You have fitted your motorbike with a tank bag and side panniers. What must you ensure?

Your answer is completely correct. When fitting additional luggage like a tank bag and side panniers on a motorbike, German traffic rules require you to consider weight and handling to ensure safety. First, you must never exceed the gross vehicle weight rating, which is the maximum safe weight specified by the manufacturer. Exceeding this limit can affect braking and stability. Second, with increased load, the tyre inflation pressure should be raised accordingly to maintain proper grip and reduce wear. Third, the rear wheel suspension should be adjusted if necessary to handle the additional weight, ensuring proper balance and ride comfort. Neglecting these adjustments can make the motorcycle unstable and unsafe to ride. Keeping these factors in mind helps maintain safe handling and legal compliance.
