Who are they? Aircraft technicians or???

[Theodor]

Hi,

Got this today, at first glimpse I thought they are a training group of military motorcyclist or something like this. But reading more carefully, now I think they might be in fact aircraft engine technicians? Please, given the sign they hold, can someone shed more light who these gents are? Thanks!

To make it easier, here is the text from closer:
