当摩托车不仅作为生活用品,也作为一种体育用品而受到注目时,可以看到其进化的一个方向是大排量化。既要快速,又要给后轮加力而灵活地操纵摩托车,就必须提高发动机的输出功率。因此,发动机排量增加是不可避免的。 当发动机的排量超过100mL时,其最高速度超过20km/h已是轻而易举的事了。现在要考虑是否能超过300km/h了。但是在性能提
When a motorcycle is not only used as a daily necessities but also as a sporting goods, it can be seen that one direction of its evolution is its large displacement. It is necessary to quickly, but also to force the rear wheel and flexible control of motorcycles, you must increase the engine’s output power. Therefore, the increase of engine displacement is inevitable. When the engine displacement of more than 100mL, the maximum speed of more than 20km / h has been a breeze. Now consider whether it can exceed 300km / h. But in terms of performance
