Often we get questions related to fork oil. So in this article we have tried to give detailed information regarding fork oil. Hope you get satisfactory information from here.

When an object throw on the ground, it bounces back with the same or high-low speed that is called rebound. Now attache a light object with a heavy object. Throw it again and notice how it bounce back. That is depends on what you put in it, it will bounce high, low or not bounce at all. That is call compression.

Let me give you an example, Bring a basketball. Throw it on the floor. Then notice how fast it bounces? That’s rebound. Then fill half of the basketball with water. Bounce it back to the ground. Do you see how slow it returns? That’s compression. Helium, air, water or lead change the properties of a basketball. Fork oil does the same thing for your bike. 

What does the Fork Do?

Shock absorbers include a spring that protects the vehicle against obstacles on the road. Due to bumpers and potholes on the road, shock absorbers create vibrations in the vehicle tires so that the vehicle does not bounce too much and can be driven easily. In a two-wheeled vehicle, shock absorbers are divided into “front fork” and “rear cushion”.

Role of front fork :

  • The front fork acts as a rigidity component just like a frame. Vehicle-specific stiffness that is given the current goes blank when you brake and change the direction of the wheel with a handle.
  • Maintain proper vehicle frames and the protection is straightforward and driving in the right direction.
  • The front fork prevents excessive weight on the front wheel during a very difficult braking, slowing down collisions when driving on a hard road.
  • The front fork dissolves in slow motion due to the road.

How to choose right fork oil?

No Fix Viscosity Standard

For engine safety the engine manufacturer manual recommends the specified oil viscosity. Which makes your drive comfortable by increasing the life and performance of the engine. But only engine safety is not enough for a vehicle. Vehicles on the road face many obstacles. To avoid this shock absorbers are there in vehicle. No universal viscosity standard has been set for fork oil. Each shock oil manufacturer is free to formulate its oils to whatever viscosity it deems appropriate. That means one brand’s “light” fluid could behave like another brand’s “medium” fluid, and so on. 

Stick to one fork oil

Once you have make the right choice of shock oil set with your vehicle then stick to the same brand. Folk oil is the biggest variable in tune your vehicle’s suspension. If the fork oil is changed frequently, it reduces the vehicle suspension and the confidence of your rider.

Compare viscosity at 40ºC

If you are thinking of replacing your fork oil, first compare the viscosity of the existing oil with the new oil at a temperature at 40ºC. 

Or you can check the data sheet available at manufacturer site. The closer the result comes, the better the shock oil will work.
