Adherence Explanations

Track length selection of 154” X 16” X 3” (with short tunnel) means the machine is shorter than most deep snow tracks, this means easier maneuvering in technical terrain such as trees on a slope. However, reducing the track length reduces the track to surface area. To compensate for the loss of track surface area, increased horsepower (i.e. turbo) improves low end throttle response which compensates for the shorter track. This throttle responsiveness is throughout the throttle range and can be especially effective at elevations greater than 8,000 feet above sea level.

The adjustable limiter strap allows for increased control in the track suspension. When feathering the throttle during a difficult maneuver, this strap aids in increased power delivery to the ground and thereby avoiding unwanted wheelie situations and providing for a safer ride.

A 34-inch ski stance is a narrow ski width to assist in getting the machine on edge easier (which is necessary for any basic sled maneuver). Working in tandem with a narrow ski stance, full track rods will reduce dangerous wash out (back of the sled dropping downhill when contouring) and increase rider safety.

These features together allow for consistent machine operation on combinations of slopes up to and sometimes greater than 50%, tight cluster tree stands, and snow/powder more than 6 feet. Further, they aid in maintaining the high, smooth, and immediate power delivery necessary to perform technical maneuvers such as uphill blip/90 degree turns, sidehill (contouring) and up/down hill switch-backing.
