First of all, the main composition of the motorcycle structure no matter what model, mainly divided into appearance, engine, frame, suspension, electronic control several aspects. The main problem is mainly focused on the scooter frame and suspension structure and connection.

As we all know, most of the common scooter engine will act as a part of the frame structure, take the structure of the straddle class model, the scooter engine acts as the rear rocker arm, that is, the small partners said after the flat fork.

This makes the scooter's structure somewhat similar to the straddle type of single rocker arm, which is determined by its frame structure and engine transmission form, and will not easily change, unless there is a breakthrough in transmission form, if the CVT gearbox and belt drive are still used, this "single rocker arm" shape will always exist.

However, please note that the "single rocker arm" of the scooter is completely unable to be compared with the straddle bike in terms of functionality, it only uses a unilateral connection from the structure and feel, and does not have the characteristics of improving control, enhancing the appearance, and convenient disassembly.

Of course, another meaning under the current issue may also focus on the setting of the rear suspension, that is, why the scooter uses a single shock absorber to connect the frame and the rear rocker arm. In other words, why do some scooters use single-side shock absorbers instead of double-side shock absorbers?

This phenomenon is more common in small displacement scooters, especially models of about 10,000 yuan, and they are very keen on the application of single shock absorbers.

This topic is a bit of a cliche, of which some riders agree with the statement is that "manufacturers are cutting corners, can save a root to save a root." Although this argument is debatable, it is also able to withstand scrutiny, after all, it is no secret that factories are squeezing costs.

However, please note that one or two factories can still make sense of this operation, but it seems that there are not many scooters with rear unilateral shock absorbers, which is worth our deep digging.

According to my observation, at the same price, niche brand models prefer to use double-side rear shock absorption, theoretically speaking, this type of model should reduce the cost and reduce the price, but why does it need to install more shock absorbers?

The reason here is that the soft connection effect of the shock absorber does not only depend on its number, but also depends on its own filtration capacity and preload level, in other words, two ordinary post-shock absorbers, in the use of the effect is certainly not as good as a high-quality shock absorber.

If the actual effect of one shock absorber can meet the needs of the current vehicle, then there is no need to install two bad shock absorbers to act as the king of numbers.

Therefore, although the single shock absorber design of the 10,000 level scooter has the possibility of simple configuration, the models of the mainstream brands are more about the trust of the supporting products and the affirmation of the vehicle adjustment.

In summary, the core of the problem described in the title is that the "single rocker arm" design of the scooter belongs to the vehicle-specific standard and cannot be easily changed. As for the application of single shock absorber mainly depends on the cost and shock absorption effect.
