installing it. As far as adjustments go, are they clearly marked on the shock?

I have my sag at 30mm. 1 turn out on compression low. 2 out on compression h. 1 out on rebound. The front now feels like it needs help.

All I was looking for was for the bike to not chop sideways on bumpy turns. I got that and a smoother ride. I hear the spring is soft but I have yet to bottom out the shock. Even on bumpy roads. For under $50 I'm happy as a pig in poo.[/I]
How do you like it compare to the OEM?

Still waiting for my ZX10 shock, will start with Marthy's settings when I get it. If you wouldn't mind letting us know your weight in riding gear. And are you an aggressive "twisty" rider like me, or a commuter, or what? The ZX10 shock, thanks to Marthy, is going to be a popular mod. The more info on set-up we have, the better it will be.

It's too bad Marthy lives in Florida, and only gets to ride in a straight line (ha ha). Go hit some freeway on-ramps hard, Marthy. I don't know about Florida, but in the Seattle area, we got some kick-ass on-ramps that come around almost full circle. The only problem is getting a big enough gap (with our traffic) to really enjoy them.

On 2 wheels I don't trust the pavement cleanliness of ramps etc. I guess in the city you make do with what you have. ;)
I actually live in the country, about 25 miles from Seattle. I rarely even ride on the freeway, but when I do, I'm lookin' to strafe an on/off ramp or two.

I am a svelt $180 lbs in my sexy birthday suit. I ride with full gear but don't know what I weigh clothed. I live for the curvies and some classify me as agressive.

Thanks to Marthy for pioneering the ZX10R shock mod. Got mine installed yesterday (bitch to install, and set sag). Went for a ride today. Bike feels much better damped and firmer, front and rear are now working in unison. Temp was 40F, wet roads. sand in places. Not the time to hang it out, had a moderate pace going and felt confident. No more chassis pitching over bumps, or off/on throttle. Made the throttle snatch in "A" mode better just because the front didn't dive, and the rear didn't squat (at least very little compared to stock).



The rear is now 3/4 inch higher than stock, which is perfect for me as previously I had the front forks pulled up 1/2 inch in the triples to get more weight on the front end (forks are now back to stock height).



I'm 170.5 lbs. in my leathers. The 2009 ZX10R shock is maxed out for pre-load, to get me 33.70 MM of total sag. Although Marthy is around 20 lbs. heavier than I am, and say's it works for him as well, with the stock ZX spring rate.



I am currently using the same settings as Marthy: High Speed Compression 3 turns out, Low Sp. Comp. 3 turns out, and Rebound 2 turns out from full stiff. I'm sure these settings will change a bit when I am able to ride in anger.



With the front and rear mostly sorted, for less than $135.00, and the ECU re-flash soon to take care of the throttle snatch,remove the limiters, and timing retard, the FZ is transformed. This is the way the FZ should have come from the factory.



Thanks to the guys developing the FZ: Nick at Stoltec Moto, and those he is working with, and Marthy who built the first pipe for sale, and put the ZX10 shock on.



I feel now the FZ-09 is as good as my old Street Triple R's were suspension wise, and will soon be fueling wise, but with a lot more power.



It's an unbelievable bike for the money, especially with a few inexpensive mods.

My question is:

I have my ZX-10 shock in the garage, I'm about 200 geared. How do you expect it to handle my weight?

I'm going to find out soon...but I'm curious what to expect.

Glad it all work out for you. I didn't pay too much attention to free sag, it felt a bot too stiff for me. When I sit on the bike it sag another 28mm. Feel good for the type of riding I do. Anymore preload felt like the bike wasn't transferring weight tye the back enough. So as far as RH I think the rear end is about same as stock or 3mm lower, the front is drop 8mm.

Zlo, I think at 200 you mightend up near the limit of the spring... depending of the type of riding you do. I would recommend that you swap spring and install the oem spring instead, that should be enough.

So far so good, only put around 40 miles on so far. Dry day today, will get out and put on some more miles.




I agree with what Marthy said. Might be ok depending on the type of riding you do, and experience. Otherwise just try swapping springs with the stock shock. Good luck, post your findings when done.

Not entirely sure how I'm supposed to swap that spring. Looks to be an impossible task. I guess I will have to loose weight!

Looks like the zx14 shock might be a better option for us 200# in gear folks. Looks like same basic shock design and length but with heavier spring.
