Lowering a motorcycle can have a significant impact on its handling characteristics. Lowering refers to modifying the suspension system to reduce the ride height of the motorcycle, typically by lowering the front forks and/or adjusting the rear suspension.
Here are some effects of lowering a motorcycle on its handling:
Reduced ground clearance: Lowering a motorcycle decreases the distance between the bottom of the bike and the ground. This can result in reduced ground clearance, making the motorcycle more prone to scraping or bottoming out when navigating over bumps, speed bumps, or during aggressive cornering.
Altered steering geometry: Lowering the front forks affects the steering geometry of the motorcycle. It reduces the rake angle (the angle between the steering axis and the vertical axis) and decreases trail (the distance between the contact patch of the front tire and the point where the steering axis intersects the ground). These changes can make the motorcycle's steering feel quicker and more responsive, but it may also result in reduced stability and increased sensitivity to input.
Altered suspension dynamics: Lowering the rear suspension can affect the motorcycle's suspension dynamics. It reduces the rear suspension travel and may lead to a harsher ride quality. The reduced suspension travel can also limit the ability of the suspension to absorb bumps and maintain traction, potentially affecting overall comfort and control.
Changes in center of gravity: Lowering a motorcycle lowers its center of gravity, which can provide a more planted and stable feel, especially during low-speed maneuvers and at a standstill. This can be beneficial for riders with shorter inseams, as it may improve their confidence and ability to handle the bike while stopped or at slow speeds.
Increased seat height discomfort: While lowering a motorcycle can make it more accessible for riders with shorter legs, it can also affect taller riders by reducing seat-to-footpeg distance. This change may result in a more cramped riding position, leading to discomfort during longer rides.
It's important to note that lowering a motorcycle should be done carefully and preferably with the guidance of a professional or experienced mechanic. Any modification to a motorcycle's suspension should be considered in the context of the rider's specific needs, preferences, and the intended use of the motorcycle. Additionally, other factors such as tire clearance, suspension travel, and overall balance should be taken into account to ensure that the motorcycle's handling remains safe and predictable.
