Because of the angle of the spindle on the snowmobile, the ski tips as it turns. This action puts more downforce (pressure) directly on the "inside" runner. This creates better "bite" when cornering. The ski is also self-centering when in forward motion. This means that it tracks true. This is accomplished through the basic design of the ski. It is similar to an upright triangle. The top point being the spindle and the bottom two points being the runners. As pressure or down force is put on the top of the triangle, the natural tendency is for the bottom corners to level out or take equal pressure thus creating the very stable feeling unique to the dual keel design. This also allows the Flexi-Ski to track true and not follow the ruts left by other skis. |
