There are several common reasons why a motorcycle may fall over while cornering or turning at low speeds. These can include:
Lack of balance and control: Maintaining balance and control while cornering or turning at low speeds requires proper body positioning, weight distribution, and throttle control. Inexperienced riders or those who haven't developed these skills yet may struggle to maintain stability, leading to a fall.
Improper technique: Incorrect cornering or turning techniques can contribute to a motorcycle falling over. This can include improper countersteering (pushing on the handlebars in the opposite direction to initiate a turn), using excessive or abrupt throttle inputs, or not looking through the turn and instead fixating on an obstacle or the ground.
Insufficient lean angle: When leaning into a turn, motorcycles rely on the traction between the tires and the road to maintain stability. Insufficient lean angle can result in the tires losing traction and causing a fall. This can happen if the rider is too upright or leans the bike too little for the given speed and radius of the turn.
Overuse of front brake: Overuse or excessive application of the front brake while turning at low speeds can cause the front tire to lose traction, leading to a fall. It's important to use a gentle and progressive application of the brakes while maintaining proper weight distribution.
Sudden or excessive throttle inputs: Rapid or aggressive throttle inputs, especially when combined with improper body positioning, can lead to a loss of traction and loss of control. Smooth and controlled throttle modulation is essential while cornering or turning at low speeds.
Obstacles or surface conditions: Uneven surfaces, gravel, oil spills, or other obstacles on the road can compromise tire grip and stability, causing the motorcycle to fall over. It's important to scan the road ahead and adjust speed and line selection accordingly.
Insufficient tire traction: Worn-out or improperly inflated tires can reduce traction, particularly in low-speed maneuvers. Inadequate traction can make it more difficult to maintain stability while cornering or turning, increasing the risk of a fall.
To mitigate the risk of falling over while cornering or turning at low speeds, it's important to practice and develop good riding techniques, such as proper body positioning, smooth throttle control, and maintaining an appropriate lean angle. Additionally, regular maintenance and checks of tire condition and pressure can help ensure optimal grip and traction.
