What documents must you carry with you, if you want to drive a motorbike with an engine size larger than 200 cm³?

The combination of documents you selected is correct because, according to German traffic regulations, when riding a motorbike with an engine size larger than 200 cm³, it is mandatory to carry both your driving licence and the registration certificate Part I.

The driving licence is necessary to legally operate the motor vehicle, ensuring that you have the required training and authorization to drive. The registration certificate Part I serves as proof of the vehicle's registration and ownership, which is important for legal and identification purposes on the road.

The registration certificate Part II is not required for riding; it mainly pertains to the ownership of the vehicle and is not something you need to present while driving. Understanding which documents are necessary helps ensure compliance with traffic laws and avoids potential fines or legal issues.
