Suspension oil weight chart
There is a lot of confusion about the suspension oil to use in our front forks or shock absorbers. So, to facilitate the searching, we have made a Suspension oil equivalence chart for you.
Now you can compare quickly suspension oils by brand.
SAE range
Despite what many believe, the SAE range does not define the exact viscosity of an oil. It is a reference to a range of viscosities in which it can be contained.
Therefore, the SAE range is more appropriate for use in motor oils rather than for suspensions. Keep in mind that each manufacturer places its oils where they think it should be (it’s not a standard).
In addition, what can cause when changing the oil brand while maintaining the SAE, is that your suspension (being a front fork or shock absorber) behaves in a different way (because the kinematic viscosity is different).
And in a 99% of cases, doesn’t perform better than before.
General recommendations
We recommend using the original oil on your suspensions so that the damping behavior is not changed.
In case you can’t find the original oil, use the one with the closest kinematic viscosity.
You can look up for the original oil specs in the workshop manual or by asking to an official dealer.
You can also look up for it on internet forums, although it may take longer.
Viscosity or density?
The viscosity is measured in centistokes (cSt) or mm2/s at 40ºC as a reference temperature and is a technical characteristic of each oil.
Viscosity index indicates the “quality” of the oil. The greater the number, the more stable the viscosity is against temperature changes.
Therefore, it is important to remember that the viscosity of a fluid (resistance offered by a liquid to flow) has nothing to do with its density (mass per unit volume).
Suspension oil equivalence chart
Below you can find a equivalence suspension oil chart (both for motorcycle and bicycle) where you can easily choose the closest oil to the original one.
Oils are sorted by Viscosity. SAE range is only shown for your reference.
If you can’t find the same viscosity as your original oil has, choose one with a difference of +/- 5cst. Beyond that, the damping behaviour is quite different.
A change on oil’s viscosity could need a new damping adjuster (low speed adjusters COMP/TEN) set-up.
Example
Original oil was a 14,14cst. Couldn’t find nothing else than a 15.3cst oil. This means that all damping (compression and rebound) will be slower, in general.
Turn the external adjusters 1 click/1/8turn anti-clockwise.
This doesn’t means that suspension behaves exactly the same as with 14,14cst oil, but slow speed behaviour is similar.
The bigger the difference in viscosity from the original oil, the more turns/clicks would need the adjuster.

Hello, could it be possible to add the Liqui Moly fork oil range? Regards
Hi Fernando,
The Liqui Moly suspension oils have been added to the list.
Thanks!
Could you add the Nitron 02 fork oil?
Hi Ed!
Job done! Nitron 02 included in the chart.
Regards!
Can you add the YSS 10w to the list? Thanks!
Hi Michael,
We couldn’t find YSS suspension oils anywhere.
Do you have a link to them?
Regards
Please can you add Repsol Qualifier: https://lubricants.repsol.com/content/dam/repsol-corporate/en_gb/productos-y-servicios/lubricantes-documentos/qualifier-fork-oil-5w-10w-en.pdf
Hello, can you add KYB K2C and if possible old KYB 01?
Hi Calvin,
Added those couple of KYB oils to the list.
Thanks!
Just verified that Putoline HPX R 15W is not 66,80 but 62,70 and Putoline HPX R 20W is not 99,40 but 94,50! Did they changed that over time, or this is a mistake? https://www.putoline.com/en/catalogue/maintenance/
Hi!
We always take the viscosity from manufacturer website or Material Safety Data Sheet, what’s available. We have found on several manufacturers that they slightly change the kinematic viscosity of their products, as in the example of Putoline. This can be by an oil supplier change or additive packages change (by any possible reason). We will check the Putoline range as 4cst is a big difference in viscosity for a product labeled with the same name. Thanks mate!
Hi
I am in Iceland and the average temperature is around 10C° in the summer and 3,75C° for the hole year. my bike should use 4W now I am using Motul 5W (4W is not available in Iceland) and I think it is to firm.
If I go down to Motul 2,5W will that compensate for this low temperature here in Iceland.
Temperature effect on oil.
Hi Kristbjorn!
True, oil viscosity varies according to temperature. Frankly speaking, I have never thought on changing the oil spec for extreme conditions, thanks for pointing that out.
In your case, check the original oil viscosity in cst’s and lower it 5 to 8 cst’s.
For example, if the suggested oil by the manufacturer is 19cst@20°C, go to 14cst as a starting point.
Don’t rely on the weight shown in the oil’s bottle because as you can see in the chart, it has no relation between brands.
Hope this helps!
Hello, can You add Honda/Showa SS-55 oil? Honda CBR 600RR 2005 front fork.
Hi Michal!
I have never seen the SS-55 oil and neither can find any reference to it. I looked on Showa’s Safety Data Sheets and this oil doesn’t appear (or I was unable to find it).
This Showa fork was used by other manufacturers, and although they were using different shim stacks, they were not using SS-55.
Do you have the service manual to check the exact oil it is using?
Hi again Michal,
I could find it, but it’s branded by Honda (not Showa), that’s why I was lost.
It is somewhere between 30 and 35cst @40 Celsius.
Look in the chart for something in between those numbers.
Will add it to the chart when I find the exact cst’s.
Regards!
