What's the maximum displacement of a combustion engine of a moped that you can ride when you hold an AM-category driving licence?

A category AM driving licence entitles the holder to drive a moped. According to the statutory definition in the Road Traffic Act, a moped is a vehicle equipped with an internal combustion engine with a capacity not exceeding 50 cm³ and whose design limits its speed to 45 km/h. Exceeding this capacity classifies the vehicle as a motorcycle, which requires a driving licence of a higher category (e.g., A1).
