雪地摩托具有履带和雪橇的组合，就大大增加了车辆接触地面的面积，从而减小了雪地摩托对地面的压强，这样沉重的车辆就不会深陷在松软的雪中而无法前进了。
With the combination of track and sled, snowmobiles greatly increase the area of vehicle contact with the ground, thus reducing the pressure of snowmobiles on the ground, so that heavy vehicles will not sink in the soft snow and cannot move forward.
雪地摩托的履带也不同于一般的履带，而是采用橡胶制成，这样能够有效减轻自身的重量，雪地摩托便可以在冰雪之中更加灵活地前行。
The tracks of snowmobiles are also different from those of ordinary ones. They are made of rubber, which can effectively reduce their own weight. Snowmobiles can move more flexibly in the snow and ice.
同时，在履带表面也分布着不少钢钉，这些钢钉能够在行驶过程中插入光滑的地面之中，这样雪地摩托就不用担心打滑失控。
At the same time, there are many steel nails distributed on the surface of the track. These steel nails can be inserted into the smooth ground during the driving process, so that the snowmobiles do not have to worry about slipping out of control.
为了能在比赛中一骑绝尘，一马当先，竞速型雪地摩托必须具有过人的动力性能，经过改良的雪地摩托，配备了动力强劲的发动机，同时使用铝合金等新型材料制作的轻量化车身，也为这个大块头做了一次彻底的瘦身改造。
In order to get ahead of the competition, the racing snowmobiles must have excellent power performance. The improved snowmobiles are equipped with powerful engines. At the same time, the lightweight body made of new materials such as aluminum alloy has also made a thorough slimming transformation for this large head.
