A lean angle in the context of motorcycles refers to the angle at which a motorcycle is leaning while taking a corner or making a turn. It is the degree of tilt the motorcycle achieves while maintaining balance and traction during a turn.
When a motorcycle leans into a corner, the tires need to maintain sufficient grip on the road surface to ensure stability and control. The lean angle is determined by the speed of the motorcycle, the radius of the turn, and the rider's input.
Motorcycles with a higher lean angle capability are typically sport bikes or racing motorcycles designed for aggressive cornering. These bikes have a combination of factors that allow them to achieve greater lean angles, such as a lower center of gravity, stiffer suspension, and specialized tires with increased traction.
Riders who are skilled in cornering can effectively manage and control the lean angle of their motorcycle, allowing them to navigate turns smoothly and safely. However, it's important to note that excessive lean angles can lead to loss of traction and result in a loss of control or a low-side crash. Therefore, it's crucial for riders to understand their motorcycle's capabilities and ride within safe limits.
