What is a significant risk when riding over gravel?

Riding over gravel presents a significant risk of loss of traction and control due to the loose surface material. Gravel does not provide the same level of grip that solid pavement does, which can lead to skidding or sliding, especially when turning or braking. This loss of traction can be particularly dangerous for motorcyclists, as it may result in difficulty maintaining stability or an increased chance of falling.

In contrast, decreased engine performance, increased fuel consumption, and heightened visibility issues are not direct consequences of riding on a gravel surface. While they may impact overall riding experience under different conditions, the primary concern in this scenario revolves around traction and control, making it essential for riders to navigate gravel with heightened caution to ensure their safety.
