How much oil should be put in a hydraulic EBR new model front fork?

EBR hydraulic front fork Tomos

Hydraulic EBR front forks were used on various Tomos models such as the Tomos Classic, Flexer, Roadie, Quadro but also the Tomos Revival and Streetmate, both for use with a brake anchor plate and brake disc.

These front forks are hydraulically sprung and thus contain hydraulic front fork oil. Each inner leg contains 100cm3 of oil and is sealed by a retaining ring. Oil can easily be drained through the bolt at the bottom of each leg. 

Please note that not every new model front fork contains oil! There is also a suspension version.

For these EBR front forks, we use hydraulic oil from Eurol
