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

The selected combination is correct because all three points are essential for safe operation of a motorbike with additional luggage.

1. Exceeding the gross vehicle weight rating can lead to reduced control and increased stopping distances, which is a safety hazard. German traffic regulations emphasize adherence to weight limits to maintain vehicle performance.

2. Adjusting the tyre inflation pressure is critical when the load increases. Under-inflated tyres can lead to poor handling and increased tire wear, while over-inflated tyres can reduce grip.

3. Adjusting the rear wheel suspension helps maintain the correct ride height and handling characteristics. A properly adjusted suspension is crucial for ensuring stability and comfort while riding, especially with added cargo.

All three considerations ensure safety, stability, and compliance with traffic laws, which is vital for responsible motorcycle operation.
