Kimpex Commander WX4: a track system designed to push the limits of ATVs and UTVs

Off-road vehicles, such as ATVs and UTVs, are designed to tackle tough environments. However, certain conditions (deep snow, mud, wet ground, or unstable terrain) can quickly reduce the effectiveness of traditional tires. 

To address these challenges, the Kimpex Commander WX4 was developed, a track system that delivers increased traction, flotation, and versatility. Inspired by the Commander WS4, the WX4 features a more robust design and optimized performance, making it suitable for more powerful vehicles and demanding use. The goal was not simply to offer an accessory, but to truly expand the capabilities of ATVs and UTVs in extreme conditions.

The use of ATVs and UTVs has evolved significantly. They are no longer used solely for recreation; they have become essential in forestry, agriculture, maple syrup production, and many other professional sectors. In these environments, terrain conditions can deteriorate quickly, making mobility more challenging.

Track systems address these realities by allowing users to:

• Improve traction in snow or mud,
• Reduce pressure on soft ground,
• Limit vehicle sinking,
• Maintain mobility when tires reach their limits.

The WX4 is therefore part of a clear objective: to provide a high-performance solution tailored to the current needs of off-road vehicle users.

A system designed for multiple markets

Professional users

In many industries, ATVs and UTVs have become true daily work vehicles for maple syrup producers, forestry workers, farmers, as well as maintenance and response teams. For them, the ability to travel despite snow, mud, or thawing conditions is essential. Track systems, therefore, make it possible to extend vehicle use throughout the year. 

Recreational use

Off-road enthusiasts are also looking for solutions to access more technical environments: a remote cabin, snow-covered trails, muddy or unstable terrain. A track system helps maintain optimal mobility where tires are no longer enough.

Compatibility: from mid-size ATVs to full-size UTVs

For ATVs

The WX4 is designed for mid- to large-displacement ATVs, generally 500 cc and up. This category of vehicles offers an ideal balance between weight and power to fully benefit from a track system. Thanks to its design, the WX4 allows you to:

• Maximize traction in deep snow,
• Improve flotation on soft ground,
• Maintain mobility in critical environments.

For UTVs

The system is also compatible with several mid-size to full-size utility UTVs. It can support vehicles up to 2,700 lb, commonly used in agricultural and forestry sectors. On these machines, tracks provide:

• Improved mobility in snow or mud,
• Increased stability when carrying equipment,
• Enhanced traction on uneven terrain.

A development supported by multiple areas of expertise

The development of a track system like the WX4 relies on various specialized expertise within the Soucy enterprises.

Design and engineering

The Soucy Powersports team handled the system’s design, performance optimization, and integration across multiple ATV and UTV platforms.

Key system components

• Tracks: produced by Soucy Rubber Tracks, recognized for its expertise in solutions for off-road vehicles. 
• Rubber compounds: developed by Soucy Techno to ensure durability, resistance, and flexibility.
• Sprockets and wheels: manufactured by Soucy Plastiques, experts in high-performance polymers.   

   

Assembly and distribution

The system is assembled by Soucy Track Systems, a unit dedicated to track solutions. Finally, Kimpex handles marketing and distribution, making the WX4 accessible through a wide network of dealers and users.

System performance

• Increased contact surface (+19%)

The WX4 offers a larger contact surface, improving flotation in snow and soft ground. This reduces sinking and ensures more stable forward movement.

• Aggressive track profile

The aggressive tread pattern maximizes traction, whether in deep snow, mud, or highly uneven terrain.

• Improved weight-to-flotation ratio

Each track can support up to 403 lb (183 kg), ensuring solid load capacity while maintaining excellent mobility on soft ground.

• New 19-tooth sprocket option

This configuration provides an approximate 8% increase in speed while maintaining optimal traction. It offers greater flexibility depending on the application.

• Optimized guidance system

The slide-free system reduces energy loss and limits wear, delivering consistent performance in demanding conditions.

A new approach to off-road mobility

Track systems like the WX4 illustrate the evolution of off-road riding. Rather than limiting the use of an ATV or UTV to certain seasons, they allow the vehicle to adapt to the conditions encountered. With the WX4, off-road mobility no longer depends on conditions;  it adapts to them. To learn more about the WX4 and explore its features, check out :

Understanding key features

• Load capacity: maximum supported weight (vehicle + rider + equipment)
• Flotation surface: area in contact with the ground
• Ground pressure: ratio between weight and surface area
• Ground clearance: generally increased with tracks
• Speed reduction: linked to sprocket diameter and system configuration
