Introduction
When it comes to upgrading motorcycle performance, even small changes can have a big impact. One change that riders can consider is switching to lightweight swing arms. Traditionally, swing arms have been made of steel, but in recent years, manufacturers have begun experimenting with lighter materials like aluminum.
Benefits of Lightweight Swing Arms
There are several benefits to using lightweight swing arms on motorcycles. One of the main advantages is an increase in speed. By reducing the weight of the motorcycle’s swing arm, riders may find that their bike accelerates faster and reaches higher speeds more easily.
Another benefit of lightweight swing arms is improved handling. When the weight of the swing arm is reduced, the motorcycle becomes more agile and responsive. Riders may notice that their bike is easier to maneuver and requires less effort to steer through corners and curves.
Finally, lightweight swing arms can also reduce the strain on the motorcycle’s suspension system. When the suspension is not weighed down by a heavy swing arm, it can work more efficiently to absorb bumps and shocks on the road.
Materials Used for Lightweight Swing Arms
There are several materials that are commonly used to make lightweight swing arms:
Aluminum
Aluminum is a popular choice for lightweight swing arms because it is strong and lightweight. It is also corrosion-resistant, which makes it ideal for use on motorcycles that are ridden in wet or humid environments. Additionally, aluminum can be machined into complex shapes, which allows manufacturers to create swing arms with unique designs that are both functional and aesthetically pleasing.
Titanium
Titanium is even lighter than aluminum, which means that it can further reduce the weight of the motorcycle’s swing arm. However, titanium swing arms are more expensive than aluminum swing arms and may not be as widely available. Additionally, titanium is more difficult to machine than aluminum, which can make it harder to create complex designs.
Carbon Fiber
Carbon fiber is a high-tech material that is both strong and lightweight. It is commonly used in the aerospace and automotive industries for its excellent strength-to-weight ratio. Carbon fiber swing arms can be very light, but they are also expensive. Additionally, carbon fiber is more brittle than metals like aluminum and titanium, which means that it may not hold up as well in crashes or impacts.
Considerations When Choosing a Lightweight Swing Arm
When choosing a lightweight swing arm, riders should consider several factors:
- Cost: Lightweight swing arms can be expensive, especially if they are made of titanium or carbon fiber. Riders should consider their budget when deciding which material to choose.
- Functionality: Riders should consider the type of riding they will be doing and choose a swing arm that is appropriate for their needs. For example, a swing arm designed for track racing may not be the best choice for long-distance touring.
- Aesthetics: While not as important as functionality or cost, the appearance of the swing arm can be a consideration for some riders. Aluminum swing arms can be machined into complex designs and may offer more visual appeal than more utilitarian swing arms made of titanium or carbon fiber.
Conclusion
Lightweight swing arms can be a worthwhile investment for riders who want to improve the performance and handling of their motorcycle. By reducing the weight of the swing arm, riders may find that their bike accelerates faster, handles better, and offers a smoother ride. Additionally, lightweight swing arms can be made of a variety of materials, each with their own advantages and disadvantages. When choosing a swing arm, riders should consider factors like cost, functionality, and aesthetics to find the best option for their needs.
