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).Ĭheck the next video to learn more about the importance of visosity (and suscribe to our channel!)īelow 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. The greater the number, the more stable the viscosity is against temperature changes. Viscosity index indicates the “quality” of the oil. The viscosity is measured in centistokes (cSt) or mm2/s at 40✬ as a reference temperature and is a technical characteristic of each oil. You can also look up for it on internet forums, although it may take longer. You can look up for the original oil specs in the workshop manual or by asking to an official dealer. In case you can’t find the original oil, use the one with the closest kinematic viscosity. We recommend using the original oil on your suspensions so that the damping behavior is not changed.
