Once you have considered all of these factors, you should be able to narrow down your choices and find the perfect motorcycle fork oil for your bike. For that reason, it’s best to do some research to find the right one for your motorcycle. Some brands provide better products than others. You can find different brands on the market, each with its formula. Fork Oil Brandīefore purchasing a fork oil, consider the brand is very important. Normally, the higher the number, the more compatible the oil. It’s because it offers a measure of how consistent the oil’s viscosity is across a temperature range. What you need to look for is the viscosity index.

That’s why choosing the right one can be more difficult. For example, a 5W or 7W fork oil may be thicker than a 10W or 15W fork oil. With many different viscosities, you can end up of the same weight and even high viscosities at low weights. The first number indicates winter weight and the second number indicates summer weight.įork oil weight and viscosity don’t always line up. Well, these numbers indicate that weight means how thin or thick the oil is. Fork Oil WeightĪccordingly, you have seen the numbers like motorcycle fork oil 20w, 5w-30, and 10w-40 on motor oil containers. As a result, it produces less damping force. Generally, this is a thinner liquid that travels freely through the valve. In addition, the opposite of low viscosity is fork oil. It takes additional force to get fork oil through the fork valve holes. So, if the viscosity is higher, the damp you get. If fork oil viscosity is higher, the fork oil flows slowly. The oil density will generally determine how well your fork performs and how comfortable your ride is.įork oil thickness is a measure of viscosity or how resistant it is to fluid flow. When you are talking about fork oil, density is one of the most important factors to consider. Here are some points you should consider, before purchasing a fork oil. Additionally, it does this regardless of terrain, temperature, or what type of motorcycle you want to ride. It controls the power of the fork and converts it into heat that the fork absorbs oil. The oil inside the fork works directly with the valves to provide consistent damping as you ride. Inside the fork, oil operates directly with the valves to offer compatible damping when you ride. Two movements are involved: in and out or going up and down. Inside each fork is a valve that handles fork compression and rebound.

The fork is an important component of your motorcycle’s ride quality.
