What is one of the risks associated with riding with a passenger?

Riding with a passenger introduces changes in balance and handling because the additional weight and shifting movements of the passenger can affect the motorcycle's dynamics. This alteration in balance requires the rider to adjust their riding skills and adjust to the new handling characteristics of the motorcycle. The added weight can impact acceleration, braking distances, and cornering capabilities, meaning the rider has to be more vigilant and aware of how their motorcycle responds.

For instance, when leaning into a turn, both the rider and passenger must shift their weight correctly to maintain balance and control. If the passenger is not properly positioned or does not understand how to lean with the motorcycle, it can lead to instability and an increased risk of losing control.

In contrast, the other options suggest benefits or features (like improved stability, increased speed, and enhanced visibility) that do not accurately reflect the challenges and risks introduced by having a passenger on the motorcycle.
