In the context of motorcycles, the term "rake" refers to the angle between the steering axis (the line passing through the steering head and the center of the front wheel) and a vertical line. It is also known as the "fork angle" or "steering head angle."
The rake angle plays a crucial role in determining the handling characteristics of a motorcycle. A greater rake angle, which means the steering axis is tilted farther back, generally results in a longer wheelbase and more stability at higher speeds. Motorcycles with a greater rake angle tend to have a straighter-line stability and are often used for touring or cruising purposes.
Conversely, a smaller rake angle, where the steering axis is more upright, leads to a shorter wheelbase and quicker steering response. Motorcycles with a smaller rake angle are typically more agile and maneuverable, making them suitable for sports-oriented riding or city commuting.
The rake angle is just one factor that influences a motorcycle's handling characteristics. Other factors include the trail (the distance between the contact point of the front tire and the imaginary line extending through the steering axis), the weight distribution, and suspension settings. All these elements work together to create the overall handling characteristics of a motorcycle.
