S10 ES rear shock Racetech SRSP 6022 series direct replacement spring!!!!

I was just taking some measurements of my bike with the stock spring.
Static in 2 up plus luggage is 46mm. in one up it was about 74mm
With me on the bike it is in 2 up plus luggage it is about 77mm and in one up over 100mm. That is just me in street clothes and sandals. It makes me wonder if my spring is a lazy one.

That is with my bike the way it is when I ride most time. Both panniers on and the top case. All of which just have a few things in them. No wonder my bike blew over in some wind when it was loaded. I would hate to measure the sag with the bags loaded for a trip. I know I did have a hard time finding a spot to park that I felt it was safe.

So with these results and looking at the chart on page one the 2 up with bag setting with the stock spring is the same as the one up setting with the 8.5kg spring. This is telling me I would be better off with the 9 kg spring the way I have my bike equipped as going to 1 up with bags will not be enough preload. I would have to ride in the 2 rider setting. I am going to go back out and take the bags off and see what I get with the bike bare.

Edit: With the bike stripped of both panniers and the topcase in the two up plus bags setting I get 31mm static sag and 62mm sag with me sitting on bike without my gear on. That just confirms I best go with the 9 kg spring. Proper sag for this bike should be in the 53-58 mm range for 30-33% sag. I won't be able to do this with the 8.5 kg spring unless I ride light in higher settings. I want the settings to relate as close as possible to what I am actually doing.
Here are my sag numbers from a few pages back if it helps:

I know this is a old thread. I'm really happy you guys have did this to the ES shock. I personally like Jeffs and Karls solution over the direct fit just for the fact it puts less preload on the spring. Of course the direct fit spring sure makes it easier to do the swap without the hassle of installing a spacer.

My biggest concern with the direct replacement is the fact you have to crank down the preload 25mm-36mm for the range of the ES shock. That's a lot of preload. Of course if the damn thing works then all is good!

A a comparison stock OEM or Karl and Jeffs spacer only requires 16-27mm preload.

Hmmm, either way not so bad. How are the bikes handling guys?

OTOH, after looking at the sag numbers it's apparent near the same results can be had with either way. These adventure bikes are really a challenge due to the frequent added and removed weight. I went through the same thing with my Beta. I must have changed at least three spring rates before I got a decent sag I could live with. I still can't believe I was using it for adventure riding!!! Trust me 800 miles on a dirt bike through Death Valley was torture!!

For the heck of it here are my OEM spring sag numbers with my bike stripped and me in my riding gear. I'm right at about 220-225 lbs geared up and ready to ride. Tank is full and crash protection installed.

1 helmet: 48mm free sag/87mm rider sag

1 helmet and luggage: 46mm free/82mm rider

2 helmets: 32mm free/72mm rider

2 helmets and luggage: 29mm free/68 rider

Very similar to mine with the stock spring. The results we get with the bike stripped and in the highest setting is what we should be seeing in the lowest setting.

WJBertrand,
I'll try your vice idea on the 2012 where I can take the shock to the vice--couldn't do that with my 2014 ES.

I swapped in my race tech 9.0 today on my 2014 ES and took it around the block. initial impression is good. I will be on track with it next week so that will be the first major test, and the second will come when I next have my girl riding pillion.

A couple of observations while it’s fresh in my mind:

Its pretty easy, all shock and dogbone bolts easy to access. The hardest part is the spring compression. I used a Tusk compressor from Amazon and it was barely adequate for the job. Honestly it was just a little sketchy on the new stiffer spring.

I removed the right panel cover and couple of metal cable guides from the right subframe to make room to work.

Removing the remote reservoir from the passenger peg was necessary to give enough slack to move the shock around. It is a single hex bolt being the passenger peg bracket, the larger of three, good access. That’s all you need to detach the reservoir. I raised the rear wheel up with a strap after disconnecting the dogbones and that made it easy to drop the shock enough to wiggle it free and out the top right side of the bike.

I did the spring swap with the shock resting on the foot peg. I did not remove it from the bike as the preload connector was still attached. Juuuuust a little sketch. Don’t forget your safety squints.

Overall an easy job, took me a couple of careful hours and only one or two cusses. I’m optimistic for the result after putting around the block.

I am curious to see what you impressions are of how it handles with the 9 kg spring and stock front suspension. It makes me wonder how much it is going to increase nose dive under braking.

I really appreciate all the footwork you guys are doing for spring replacement options. I still prefer Jeffs and Karls option with a spacer and less preload. OTOH, the drop in 6022 spring seems to be working out great. My OEM spring does not cause any ill handling and the bike tracks great. What I don't like is how much it sags when putting the side stand down. Unless I have it set full stiff, the bike almost wants to tip over to the right.

I noticed in an earlier post Jeff was wondering what the seat pressures were with Karls setup that he used. I added them on to the chart as well as a couple more of the Racetech springs.

That is why I am replacing my oem spring. My bike took a tumble in June on a trip. With the bike loaded even in max preload setting of two up and bags it sags too much and the bike sits almost level on the side stand. It didn't take much of a wind gust to blow it over. As for the seat pressures: At any given sag when the weight on both bikes are the same and the sag is the same then the seat pressures are equal no matter what they were before the load was applied. All the seat pressures given above in the chart are with zero load on the shock. It is only the pressure the spring is placing on the seats for each preload setting before the wheel touches the ground. Once the bike is on the ground those numbers change. It just gives a baseline of what to estimate your sag to be before buying a spring.

Well that sucks. I just got off of the phone with Racetech and this spring is discontinued and they have none left in stock.

Sorry to hear that. I’m actually thinking of getting a set of dog bones to raise mine. Or take the bike to Race Tech and let them do their thing. The main shop in Corona has a full service machine shop to make spacers and they have spring measuring tools to get my sag set perfect.

The bike just rides so good right now! It’s only when it’s parked that causes problems.

No not with what happened with your bike. BTW what were the specs on the spacer they made for you to use with the Eibach 800 lb spring?

You need to take one for the team Chris and get your bike to RT. Having just an ES shock and and some spec sheets obviously hasn't worked out well!
Aint that the truth!! I have been by there twice and picked springs that were posted here. Neither one worked. The one that did work required so much preload it was suggested not to use it. I was told by the service manager to wait until I get some miles on the bike before bringing it in. I think they only charge about 100 bucks for each end labor for the R&R. For my dirt bikes I did suspension service every 25-50 hours when racing and now every 50-100 hours for normal trail riding. It was explained to me that under normal riding conditions full service for street oriented bikes is not due until close to 10,000 miles.


For now those rising links are looking pretty good! I think it's a good option to use until I bring my bike in for a full suspension service.

Yes it's a band aid for sure. OTOH cheap and easy. I have used dog bones in the past to lower the kids bikes. This would be a first using a shorter one to raise the bike.

I was going to put this in a PM but I cannot include pics. Here are the numbers for the 800lb spring they had on your bike with 7mm total spacers. The 800 only has 107mm travel. You run out of travel in both the 2 up and 2 up plus bag settings.

Thanks Super08. Good thing I'm not one who rides with passengers!

Hopefully all the information, including RT's failed attempts to date, will help someone develop the definitive spring solution for ES machines.
