00180-05Y Ohlins Shock Spring 46/90/27 Ohlins Shock Spring 90/46/59/6.5/0-07B Ohlins Shock Spring 46/70/45 Ohlins Shock Spring 70/46/60/7/45/30. 1091-34/100 is an example of a code you will find on an Ohlins shock spring. Using the below charts you can “decode” what you are looking. Ohlins TTX spring rates.
Will you be using the spring on the shock, mounted to the bike, while riding? (hey, I don't judge.) Will you be riding naked or with gear on? (again, I don't judge.) You're asking the shock to perform certain functions, of which the spring is an integral component.
This is with 12 to 16 MM of preload on the spring!!!!!! Note weights are rider weight with gear, or take your weight and add 15 lbs for gear. 140-160 Lbs 80.0 Nmm 160-180 Lbs 85.0 Nmm 180-200 90.0 Nmm 200-220 95.0 Nmm 220-240 100 Nmm 240-260 105 Nmm 260-280 110 Nmm How To Read An Ohlins Spring Code 1091-34/100 is an example of a code you will find on an Ohlins shock spring. Using the below charts you can “decode” what you are looking. The 1091 refers to the diameter and the length of the spring.
Preload on the spring way of Testing and Tuning is far more accurate then trying to roll around field checking rider sag, most often done incorrectly and with worn shock and linkage joints making the measurement not as useful. ___________________________________________________________________________ Click Below for pdf sheet first things to do~ There is far too much to mention when suspension and whole motorcycles must work in harmony for best results.
The problem is almost no sag when riding alone (15mm). The rear wheel tries to come off the ground. Fully loaded is about wright with no pre-load adjustment put in. With suit on I weigh about 210. I need a heads up before I call Dan this time. I feel your pain!! You are right, the spring supplied for the standard GS is way to stiff.
You also should test with Brand New high quality new fresh tires with proper tire pressure set before each moto or ride per ½ lb increments test with expensive high quality pressure gauge or use nitrogen even better, not those old things that still show tread you had for a few months like above. Much like rear tire wear, maintain your suspension fluid through a detailed professional factory authorized service with same materials and procedures only.
The rider's preferences are ultimately what matter most. If you continue to have trouble contacting Ohlins USA send me a PM and I'll give you contact info for Mike F. I send nearly all Ohlins inquiries his way.
I'd assume that a.925 would be ur best option. Try and set up ur sag before u start changing springs tho. Well my buddy just got a shock back from Mike with a.90 spring. He weighs 155. I'm 195 and my.95 spring is pretty much in the middle of the preload range. According to that. I'd assume that a.925 would be ur best option.
I've ridden the bike 50K miles with a '150' spring. In your collective opinion, will the 170 be too stiff?
In this case the /100 means it’s a 100nm spring.

Some additional thoughts, The number we change is the Force due to that rate and preload and sag added, resulting in some big force number. As in the following: F=kdx Where F = the resulting force due to preload and sag together. 'dx' is the change in the distance from the free length the spring to compressed.
1091-34/100 is an example of a code you will find on an Ohlins shock spring. Using the below charts you can “decode” what you are looking. • The 1091 refers to the diameter and the length of the spring. Almost all Ohlins springs have a diameter of 57mm so that’s easy, the 1091 in this case means it has a 160mm length (when not on the shock) • The -34 is the spring rate. For some unknown reason Ohlins uses it’s own numbers to label rate, but below on the rate conversion chart you can cross reference this number. In this case a -34 is a 100nm or 10.19kg or 571lb spring • The /100 is the springs rate in Newton meters, but without the decimal.

When camping I also carry a 16 lb duffle. I know nothing about suspension tuning.

If it's beyond the half way mark (all in or all out), you may want to consider the next spring up or down for your preferences. No matter, the charts aren't meant as an absolute.

I'm looking at Ohlins spring chart and I am confused. It doesn't say if the weight in the chart is just for rider weight, or rider weight with gear. Can you advise please? Will you be using the spring on the shock, mounted to the bike, while riding? (hey, I don't judge.) Will you be riding naked or with gear on?
Try and set up ur sag before u start changing springs tho.You missed my inside joke about the decimal points. A.925 spring would still be soft for the rear To view links or images in this forum your post count must be 5 or greater.
The springs are setup in very closely set ranges. If you look at the first post in the thread you posted in yesterday, they show where one spring rate ends, the next starts. Typically, depending on weight, it may very well be possible to use one of about three different springs. The real determining factor will be if you can get the starting sag number. Then, depending on riding characteristics, rider preferences, available external preload etc; you may find yourself altering the spring rate slightly during the next service interval. So with you starting with the 100 spring, I would set the sag and run the heck out of it. When you get close to needing service, make note of the amount of preload used to get you in your desired range.
Or both that and add some heat, (that old lowering the car trick form the fifties). Still this will simply shorten the overall length of the spring the rate is constant, (Unless you use heat, then all bets are off which is why that method of dropping a car was a bit hit or miss). Or for all practical purposes a constant. There is a bit of non-linerarity but the affects of that are small, thrid order or so, has to do with damping in the spring itself.
Searching around I see one rider has a 59/150/257 and another has a 39/110 L213. The problem is almost no sag when riding alone (15mm).
The first time we determined I needed a softer spring. I did not see much if any difference. The spring I have is a 00698-64/160 L476. Searching around I see one rider has a 59/150/257 and another has a 39/110 L213. The problem is almost no sag when riding alone (15mm).

If I remember correctly It has been a while since I messed with this stuff. What feel like spring rate change in a coil-over shock system is not the spring rate changing but more likely the compression damping changing. This rate can and does change along with the rebound damping rate over use and time as these are a function of the states of the oil, seals, and charging gas. It should be fairly simple calculation to find the close-enough spring rate as a function of sag. Fun too.:huh I think it will require some paper, a pencil, camera measuring tape, then a computer and some alcohol. You know to keep everything clean. So, is everyone ready for their homework?

Dan is wrong about this issue.I've reduced the rebound damping to acceptable levels and it helped. Oddly my 1200GSA with Olins is perfect but I have a more sophisticated shock on it. 1200gs with olins from Dan Kyle Racing.

Dan Kyle 1098 Shock Spring Recommendations NOTE!!!!!
I got my Ohlins shock straight from distributor in NC and they were supposed to set the shock spring to my weight. I just wanted to make sure if it's the right one before I install it on the bike.
But as Dan alluded to, think but don't over-think, sometimes you have to go ride the thing. Research is a good thing but all the fun stuff happens in the lab. Have fun riding. I would think that either the 100 or the 105 (very minimal difference) would work for your weight range. The springs are setup in very closely set ranges. If you look at the first post in the thread you posted in yesterday, they show where one spring rate ends, the next starts.
These numbers are for the standard GS and not the adventure. I feel your pain!! You are right, the spring supplied for the standard GS is way to stiff. I'm 170lbs and the 130 sping allows for almost no sag statically. I took my shock to Dan so I could reduce the pre load(you have to dismantle it to do so). Even with the preload backed all the way off its still to stiff.

The guys at Ted Porter's BeemerShop are recommending a '170' rear spring for my '07 R1200GS. It has BMW adventure cases on it at all times. Empty when I commute they weigh 15 lbs each and 25 lbs each when I'm camping. When camping I also carry a 16 lb duffle. I know nothing about suspension tuning.

That’s some of the reason why a spring number is only a number in overall feel. (See below TECH for Sample Program Sheet) 4) Above pic shows Primary Spring and Compressed Top out Spring Relationship which effect initial feel and front true preload calculations.

Here is what I know. Assuming the Ohlins spring rates have stayed the same since 2005.
I told them I weight 220lbs with gear and ride 80% track - 20% street and they got me this spring - 21040-34/100 (TTX GP shock) I am looking at those charts to make sure and can't really understand them DanQ can you please advise me if the spring is right for me? I've been told by others many times that you are a master in suspension stuff. I have called Ohlins, but nobody is picking up the phone, also sent them an email with same question, but I haven't received any response yet (2 days). I got my Ohlins shock straight from distributor in NC and they were supposed to set the shock spring to my weight. I just wanted to make sure if it's the right one before I install it on the bike.

Superbike Supply. I gave them the weight and it came with the.90, but a buddy thought it was too soft so he called Thermosman and he said it may be too soft. I'm hoping ur right though, don't really want to send it back out for a diff spring.Well my buddy just got a shock back from Mike with a.90 spring. He weighs 155. I'm 195 and my.95 spring is pretty much in the middle of the preload range. According to that.
4) “Rider Sag is so 20 years ago”, with the quality of springs these days, a much more important measurement is Free Length minus installed Length = Spring preload. Based on your rider info most are 10mm to 14.5mm of spring preload (some exceptions can vary). For the first several weeks of use, Only experiment as needed by 1/8 spring turn more or less, No Crazy full turns ride by feel, don’t chase Rider Sag numbers. You can ball park a rider sag number to generally be 30-33% of claimed travel (ie 90-120mm ) but since most can’t measure correctly, don’t beat yourself up over it, when most try 98mm-112mm with 15mm-35m bike sag (“oh my @ what is that / i told you you didn’t no how to read a ruler”). 5) Your bike is much like this. A see-saw so an example is that a subtle nudge spring only 1/8 turn or less on rear can affect front.
For your Weight and Conditions there are many Springs for many things- Most brand new shocks we sell will have the best spring choice determined and preload given your information you provide. There is years of great current data with many others that weigh the same as you, and or have loading or conditions the same as you, so it’s very easy on new shocks or forks when ordered. On some new year model or preowned suspension that you may have you may need to determine more below, and many personal preferences can still apply.
