Skis

http://www.snoped.com/trik-s-2.jpg

Skis are a very important part of a snowmachine because without them the rider can only go forwards, and backwards if the machine has reverse. With skis there are some important factors that give certain styles and edge over others. Skis need to be able to float in powder, take a tremendous beating on trails, and be light in weight to increase the overall economics of the machine. Skis are designed to have as little friction as possible in the forward direction but as much traction as possible side to side as to increase a riders ability to steer.
