Don't worry if you don't hear from them. Both of us never heard from them after ordering but they came about a week to a week and a half later.

Possibly silly question but... do the 250 and 300 share the same stock shock?

Or in other words, do these measurements apply to both bikes? I just installed my gsxr shock this weekend and want to raise the rear back to stock, since it looks like it's sagging a bit lower now. Wondering if the 1.25" raise link will do the job on the 300 as well.

The one he sells now I think is 1.25 and 1.5, so if they share the same dimmensions then that would be awesome to know! Ill be interested in the answer

FYI, the 39111-1133 dogbones used on the Gen2 EX500 are 157.5mm eye to eye. A lot of EX500 owners buy shorter dogbones from FOG to raise the rear end for quicker steering (similar to the topic of this thread), so you might be able to find some for cheap/free (though $17 still isn't bad). Both the 250 and 500 use the same sleeves through the knuckle and swingarm, but the 500 uses 100mm long bolts (92002-1886) while the 250's are 98mm (92153-1831), so the 500 dogbones might possibly be a bit thicker or something.

@InvisiBill good info

Thickness of dog bones should not matter to much for the gsxr shock swap as you need spacers to get the bones to clear the new spring. So you have to buy longer bolts anyway.

I e-mail them and got no response, but I got them about 2 weeks later.

Thanks

Burkhart Cycle has the 08-12 250 listed on his site but does anyone know if it would fit a Pre-Gen? I just did a Zx-6 Air Shock swap and it lowered it quite a bit.

Does anyone happen to know how much clearance you need to add to the dogbones to clear the larger spring? As you can see in the pic below of the EX500 Gen2 FOGbones, he bumped out the center section instead of leaving them perfectly straight. That little bit is enough for us to clear the larger springs that we commonly use. FOG charges a bit more (~$45 a set last I knew), but I'm sure he could whip some up if you gave him an eye-to-eye length (he has standard "raise your EX500 to the best height" bones but also does custom lengths). Some people might prefer to pay a bit more for PnP bones rather than deal with longer bolts and spacers and such, if a bowed dogbone like this could work for the GSXR shock too.

And on that note, is there a difference between these two?

I thought maybe the GSXR ones might have a bow in them to provide some extra room or something, but the description doesn't mention anything about the construction being different. The GSXR model just has a couple longer length options than the regular one.

NewGen and PreGen are totally different.

Gen1


Gen2

Its a good bit, People were using 1/2" nuts as spacers or something similar and you figure they have to be close to 3/8th wide give or take. One on each side


edit: There is tons of info buried in this thread, but here is a particular post that you might find helpful from it

[warning]

Does anyone know if the rear linkage on the 250r and the ninja 300 are the same?

[Tiller]

Could someone confirm the oem link center to center on the 250. The the ones I have, have been drilled. I come up with 164.5mm 6.476''.

I made some at 155mm for a race bike and it seamed to work. I'm trying to figure out from the oem piece and the info in the earlier post the amount of change per 1mm. 158.5 for 1'' and 156mm for 1 1/4' . That would be 6mm per 1'' or .1666 per 1mm. If I figure 8.5mm shorter for the 1 1/4'' rise links it comes to 1.416'' rise. So to me the numbers don't work unless it has something to do with an angle change as the link become shorter so the relationship between link length and swing arm at the axle would not be linear.

Hi Bruce, if you talk about the new-gen (2008-2012) then your right, the center to center measurement is 165 mm.

No, that would mean I'm a half mm short. So 165, let me play with the calculator.

Hate to dig up an old thread, but correct me if I'm wrong, the change of dog bone length and how that relates to overall rear height of the bike is not constant, right? Because this relates to the rear, and it pivots. I'm trying to map this in my head. Thanks.
