Question

What causes the back tire of my motorcycle to feel like it's sliding out when I brake suddenly in an emergency situation? Is this dangerous?

Answer 1

When the back tire of a motorcycle feels like it's sliding out when you brake suddenly in an emergency situation, it is usually due to a phenomenon called rear-wheel skid or rear-wheel lockup. This occurs when the braking force applied to the rear wheel exceeds the available traction between the tire and the road surface.

There are a few factors that can contribute to this situation:

1. Weight transfer: During hard braking, weight transfers from the rear to the front of the motorcycle, reducing the weight and traction on the rear wheel. This imbalance can cause the rear tire to lose traction and slide.

2. Braking technique: Applying excessive force to the rear brake, especially in a panic situation, can easily overpower the available traction and result in a rear-wheel skid. Proper modulation of the brakes, with a focus on using the front brake more effectively, can help prevent this.

3. Road conditions: The condition of the road surface can also play a significant role. Slippery or uneven surfaces, gravel, oil spills, wet roads, or other hazards can decrease tire grip and increase the likelihood of a skid.

4. Tire condition: Worn-out or improperly inflated tires have reduced grip and are more prone to skidding. It's essential to maintain proper tire pressure and ensure sufficient tire tread depth for optimal traction.

5. Motorcycle design: Certain motorcycle designs, such as cruisers or bikes with a long wheelbase, can be more susceptible to rear-wheel skids due to weight distribution and suspension setup.

Yes, a rear-wheel skid is dangerous as it significantly reduces your ability to control the motorcycle. It can lead to loss of stability and potential loss of control, which may result in a crash or loss of balance. To minimize the risk of a rear-wheel skid, it is crucial to practice proper braking techniques, stay alert and anticipate emergency situations, and maintain your motorcycle in good condition. Additionally, taking advanced rider training courses can improve your skills and help you handle emergency situations more effectively.
