Over the years, Tomos has used different front forks, mostly from the manufacturer EBR. With these front forks, we talk about old and new model front forks.
The old model front forks are sprung by a long spring and contain no oil. The new model front forks can be hydraulically sprung and therefore contain hydraulic oil, but also some are also sprung by a long spring and contain no oil.
The headsets of these front forks are the same, so you can interchange the front forks. If you want to convert from old to new model, don't forget to use a longer wheel axle, stabilizer bracket and mudguard.

How much oil should be put in a hydraulic EBR new model front fork?
Each inner leg contains 100cm3 of oil and is enclosed by a retaining ring. Oil can be drained easily through the bolt at the bottom of each leg.
