What type of weather can significantly affect motorcycle handling?

Rainy or wet conditions significantly affect motorcycle handling primarily due to the reduced traction on the road surface. When it rains, the water mixes with oils and debris on the pavement, creating a slippery layer that can cause tires to lose grip, especially during the initial stages of rainfall. This can lead to decreased control of the motorcycle, making it more difficult to accelerate, brake, and corner safely.

Additionally, wet conditions can result in longer stopping distances, increased risk of hydroplaning, and a greater likelihood of skidding if a rider engages in aggressive maneuvers or rapid changes in speed. Understanding how to handle your motorcycle in these conditions—such as reducing speed and increasing following distances—can help ensure safety.

While the other options mention weather conditions that may pose challenges for a rider, such as cold temperatures potentially affecting tire performance or fog affecting visibility, none have the same immediate and pronounced effect on traction and handling as rainy or wet conditions do.
