Skandic is a large family of Ski-Doo utilitarian snowmobiles. There are models with 2- and 4-stroke engines, with wide and very wide tracks, arched and telescopic suspensions * And all of them are “workhorses”. But in any case, they are beautiful, richly equipped and fast.

The 600 cmz Rotax engine delivers 90 liters. with. However, for the “working” snowmobile, the main advantage is not power, but the developed traction force - it provides it with all-terrain cross-country ability and the ability to transport heavy loads. In low gear, you can easily take out a huge moose from the thicket or pull out an unlucky jeep in tow from a snow quagmire. After all, the wider and longer the caterpillar, the higher the snowmobile's ability to move forward, and not down, into the snow mass.

The creative genius of Canadian engineers is fully embodied in the chassis, and it deserves a detailed description. To begin with - about the arched levers of the front suspension with an impressive 185 mm stroke. Such longitudinal levers, unlike traditional straight lines, add geometric cross-country ability to the snowmobile, and more simply, they do not cling to bumps and treacherous stumps hidden under fluffy snow. And about their other dignity. The technique breaks down - there is no escape from this. But replacing a bent lever and overhauling the suspension and frame are two different troubles. On a Skandic WT SUV in the event of a strong blow (say, when at a speed of "about a hundred" the ski hits a large rock), the arched lever will take the energy of the impact on itself. The ordinary, in such cases, courageously resists. And in vain, since "courage" spills into a deformed frame and broken pendants.

Now about the frame. It is steel, which means it is strong and durable. Alloy frames are also installed on snowmobiles, however, given their elasticity, they are not suitable for a “snow tank”. And from scratches and chemical influences of the environment, the Skandic steel frame is reliably protected by a special high-resistant coating.

It is especially fun to ride a snowmobile through the forest. The Skandic WT SUV has a small turning radius, and this is due to the kinematics of the new front suspension and the presence of reverse gear. And one more interesting "trick": the rear floating carriage is installed at a slight angle. Thanks to this, the snowmobile easily backs away without burying itself in loose snow. In the confined space of a dense forest, this advantage can be vital.

The rear suspension is adapted to overcome obstacles to ride on difficult terrain. The caterpillar, as we recall, is long, so the suspension travel of 293 mm when moving through the hill will not allow you to lose traction.
