Didn't get to it and won't for a few weeks.

Was the fitment with everything acceptable?

Honestly, I have little to no issue with the twitchiness of the bike as of yet. Its there but not enough of an issue currently to worry about. I planned on getting a GSXR shock sometime in the future which will bring the geometry back down a little and likely calm the bike a little bit.

That and the front end, I think front end confidence becomes even more necessary with the changes putting more load on the front. Neither of these have any bearing on the links themselves. I may try and get the bike on the track next month and really push the bike to see what the changes are like on the limit.

Fitment was fine in terms of bore sizing and spacing. Once I had the new hardware it went together fairly smoothly. I did have a little issue with the oring/sleeve wanting to push out with the bolts a bit but I think it was due to the longer fastener and the angle necessary to slide it it.

Still pretty happy with them and think they are a great addition to the bike for those willing to accept the compromises.

I haven't installed them yet but I do have some feedback:

I think mine has more milling/machining imperfections than most. It's no big deal, but it might be something to look at more closely when actual production starts. My brother showed up last night, found them sitting on my shelf, and, without even knowing what they were or what they were for, commented that they would probably crack. He wrongly thought that the rounded exterior was load-bearing but there is a line of material I need to file off inside at least one of the eyelets (as if the milling bit went in a big circle to make the hole but didn't go quite far enough and left a tiny sliver of a "tooth" in the otherwise-round eyelet). I haven't looked at the second set yet.

They were roughly waterjet cut, most likely resulting in the lip that you see (and missed when I deburred them). The factor of safety in the material is large enough that they'd need to see insane amounts of load to fatigue them to failure. I can send data if you're concerned

The final products will be much more polished, and cleaner. These are development parts and I'm really just looking for feedback before I make final adjustments. Those who bought in to the development parts will be able to upgrade for free to the v2 links.

Keep the feedback comin!

I was going to ask if they were waterjetted as I noticed the rough finish that waterjetting usually leaves, almost like a casted aluminum finish.

Y u no give me dogbones this past weekend?

Pretty sweet deal there with the v2 links.

Oh, I'm not concerned.

It's not like a lip, but more like a tooth on the inside of one tiny part of the circumference that goes most of the depth of the eyelet hole. I imagine that it once went the full depth but you saw it and deburred it on one side. If the only difference may be the level of polish, then I am perfectly happy and will not be asking for V2.

I'll be sure to send you some before/after shots of the pregen frame with/without the dogbones (newgen suspension). I'll probably drop the front forks a bit and take a shot of that too because the newgen tires/suspension probably raise the rear a bit more as it is.

I had them in my bag, but you were too busy sleeping instead of racing.

[choneofakind]

@CZroe, hit me up later in a pm. I'll send you measurements from my bike so you have a gauge of how high/loa each end of your bike is. My tail is raised like 2ish(?) inches and my front is dropped about .25 inches. Very quick to turn in, never unstable, even under hard braking. Its a good setup and I think you'll like it.

Any chance you have run these in production? I am looking for a set now that my 250 is officially functional shape again!

OK, when I installed them this "tooth" made it so I could only install that particular dogbone on the nut side (unthreaded shaft/shoulder part of the bolts would not fit through). The threads would pass through easily enough (just turn the bolt a few times). These are thicker than the OEM dogbones that the bolts are sized for, which leaves me less protruding threads for my locking nuts. I don't know how many threads they need to lock securely. There was plenty of thread to snug it up but the nuts have unused thread (bolts aren't long enough to thread all the way through).

Pics coming.

[CZroe]

OK, I don't have a good image editing program for sizing and aligning these by the frame, but the images of the newgen swingarm with and without the shorter dogbones is close enough to toggle and see the difference. The front wheel was in a completely different position for the pregen swingarm, but you can see that the distance between the tire and the frame was about the same as the newgen swingarm and wheel. It looks like @choneofakind is right: the aspect ratio difference negates the extra inch of tire size and they end up being the same diameter (never doubted you, dude. 'just didn't know the math/numbers!).

When you toggle the images with and without the shorter dogbones there is an little lift with them. Looks like maybe an inch. Definitely not too extreme. Hopefully it's enough for a hugger.

Should be. You'll have to trim the undertail a little like I did. Check out my pictures and the pregen hugger thread to see what i did to get mine to fit. At least with a newgen swingarm, the hard part of physically attaching the hugger is much easier.

[abhijitz]

Steve - sent you an email with some questions. I would like to get a set. Please reply whenever you get some time.

[!!(0_o)!!]

Email sent

[quarterliter]

Sorry for reviving an old post but does anyone has a measurement from eye to eye on these? Reason I'm asking is because I have a set of links in my garage that may work...

[NorCal_250R]

Any of these dog bones left?

[tac12345]

Bump for leftover.

[sharky nrk]

any more of these? I like them so much on one bike I want some more lol

[mayonaise_invasion]

Not to beat a dead horse, but any of these still laying around?

[DCMoney]

Also interested if you have any left over or plan on doing another run.

Thanks!

[Josh_kcco]

new or pregen 250?

[cbinker]

I got them on my 08 250, and they helped greatly.

[mayonaise_invasion]

pregen. Id like to lift the ass end of my 01. the internet is flooded with lowering links but the only riser options is soupys. having a hard time justifying $100 plus shipping

But if any one can confirm these provide any additional amount of legroom between seat and pegs I'll purchase them for sure.

For those looking for more room between the food pegs and the tank I use Buell drop pegs. One inch drop pegs are perfect.

Brake and shift lever need to be modified a little and the pegs themselves need a little work. The hole needs a little cramming and they need to be filed down just a little.

But my long legs go under the bulge in the tank. Make the bike feel great. They Are expensive 85 bucks. But come in colors

[mayonaise_invasion]

for anyone that is looking for pregen adjustable dogbone that can both lower and raise the bike, just like the soupys dogbones, but dont wanna pay the $100 and want cool colors, I have found the answer. thread coming soon!

I did this a while ago.



Bought enough to do 5 sets for me and my friends came out to less than $27 a set. Not really worth it when you have these for $17.

On this page, they say they only fit 2008-2012 ninja's. Did the bolt diameter change from the Pre-gen's?

Thanks,

Zach

There's a price that's hard to argue with. Thank you for the pointer!

[abhijitz]

When @Rexbo/Steve made these, those 17$ were not available. Infact, he spent a lot of time researching and designing one. If i am not mistaken, the gixxer mod was his idea. True, the 17$ works good.

The thread does cover a solid 3 years from initial post to present discussion. If you're reading through threads about that rear shock mod and using the search function, you tend to end up here - like I did. In that scenario, it's pretty useful to have an up to date source.

[InvisiBill]

Just for future reference, FOG on the 500 forum sells dogbones too. The only difference between the Gen2 500 and NewGen bones should be the length (which he can custom make to anything you want). His are more expensive, but he also puts a little bow in the middle of them, so slightly larger springs will fit without any spacing. I'm sure it wouldn't be enough to fit the GSXR shock, but it does allow the 500 to use the SV650 shock.

If you run out of other options, this is another way you could go.

[bikehor]

I tried ordering from burkhart cycle... sketchy. Google them if you're curious.

Anyway, I did the GSXR rear shock mod and now want to raise my bike back up to at least stock height and maybe a bit more. Is anyone still making these dog bones? or have a set lying around that I could purchase? Track season is starting here in a month so I'd like to have the bike back together by then.

Thanks
