I just wanted to give a big shout out and thank you to Karl for his research and effort for this very simple solution. I'm 200lbs on the nose and 6ft. Wjbertrand had a mini tech day at his place today and we we're able to swap my rear spring with the summit racing 550 and Karl's adaptor (had a guy at my work make one out of a 5in round stock aluminum).

All I can say is WOW...the rear end is very planted now. No more pogoing over hard pavement transitions and those mid turn bumps aren't scary anymore.

Happy for you and also jealous.

I still trying to figure out what to do with my ST and 240lbs.

Have you already performed the swap and it's not working for you or you haven't done it?

I think WJBertrand is 250lbs and this mage a huge difference for him also...

Not done yet.
I have too many different opinions about replacing the shock and Im not sure which option woul be best.

If you're able to make/get Karl's spacer this setup seems to work well for 200 - 250lb riders.

Super happy on my 200 mile ride back to San Diego last night. My buddy at work made mine (and I think Jeff had a similar deal). Ordered the 550lb spring from Summit Racing.

One thing we learned yesterday was to be mindful of the collar at the top of the shock, it's keyed with a a small pin to keep it from twisting and the pin dropped out when reinstalling the spring. We munched mine and had to pull it back apart. Easy to solve as Jeff found a nail that was the same size diameter that we just cut to size.

Anyway, this is an easy job. Now that I've seen it I can do it.

I bought enough stock to make 4 more of Karl's spacers. I figured it was better to give them to my friend in case he messed up (he's new to fabricating, but he's super smart and got it right the first time). If he has time he mentioned cranking out the rest. Since he did it as a favor, I'm not going to push him to make them...if he gets around to it I'll offer them up here.

One thing to note was that my friend mentioned using round stock vs block made things quite easy for him. I was able to have the place I purchase the stock from cut it to the right size in one dimension which I think saved him time. They did this for free for me.

Total cost in materials (not including any labor) was about $86 (Spring was $66 and it was about $20 for the adapter material).

Wish I had done this a long time ago...it's a completely new bike now!

Mine is back and the sag numbers are dead on.

65mm when set to solo w/o luggage. Sag range over the four standard settings is 21mm. No error messages probably because I set the shock to 1up, no luggage before removing it this time around. The servo adjusted to all four settings without incident.

The new spring is 851lbs. (SRSP 5815152). Stoltec used an 850 lb. spring for my gen1 bike and it works well.

The new collar they installed is 75mm long and concerned me when I first saw it. A discussion with one of the technicians at RT helped me understand that the ES shock only has an 89mm stroke. The installed spring compresses to 120mm before binding, so there is no issue.



It was about 20 here this morning, and the weather doesn't look great for the rest of the week. I'll update with riding impressions as soon as I can get out.
Bringing up this old thread as a warning to anyone who decides to modify their bike shock with these part numbers.

The spring and spacer posted by regulator will not work on a ES bike.

The Part # SPSC 56526075 spacer and SRSP 5815152 spring measure out at 227mm free length

In order to get it to fit on the shock you have to compress it 30mm at minimum preload. Maximum preload is another 11mm. So we are talking 41mm preload on a 89mm stroke shock.

The spring will bind at 120mm. At 130mm spring travel the coils will hit. I discussed this with the service department at Race Tech. I mentioned that there should be no more than 5-7mm of preload on shock at the lowest preload setting and they agreed.

I imagine regulators 75mm spacer was machined down closer to 52mm to get correct sag and safe spring preload.

This is why I decided to run stock for now. I will be taking my whole bike into the shop and let them do the work after I get about 2 seasons or 10,000 miles or so on the clock.

Hope this helps....

Ironically, my ES shock and forks are at Race Tech for service as we speak. Chris and I spoke and we're in touch with RT. I'll update when we know more.

Right on Ed!! Thanks for double checking. It's really good to know these Super Tenere's are getting ridden some mega miles!! Thanks for keeping us updated on your suspension setup. Race Tech is a fantastic company to work with regarding anything suspension street or dirt. It's a huge state of the art facility with very savvy tech's.....

Hi there Ed, what's the word on your suspension?

Nothing yet Chris. Shock and forks still at RT.

Have you been there with your Tenere yet?
Yes I was. After discussing my re-spring options, The service tech recommended for me to put a good few seasons on the stock suspension then bring it in. Both front and rear are fully rebuildable. He was not sure the rear shock could be re-valved though. Please keep us posted on your results. Hopefully you can get some measurements off your rear spring and spacer.

The SPSC 56526075 spacer and SRSP 5815152 spring just won't work on my shock. It takes way too much preload to even fit and the spring will bind.

Chris, I read your posts above. What is your opinion of the Race Tech SRSP 6022 series spring that I and some others have fit? No spacer needed as it is a not perfect but seemingly "direct fit". I'm out of the dirt anymore and haven't bottomed it out on the street. Seems fine..... Comments? http://www.racetech.com/page/title/SRSP-RT%20Shock%20Spring%20List

A fellow forum member friend had this problem with Race Tech when ordering a spring for his 15 ES. They spec'ed that 5815152 spring, even though he repeatedly told them it was for an ES, not a standard. They sent it and he fit it with their spacer and it was incredibly stiff. That is listed as a 851 lb/in, which would be fine for a standard, but not an ES. Once he figured it out, he got a 476 lb/in spring and all is well.

Heck I had no idea the SRSP 6022 was a direct fit spring for the ES model. How much do you weigh and what are the sag measurements?

LOL "I'm out of the dirt anymore" as well on this bike. I'm thinking it will be used for not much more than forest service roads. Just a simple tip over in my driveway tweaked the peg mount and bent the pin holding the peg. It took me over 2 hours and a damn die grinder, welder to repair it. I can see this being a expensive bike to repair when taken in the rocks and sand and tipped over.

Chris -


I and others have dropped these bikes more than once or thrice, both on road and off, and I've been on the Tenere forums as both member since the beginning and moderator for the last couple of years. I'm absolutely not putting your comment down in any way or dismissing what happened but yours is the one and only which I've heard of breaking the peg mount.

Here is the link to the thread http://www.yamahasupertenere.com/index.php?topic=19121.0 my weights and sag as of last year with only a few miles on the spring are listed. Last check was 67 mm and I have a LOT of weight on the bike just considering the armor and top box with daily stuff. I don't believe any of the spring rate calculators really take that into account for ADV type bikes. We always have extra crash bars, skid plates etc and that stuff adds up quick. It all adds to "rider sag". The "direct replacement spring" method is quick and easy but the springs are more expensive than using the springs from say Summit Racing with the collar. Check out the link I put out to compare all their rear springs including the ones on Regulator's build. I was most interested in your assessment of spring binding and travel before binding. The "direct replacement spring" is a bit longer at 222mm. As I believe I've mentioned before Race Tech is CLUELESS as to the Tenere ES and will give you bad information. In looking at Regulator's build list sheet from them I can't imagine what went on with the front springs either. Doesn't seem to match up with factory specs in any fashion but what do I know.....

Well part of the reason is I have those huge IMS ADV II pegs. I might want to explain better. The peg mount and pin bent. I was able straighten the mount. I had to cut through the peg, pin and spring to remove it. I then had to build up peg with weld material and file it. Major pain in the rear for sure!!

Sorry for the slow response. I finally got the suspension back last month and got a chance to put it through some paces last week.


Race Tech replaced my Gen2 spring with an Eibach 0800.250.0800 and a small shim collar to allow for the spring diameter difference. They admitted that the previous installation was not correct and feel that the Eibach is the best solution, given what is currently available. After a 1,000 mile trip, both on an off road, this setup feels better than its predecessor. Frankly, I’m not convinced it is as good as the Penske setup on my Gen1, but time will tell.

Race Tech was helpful throughout the process. They claim that my ST is the only Gen2 they’ve ever worked on in their shop and now realize that the RT suspension database is not correct for the ES. They plan to update it with new information but were not forthcoming when it will be available to the public. My impression is that the sales numbers of the ES aren’t sufficient to make it a priority.

I wish my understanding of suspension allowed me to better discuss the options and help others make a decision about the best solution for them. I don’t know if this is the best and/or final RT solution for the ES. If in the market today, I’d just purchase a non-ES model and upgrade to Penske. I know the stock ES suspension doesn’t work well for me and know I can easily set up the standard model using Penske to work for my size (195 lb.) and needs.

To reduce any confusion to those reading through the thread, the current (third try) setup is:

FRST3755 .88kg fork springs
Eibach 0800.250.0800 shock spring
RT gold valving for both shock and forks

I’m hugely thankful to those here with more suspension knowledge than me. I liberally cut and pasted parts of this thread with insights offered by other members in a long letter to RT that detailed my perceptions of the second setup they sent me (not good). I believe RT is trying their best given what they have (no bike to do actual tests and very limited information) and hope that together we can develop a solution that works well for everyone interested.

They sure seem to go for a stiff ride. 800 lb is almost double what stock was. I was going to go with the direct fit spring but found out this morning they have been discontinued so now using the spacer seems to be the only option.
