Silkolene gaffelolja 30W heavy

A fork oil is subjected to a very wide range of temperatures, even in normal touring use. In order to provide a consistently smooth fork action at all times, with optimum damping qualities, Silkolene Fork Oils are based on high viscosity index oils to ensure minimal viscosity change throughout the operating temperature range.

The SAE figures give a good guide to relative oil viscosities, however, the ISO figures, related to the true viscosity at 40°C, give a more accurate assessment of damping capabilities.
