What kind of oil is used in motorcycle forks?

There are several possibilities. Some motorcycle manufacturers recommend a certain kind of oil or fluid for the telescopic front forks of their motorcycles. Among motorcycle riders the opinions as to what is best varies. You can use clutch and brake fluid for the shocks. This has the advantage of being long lasting but will damage paintwork if spilled, so the area has to be carefully cleaned with soap water to prevent it after you pour the fluid into the shocks. You can use automatic Transmission Fluid, also. Third, you can use any thin engine or machine lubricating oil, usually 5 W, 10 W or 15 W. In addition, there are companies that produce or distribute shock absorber oil according to various specifications, such as for use in racing bikes. The cheapest solution is to use light oil, for example 10 W, as this will go in most front forks and works out well for the average driver. Brake and clutch fluid has the disadvantage that it is more expensive and more difficult to handle.
