You are holding a driving permit class A1. Which of the vehicles described are you allowed to drive?

With a class A1 driving permit in Germany, you are allowed to drive motorcycles with a maximum capacity of 125 cm³, a maximum power of 11 kW, and a power-to-weight ratio not exceeding 0.1 kW/kg.

In this question, only the vehicle described in answer 1 fits these requirements: it has a capacity of 120 cm³ (under 125 cm³) and power of 11 kW (meets the maximum limit). The other vehicles either exceed the power limit or engine capacity allowed for class A1.

Whenever you answer questions about license classes, check that both engine size and power fit within the limits for the specific class, not just one of the criteria.
