Typical costs for an advanced driving test in EU countries are:
180-250€ basic fee of the driving school
100-150€ driving school exam fee
50-60€ practice hour before exam with driving school motorcycle
130€ examination fees to an authority
35€ processing fee to the respective district office
I.e. you have to pay 450-600€ for an exam, which you already passed identically two years before!
There are no exercises or adjustments made to the fact that the "new" motorcycle has more power.
This makes the EU motorcycle driving license upgrade tests nothing more than chicanery for learner drivers and a money printing machine for driving schools.
Due to the extremely regulated market of authorized driving schools, they can thus charge the ridiculously high fees without losing students to the lack of competition.
