I was wondering if you would post some info on your Race Link. How it was developed and results you have found. Laptimes improved? The problem I have had is getting on the Gas after the apex. I have highsided myself to the moon. Traction seems to be a problem and it's not a spin that I can control.

do you have 30mm triples? without them you need to jack the rear up and I highsided because of it then I got the triples and you lower the quite a bit.

[TDARE]

Yes I do have the triples. I have also had Computrack (Ken) mesure and setup the bike. I know the Pros are running a longer swing arm.

The development is from my years of working with different versions of the Corse links which have little rising rate compared to the stock rising rate links (916, 748, 998, 749's, 999's, 848, 1098's and 1198). The 749R doesn't come with a rising rate because was intended for WSS where you can not change the link like in Superbike same reason they come with adjustable triples.
We tested the 1098RS Corse link with Doug Polen and Ryan Elleby olong with our version which has just a little more rising rate than the Corse but much less than the stock link. For two reasons we did this: 1) because the tracks here have more elevation changes and banking where than Euro tracks and 2) because this requires the shock to only be 7mm shorter instead or 11 so no internal shock work is needed (adding a top out spacer) so can just screw on the shorter eye end (Ohlins or Ducshops).
With a rising rate link the shock gets progresivly stiffer thru the stroke which puts al the load on the tire (tire becomes the suspension) causing the front end to get light, tire spin and tear up the tire prematurly (soft = grip). So with the flatter rate link get good feel all the way thru the corner allowing more corner speed and exit steering, will also pay for itself in tire bills because of extended wear.
Dont get caught up in needing a long swingarm, you dont. Your's is as long as the old 998RS's and you can adjust yours back to the starting range used in current AMA/WSB. The main reason for the Superbikes using them is more room for a wider/taller tire and more adjustabilaty.

Mark,

What change is needed to adapt a TTX with your link?

[Ducshop]

Just the Ohlins or our eye end, ours is $63 and we made it out of 7075. You will need to run a 2 to 3 stiffer rate spring so if an 8.0 works for you now you will need a 9.0 or 9.5, if you are running a stock 1098 ride height rod you will want to shorten it 14mm, just chuck it up in a lathe and take 7mm off each end.

Hi,
Do you sell a linear linkage for the 998 as well?

cheers

[Ducshop]

No, we used to get the ones RAM made but dont know if they make them anymore, Yoyodyne used to sell them so maybe ask them.

Thanks very much for the info. I need to decide what to do.

Ok, thanks!

Are there any options to run a du511 shock with your link. I have had some work done to the shock and would like to keep using it, but would like to benefit from a linear link as well.

[Ducshop]

We are going to do some testing at a track day Feb. 27/27 but the numbers look good if you use the 511 with our new Daytona 2 position link. You would have to use the "Daytona" top position with the 511, it's rate is half way between stock and Corse position and you will need to run at least a one rate stiffer spring.

This is our prototype we tested with a TTX.

They are almost done with the CNC work and then go to the anodizers so maybe late next week will be ready to ship. Think we will make them in black or at least half of them. Price should be $575 like our original and you wont need the eye end.

Well I'll have to make a decision i guess, maybe compromise the 1/2 linear rate vs an expensive convert to a ttx/eyelet/link combo. Thanks.

[duc1098]

I have the Ducshop linkage with the modded TTX and 30 mm triples. I am running Dunlop KR slicks with 125/80 front and 195/65 rear. 520 gearing with one tooth less on the rear and the bike rocks! The linkage is great! Make sure you set your rear rider sag at 28-30 mm rear and 40 mm front with two lines showing above the top triple clamp you will be in the ballpark. I have about 3.5 threads showing above and below the ride height adjuster. Anyone interested in setup info, I'm happy to go to the garage and double-check.

Good luck!

Well I can't really take setup dimensions via internet, at least until people know what I'm running. I will run 28mm offset attack triples, which are holding on to ohlinsfg570 forks. I will most likely setup the ride height in testing when I can get numbers from a co-racer on a Duc 1098. I'm sure there is some variance to fork tube length etc.

with running even less offset be careful with the radiator as the tire will probably hit easily.

I have the same setup, do you mind measuring the ride height adjuster from eyelet to eyelet (in mm). Just curious as to the ride height you are using. thanks

[Ducshop]

Just got our new links and eye ends from the anodizers today. It's a 2 position now as we tested at Daytona last season with Matt Lynn, Ryan Eleby and Hawk Mozatta.
The lower position is the same as our original race link with the top position having a rising rate between race and stock, referred to as a Daytona link. This is similar to what Ducati Corse has always used in the past for U.S. tracks giving the teams 2 rates to choose from.
Forum price is the $575 retail but you get the $63.75 eye end free.

Hey Torch, your forks are longer than the R&T's, so you will need more of your forks pushing through the triples.
I think DK has pictures of his gas forks and triples in his forum section.
From memory the gas forks are 30mm longer than the 717mm R&T forks.

I'm having difficulty finding a recommended rear ride height for the DucShop dual position link. I'm using 235mm as a starting point using the Kyle ride height tool measured to the center of the axle. Is that in the ballpark?

AWESOME customer service and products at DucShop by the way! Thanks to Mark, Wendy, and Nathan for the quick turn around.
