Ohlins Spring Chart Pdf

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. 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.

Use the charts below to help you establish the best spring rate for your Demo/Enduro EVO. Ohlins rear shock spring rate guide Author. Feb 26, 2015 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.

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. Get the next lowest spring rate! Dan is wrong about this issue.I've reduced the rebound damping to acceptable levels and it helped.

Have fun riding. Thank you guys!! Order the springs that match your weight (without gear is what I go by personally) hmm, interesting!

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.

You know to keep everything clean. So, is everyone ready for their homework? Remember to show your work, and remember units are important! I have never measured the sag on my bike. In 2009 I weighed 195 lbs. Today I weigh 220 without a helmet.

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. 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. He's an Ohlins guru with few equals. Will you be using the spring on the shock, mounted to the bike, while riding?

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. 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.

Many modern forks with a.52N/m may feel plusher than a fork with a.48kg, (don’t be too stuck on just because you used a.43kg in the mid 1990’s your current machine needs that number) Its getting popular to also field check front rider sag also, it’s a lot harder to do than the rear but possible to do the front spring preload and spring rate calculation. To be most accurate you would need to minimize seal and bushing stiction, fork angle, and other possible alignment issues. There is a specific program for this but the basic idea is to also consider if an internal top out spring is used and what rate that top out spring is within the cartridge or strut and how it actually can effect the actual spring preload. 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. 5) 6) 7) 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. 8) Shown above blue arrow is New style 2016+ Ohlins TTX shock spanner with “notch” for spring end.

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.

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. 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.

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.

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. Typically, depending on weight, it may very well be possible to use one of about three different springs.

1) For a Quick ballpark (D.I.Y.) info follow these- Shock Spring A,B,C’s. Simply put, to have the correct balance you need to have the: A) correct spring rate* B) correct range of preload on that spring choice* C) to get you the correct rider sag* and bike only sag with no rider.

(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. What is the weight that will be acting on the spring? 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.

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.

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.

That is unless the spring somehow loses its temper, or is compressed beyond its elastic limit. About the only way I guess to do this would be to compress the springs to coil-bind, (coils compressed such that they touch), and then leave them there for a very long time. 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).

The easiest way to check your sag plus this one fits in your tool box drawer, KEEP in MIND that “Spring Preload” is AS or MORE IMPORTANT than JUST Rider SAG. (see Below Pic 7+) Metric whole numbers is the way of the suspension world! Or “inches” if your bike is made out of Wood, maybe run the other way if your suspension guy uses “inches” these days!.

Dan Kyle 1098 Shock Spring Recommendations NOTE!!!!! 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.

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. In this case the /100 means it’s a 100nm spring.

Or a spring “RATE” change may be helpful. Many things feel weird if your off on this, the rear effects the front and front can effect the rear, the travel may feel lifeless or too stout, the turn in or balance may be to lazy or too steep.

He weighs 155. I'm 195 and my.95 spring is pretty much in the middle of the preload range. According to that.

1200gs with olins from Dan Kyle Racing. Am about to send in the rear shock for a second time. 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).

Get the next lowest spring rate! 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. Am about to send in the rear shock for a second time.

In similar fashion to most online tyre wear charts, spring rate charts are good starting points, but they are nowhere near being the absolute answer to every problem. My personal opinion is that they are overrated.

Oddly my 1200GSA with Olins is perfect but I have a more sophisticated shock on it. How to update amd radeon drivers windows 10. Here is what I know.

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.

'dx' is the change in the distance from the free length the spring to compressed. 'k' is the spring rate from above, that 571 lbf/in of deflection. Also in a steel compression spring you are going to be hard pressed to change this spring rate.

A component education seminar may do you great service at any price, call for details in season, a daily 4 hrs training and consultation from $1500.00 and up. Suggestions start here, 1) Do above to forks fully extended off ground, equalize air build up prior to each ride.

Once within manufacturers range, tuner’s often add or take away a little as ONLY a half turn at a time more or less slight turns to further benefit their use. A) You can exactly measure the free length of the spring usually in (mm) while off shock. B) Installed on shock which is slightly compressed example maybe 10mm to 16mm of “Preload” depending on what its going on. C) Then once all back together field check with some pretty exact measurements of “rider sag” meaning fully suited up with about 2/3 to 1/2 fuel load which in general terms rider sag is settle from fully extended total travel there is to get started, while staying in the “preload range” listed in step “B” above, and after that is set, the “bike only” or “static” sag should be about 5% -10% of that total travel claimed, or buy some springs! They are only as accurate as your measuring skills, body placement and free play in shock mount bearings. All of those above things are then considered, Visit Our TECH-TOOLs-PICs page for more info on Accurate Spring Rating and Testing and How to determine Preload. 2) 3) Surprisingly we found even major suspension companies and publications not informing their customers about the difference between N/mm and Kg/mm.

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.
