Using the latest analytical tools WST designs suspension systems to meet our customers' specific platform requirements.  WST is committed to sustainable operations in all manner of product design, development and end–use.  Ours is a systems approach and therefore not intended for kit form.



Product Description / Characteristics

The product is the world's first and only long travel leaning suspension system.  A WST equipped vehicle provides long-travel suspension capability through all designed lean angles.  Fluid operator control results from match-critical machining of high-performance materials.  The WST system is an active (smart) system.  Components in the steering column measure an operator's natural steering inputs and mass-shift.  These measurements are transmitted to an ECU (Electronic Control Unit) which then affects control of a small hydraulic drive system to lean-assist the vehicle thereby substantially improving stability and control.  The system is intrinsically safe.  Electromechanical lean-assist, even at failure, cannot override operator control, which is insured via system geometry.

For the first time, a vehicle will have all the benefits of an off-road style long travel suspension while maintaining the control needed for road racing.

Why lean a vehicle?

During a cornering sequence the forces acting to roll a vehicle out of a corner are balanced by the vehicles ability to shift/lower its center of gravity.  This ability provides the most effective and efficient method to safely navigate through a cornering sequence.

Any vehicle design conducive to leaning suspension technology will realize significant improvements in stability and performance utilizing the WST system.  Our core design focus is operator control and safety.

The Wesll Ski-Machine employs proprietary leaning technology and custom skis–with edges, not standard snowmobile skids with carbides.  Skis are engineered to deflect and carve, skids are not.  Directional stability is imparted to our machine through ski camber and toe adjustment which provides approximately 8 feet of total effective edge.  Conversely, the present day modern snowmobile is directed by approximately 6-24 inches of total carbide, usually located in the center of their short skids.

Ideally a snowmobile needs to maximize the surface area it presents to the snow in order to provide optimal traction and flotation to prevent it from getting stuck.

Problem: Increasing track size makes a machine more difficult to control on the trail.
Solution: Stop snowmobiling, start skiing.

Leaning is the solution, not only is it safer, it's much more fun.  Skiing provides the ability to quickly change direction whilst maintaining control and stability.  Operating a machine that leans outboard while cornering seems kind of…not so smart.

It is now possible to ski your snowmobile…the additional capabilities provided by the Wesll active suspension system improves the operators' critical decision/response time.  The result is increased control and safety with a considerable reduction in operator fatigue.

Our Ski–Machine uses custom skis, with 8 feet effective edge, coupled to an intelligent leaning suspension providing quality feedback and high sensitivity to operator input.  Our rounded long track is optimized for flotation and hook–up.  The result is a hybrid system providing increased flotation in deep snow with superior directional stability and control on trail.  The WST Ski–Machine is a welcome paradigm shift in terms of performance, control and safety…

The studded aspect of the tracks lateral radius' improves roll–rate and hook–up exactly where and when needed–turning/cornering.  Steering and leaning the snowmobile into a corner quickly rolls the track onto its studded edge.  The result is a (stable) optimized system able to handle much greater loading along the entire length of its long track and skis.
