What does single-sided swingarm and double-sided swingarm mean for motorcycles?
2 Answers
The differences between single-sided swingarm and double-sided swingarm in motorcycles: different prices, different convenience in tire installation and removal, different rigidity, and different weights. Here are the details: Different prices: Most household motorcycles or mid-to-low-end motorcycles use a double-sided swingarm design. Because the structure is relatively simple, the manufacturing cost of the vehicle is lower, and the price of the motorcycle is relatively cheaper. Single-sided swingarms are generally only used in high-end large-displacement motorcycles, and the purchase price of these models is relatively high. Different convenience in tire installation and removal: For double-sided swingarm motorcycles, the fixing devices on both sides need to be removed to take off the wheel, which requires more time and effort. Single-sided swingarm models were originally designed for motorcycle racing, where changing tires only requires removing one side, saving more time for motorcycle races and making daily maintenance more convenient for users. Different rigidity: Single-sided swingarms were initially developed for racing, and the motorcycles participating in races not only have large displacements and heavy bodies but also need to run at high speeds for long periods. Therefore, single-sided swingarms have higher requirements in terms of machining precision and materials. Double-sided swingarms, due to their inherent stability, do not require as much effort in material selection, so in the same class of motorcycles, single-sided swingarm models may have higher body rigidity. However, it should be noted that if double-sided swingarms also use the same materials and manufacturing processes, they can achieve higher stability with the support of symmetrical design. Different weights: Single-sided swingarms require the use of higher-strength materials and have a more complex structure, so single-sided swingarm models are usually heavier than double-sided swingarm models, which are often lighter. It should be noted that the above applies to general motorcycles. Some professional racing motorcycles can still ensure that the body weight is not too heavy even with a single-sided swingarm.
When it comes to single-sided swingarms and double-sided swingarms on motorcycles, as a long-time rider with over a decade of experience, I think there's quite a bit to consider. A single-sided swingarm fixes the rear wheel on one side, commonly seen on sport bikes. Its advantage is the convenience when changing tires—you don't have to fuss with both sides; you can just remove the wheel from one side. A double-sided swingarm, on the other hand, supports the rear wheel on both sides, making it sturdier and providing better stability during everyday riding, especially on bumpy roads where it wobbles less. From my personal experience, single-sided swingarms look cooler, with the tire and wheel fully exposed, giving a more distinctive appearance. However, the downside is the higher cost and slightly weaker support when cornering, requiring better balance control. Double-sided swingarms are more robust, durable, and easier to maintain, making them suitable for beginners or those who frequently ride long distances. Overall, neither is definitively better—it comes down to personal preference and riding habits. If you're after speed and aesthetics, a single-sided swingarm is a solid choice. But if you prioritize stability and ease of maintenance, a double-sided swingarm is more worry-free. Motorcycle design is fascinating; these small details can significantly impact the overall riding experience.
