What fork oil should I use?
Look for a high-VI fork oil Instead, look for a fork oil with a high viscosity index (VI). A higher VI indicates better resistance to viscosity changes throughout broad temperature swings.
How important is fork oil?
The fork is a vital component of the ride quality of your motorcycle. Inside each fork is valving that controls the compression and rebound of the fork going up and down, or in and out. The fork oil inside the fork works directly with the valves to provide consistent damping when you’re riding.
Does fork oil weight matter?
Heavier oil will increase the effective damping, in other words the forks will move up and down a little slower and feel stiffer. Lighter weight oil will do the opposite, allowing the forks to move up and down faster and feel softer.
Can I use ATF instead of fork oil?
ATF works great as a fork oil. It is relatively light weight, 2-5 W and rather unpredictable. If you need to use more than 1 bottle it might be a good idea to premix the stuff to isolate any bottle to bottle differences.
What viscosity is ATF fluid?
ATF III – Mineral automatic transmission fluid
| Temp. [°C] | Dyn. Viscosity [mPa.s] | Kin. Viscosity [mm²/s] |
|---|---|---|
| 0 | 217.29 | 247.39 |
| 10 | 118.06 | 135.42 |
| 20 | 70.04 | 80.93 |
