A rear wheel skid on a motorcycle can be caused by several factors, primarily related to the loss of traction between the tire and the road surface. Here are some common causes of rear wheel skids:
Overbraking: Applying excessive or abrupt rear brake pressure can cause the rear wheel to lock up and skid. This can occur if the rider squeezes the rear brake lever too hard or suddenly without modulating the pressure. The loss of traction leads to the skid.
Acceleration on Low Traction Surfaces: When the road surface has low traction, such as wet or icy conditions, excessive acceleration or a sudden throttle input can cause the rear wheel to lose traction and skid. The torque generated by the engine overwhelms the grip between the tire and the road.
Cornering Too Fast: Taking a turn at a high speed, especially if combined with excessive braking or sudden throttle changes, can lead to a rear wheel skid. The lateral forces acting on the tire can cause it to lose traction and slide out.
Insufficient Tire Grip: Worn-out or improperly inflated tires reduce their grip on the road, making them more prone to skidding. Additionally, using tires not suitable for the road conditions (e.g., using street tires on a loose or off-road surface) can lead to reduced traction and skidding.
Road Surface Conditions: Uneven or slippery road surfaces, gravel, oil spills, or debris can significantly reduce tire traction and cause a skid.
To avoid rear wheel skids, it's essential to practice proper braking techniques, modulating the throttle smoothly, and adjusting your riding style to the road conditions. Maintaining proper tire pressure, using appropriate tires for the terrain, and keeping them in good condition are also crucial for maximizing traction and minimizing the risk of skidding. Additionally, taking a motorcycle safety course can provide valuable knowledge and skills to help prevent skids and handle unexpected situations on the road.
