Harley-Davidson motorcycles, like most motorcycles, lean when turning corners as a fundamental principle of physics known as countersteering. Countersteering is the technique riders use to initiate a lean by momentarily steering in the opposite direction of the desired turn.
Here's how the process works:
Initiation: As the rider approaches a corner and wants to turn, they apply a slight amount of pressure to the handlebar on the side opposite the direction of the turn. For example, if turning right, a gentle push on the left handlebar is applied. This momentary input causes the front wheel to briefly turn slightly in the opposite direction, causing the motorcycle to lean.
Lean: When the front wheel is turned opposite to the desired turn direction, the motorcycle's inertia and the forces acting on it cause it to lean into the corner. The centrifugal force generated as the motorcycle leans helps balance the gravitational force acting on it, allowing it to maintain stability while cornering.
Balance and Steering: Once the motorcycle is leaned into the turn, the rider maintains balance and controls the path by making small steering adjustments. These adjustments are typically made by applying pressure to the handlebar on the side of the turn. For example, to steer right, the rider applies gentle pressure to the right handlebar.
Exiting the Turn: As the rider completes the turn, they gradually reduce the pressure on the handlebar and allow the motorcycle to straighten up. The motorcycle returns to an upright position as the forces acting on it become balanced again.
It's important to note that leaning into turns requires skill and practice, and riders should always follow safe riding techniques and exercise caution when maneuvering corners. It's recommended to take a motorcycle safety course or consult experienced riders for guidance on mastering cornering techniques.
