polarissnowx101 01-28-2008, 10:19 PM I am looking buying a rear shock to replace the stock on. The shock I am looking at getting is off of a 03' Buell XB9R. It has a remote res that I don't think will be too hard to mount. I will look up lenth, spring rate, things like that once I post this, and will post those later. Does anyone think this will work or have anything against it. The only reason I'm looking at it is first because it is local, and second that its diffrent, its not something that I think no one on here has...
enrico vespa 01-28-2008, 10:24 PM if you think it'll fit, go for it..... depending what it's selling for.
polarissnowx101 01-28-2008, 10:29 PM what do you think a good price to offer it is? The shock is a Showa shock with adjustable compression damping, rebound damping and spring preload and 5.0 inches of travel. I don't see why it wouldn't fit...
fluke323 01-28-2008, 10:34 PM **** I wish I had thought of that, thats a nice set up. The thing you should really look into is the spring rate, because it makes no difference what a bike can weigh, it just matters the amount of leverage on the shock. I was just watching a video by traxxion dynamics (suspension for mortals) and the guy kept saying that a gsxr and an f4 weight about the same but the gsxr only needs about 500 pounds/per inch compressed and the f4 needs almost 800. I think the SV with an average rider needs anywhere from 530-600 pounds (someone check me on this, but I think thats about right).
Good luck, let us all know how it turns out!
enrico vespa 01-28-2008, 10:35 PM Thing is, offer what you feel you can lose. Paying $100 for a great shock you can't use or difficult to sell really isn't a great idea. If you're not riding your bike for a while, take off your shock and compare them side by side.
Didn't think of this but does anyone here know if he would have a problem with the standard vs metric on this for possible bolt on?
fluke323 01-28-2008, 10:39 PM don't think the metric/standard conversion would give such a problem. It's probabaly a 3/8 and there is enough metric sizes close enough that it could be drilled without risking the strenght of the shock.
polarissnowx101 01-28-2008, 10:47 PM looks like the buell weighs about 385lbs dry. The same site says the sv weighs about 363 dry.
Anyone got a price I should offer, any other input, or ways to mount the res.?
enrico vespa 01-28-2008, 10:51 PM you can strap the res on the side of the subframe.
fluke323 01-28-2008, 11:15 PM I would say $65 to start with and see what he says? And the resevior won't be a problem at all, just make sure you use something stronger than a zip tie. But I'm telling ya, make sure you check the spring rate. Make sure it is atleast 9.3 kg/in.
Assuming it is the same length as th ohlins replacement, the xb9r shock is 357-369mm ( it is adjustable); stock is 330mm, I think. That would raise your rear 120mm (~4.5", huge) unless you fix with dogbones.

polarissnowx101 01-29-2008, 06:36 PM that doesn't sound like too good of an idea to me, anyone else have an opinion? I really don't have a problem with the dogbones, I have full access to 2 metal shops....
I said 65, he came back with 85. I'm starting to think no....

stop thinking about this until you figure out what the spring rate it. The bikes being the same weight doesn't mean diddly. First and 2nd gen bikes are the same weight and use springs 100lbs apart.
polarissnowx101 01-29-2008, 06:52 PM where could I find the spring rate?
where could I find the spring rate?
Best bet has been to look at aftermarket companies and see what they have listed as replacement. that is what i did to find length for you.
ohlins
penske
traxxion dynamics
racetech
etc

If I rea that right, which I like to think I am, it says the buell has a rate of 425 as opposed to the 650 rate of the stock shock, which would mean there is no way as a 220lbs rider, plus possibly a passanger, that I could use this. Anyone have any other shock sugestions and where I could get them?
enrico vespa 01-29-2008, 08:06 PM Sounds like if you offered $35, he would've said $50.

well, it is 500 for the gen 2 but you are correct that the buell shock is too lightly sprung. It is next going to occur to you to swap the spring or something but if the springs are that different, you will never get the valving dialed in correctly.
It was a nice thought though.
polarissnowx101 01-29-2008, 08:32 PM I thought so. I saw it online, and was real excited...O well, I guess there is a reason no one else has one...
Dichotomous 02-20-2008, 11:27 AM you could also change the linkage, not the dogbones but the link itself, to adjust for a differnt spring rate
