Hey guys, hoping someone might be able to check out my suspension and tell me what is wrong with it. I have an 06 zx10r, I bought it like this and I'm pretty sure it's been lowered in the rear because everyone always asks me if it's lowered. I'm 5'9" 145 and I sit completely flat footed on it now. I want it back to stock height because it handles like a tank now. At first I thought it had lowering dogbones on it but now I see they appear to be stock, they say 0018 on them. I was also looking at complete rear shocks on ebay and most of them for this year are black with a silver spring whereas mine is gold with a red spring. I don't know if that makes a difference or not. Thoughts?

It looks exactly like my Gen 2 suspension setup. Your spring colour is correct.
You can add a 6mm shim if you want to raise the rear end. I did it to mine and it seemed to help turn in (that and replacing my rear spring with a Racetech).

Just to add; The black/silver shocks you see are from the 2007 model. Your setup looks stock as far as it is possible to determine from the pictures without measuring.

Thanks for all the replies. So if i pull the shock what should a stock one measure eye to eye? Do you guys sit flat footed on your bike?

Im 5'9" and 140 and i flat foot it pretty easily. As others said, that the stock shock. I have a 06. Try messing with your spring rate, sag and compression. Mine is soft enough i can make it floppy feeling even with little ol me on it. That doesnt mean its a good compliant shock but at least the range of motion seems to be there. Dying to get me some Racetech gear on there though.

Thanks for verifying that it's stock. I shimmed the rear and I will play with the preload and compression and see what I can do with it

Bringing the thread back for a couple more questions. Ive been thinking about getting another rear shock possibly from something else like the gen 3 zx10r. This is a better shock no? Are there other options that could benefit my gen 2? I know there is always the ohlins etc but no looking to drop so much dough right now. Also Ive been asked if my front fork springs have been shortened. I was wondering if someone could verify this for me. Right now as the bikes sits from the bottom of the fork seal to the bottom of the tube is about 93 -94mm in length with the bike on its wheels. I know I could take out the spring and measure it but thats a lot of hassle. Also been thinking of getting the front forks revalved. Any good recommendations?

Save your money on getting another OEM shock. The amount of hassle and time trying to make it work wont be worth it.

As to the front end shortened you have to take the forks apart to get the right answer. If the springs where "shortened" the rate changes and they would feel much stiffer. Best thing is to have them taken apart and inspected. Preload also affects where in the stroke the forks sit.

As to revalving the forks, I'd recommend (in no particular order) Ohlins, K-Tech and Bitubo. GP and Penske are also an ok option (in my opinion and experience). I'd stay away from Race Tech. The price and what you have to do to install them is not worth it.

Can you elaborate on that a little? I was pretty set on Racetech simply due to affordability... Not all of us can go out and blow a grand on a rear shock for a bike that may never see the track but from just hearing you and LDH talk it sounds so black and white - either blow $1500 on a nice piece or just stick with the stock trash lol.

Although a terrible inaccurate method, mine is about 99mm if this helps you. With the bike on the side stand. Depends on your preload as mentioned. And also on stiction, where the fork rests.
Have you considered just respring for your weight and service what you have to see how it feels? Potentially 11 year old oil won`t exactly make the stockers do their best. Then you can save up for something better later.

Well I replaced the fork seals about 5 years ago and put new oil in then. I thought about respringing the forks as well but I'm only 140. Shouldn't the stock springs be adequate for my weight?

Ok. Shock needs service too, and probably time for your forks again. Stock fork springs might be a little too stiff, and rear a little too soft for you. It won`t be free as the shock must be done by a shop, but it`s probably a better option than trying to make something else work that won`t, and on top of that is already in need of service too.

I bought my Gen 2 with 15k miles on it and the stock suspension was so wasted that it nearly fell off the sidestand to the right. I have a 29" inseam and could easily flat foot both sides. As the manual said the seat height was over 31" I knew where the problem was.

Dealing with Dan at Traxxion for a complete fork revalve with their kits(not AK20), springs for my weight and track s/u including the labor was under $700. Adding a Penske 8393 s/u the same was another $800 or so. Best $1500 ever spent!

Question.

Has anyone used a Nitron or YSS rear shock?

Can't seem to find a YSS shock for 06~07 which I find weird.
