A looped middle link, also known as a "single-sided swingarm" or "banana swingarm," is a design feature found on some motorcycles where the swingarm on one side of the rear wheel is connected to the frame using a single, curved member. This design has several effects on the motorcycle:
Aesthetic appeal: One of the primary effects of a looped middle link is its visual impact. It gives the motorcycle a unique and distinct appearance, often considered more stylish and futuristic. This design feature is commonly seen in high-end sport bikes and exotic motorcycles.
Accessibility: The looped middle link design can make certain maintenance tasks, such as rear wheel removal, easier compared to a traditional dual-sided swingarm. The single-sided swingarm allows for simpler access to the rear wheel, chain, and sprockets, simplifying maintenance and reducing the time required for certain tasks.
Weight savings: In some cases, a looped middle link design can provide weight savings compared to a dual-sided swingarm. By using a single-sided swingarm, manufacturers can reduce the overall weight of the motorcycle, which can contribute to improved performance, handling, and maneuverability.
Showcasing the rear wheel: With a looped middle link, the rear wheel becomes more prominently displayed. This design can enhance the aesthetic appeal by showcasing the wheel design, brake components, and other rear-end features.
Stiffness and stability: The looped middle link design can offer improved stiffness and stability to the rear suspension system. By connecting the swingarm to the frame at a single point, the design can provide enhanced rigidity, contributing to better handling and control during cornering and high-speed maneuvers.
It's important to note that the specific effects and benefits of a looped middle link design can vary depending on the motorcycle model and engineering considerations. Different motorcycles may have unique variations and characteristics associated with their specific single-sided swingarm design.
