When is there a risk that the front wheel of the motorbike will lose contact with the carriageway?

The combination of accelerating in a low gear and accelerating while carrying a pillion passenger poses a risk of the front wheel of the motorbike losing contact with the carriageway.

When accelerating in a low gear, the torque is higher, which can lead to a sudden lift of the front wheel, especially if acceleration is aggressive. Additionally, carrying a pillion passenger adds extra weight to the bike's rear, changing its balance and dynamics. This can also contribute to the front wheel losing grip, especially when combined with rapid acceleration.

Braking using only the front-wheel brake, while it is a common practice, does not create a risk of losing contact with the ground in the same way that accelerating under the conditions described does. Instead, it can lead to a loss of control or a possible wheel lock-up, but it's not directly related to the front wheel leaving the carriageway.

Understanding these dynamics is crucial for safe riding and is emphasized in German traffic regulations, which aim to minimize the risks associated with motorbike operation. Recognizing all relevant factors in a multiple-choice context helps ensure that riders are equipped with the knowledge to navigate various situations safely.
