The Kimpex Rouski system is a caster wheel attachment designed for snowmobiles, intended to facilitate travel on roads and surfaces other than snow. Installation involves modifying the ski assembly, and the system is adaptable to various snowmobile models through the use of specific mounting plates. The system’s utility is particularly noted for navigating transitions between snow-covered trails and paved surfaces, reducing wear on skis during such travel. While offering convenience, the Rouski system may impact snowmobile handling in deep snow conditions due to added weight and reduced floatation.
System Overview and Adaptability
The Kimpex Rouski system is designed with a universal base, with modifications occurring in the mounting plate to accommodate different snowmobile runner types. This allows for a single Rouski model to be compatible with a wide range of snowmobiles. The system’s primary function is to provide a wheeled interface for the skis, enabling smoother and more controlled movement on surfaces where skis would typically struggle, such as asphalt or gravel roads.
Installation Procedure
Installation of the Kimpex Rouski system requires lifting the front of the snowmobile to access the skis. The process involves removing the main ski bolt and replacing it with a bolt and adapter that secures the Rouski system. It is crucial to identify the left and right sides during installation, as the activation pedal is positioned at the front of the assembly and the wheel is oriented towards the center of the snowmobile.
The installation procedure includes the following steps:
- Remove the existing ski bolt.
- Insert the Rouski system adapter, ensuring correct left/right orientation.
- Replace the original bushing on one side with a washer provided in the installation kit.
- Secure the adapter plate firmly to the ski using the main bolt.
- Tighten the bolt to the manufacturer’s recommended torque specification.
- Drill a quarter-inch hole through the ski to secure the adapter plate. The documentation specifies that drilling occurs through the plastic of the ski.
- Insert a bolt into the newly drilled hole to further secure the assembly.
- Finally, install the caster wheel onto the adapter plate.
These steps are repeated for the second ski to complete the installation.
Drilling and Hardware Specifications
The installation process requires drilling a hole in the ski using a quarter-inch drill bit. Kimpex offers a specialized drilling tool (Product No. 373920) for this purpose. If this tool is unavailable, a standard drill bit of ½ inch can be used, requiring temporary removal and reinstallation of the skid plates.
The system utilizes M8-1.25 self-locking flange nuts for securing components. An exploded view diagram is available in the documentation to illustrate the assembly and hardware arrangement.
Considerations for Use
According to user feedback, the Kimpex Rouski system is particularly beneficial for snowmobilers who frequently encounter roads or paved surfaces during their rides. This is especially relevant when accessing trails or navigating areas where gas stations are cleared of snow, as sliding on asphalt can compromise control. The system helps to mitigate ski wear on abrasive surfaces.
However, the documentation and user experience indicate potential drawbacks in off-trail or deep snow conditions. The added weight of the system can reduce the snowmobile’s floatation, and the wheels may obstruct movement in deep powder. The system is therefore not recommended for use in mountainous terrain or off-trail environments.
Advantages and Disadvantages
Based on user experience, the Kimpex Rouski system presents the following advantages:
- Quick and easy installation.
- Clear and precise instructions.
- High product quality and reliability.
Conversely, the system has the following disadvantages:
- Adds weight to the skis.
- Reduces floatation in deep snow.

Conclusion
The Kimpex Rouski system offers a practical solution for snowmobilers who frequently transition between snow-covered trails and paved surfaces. Its relatively straightforward installation and adaptability to various snowmobile models make it a convenient option for those seeking to reduce ski wear and improve control on roads. However, users should be aware of the potential drawbacks in deep snow conditions, where the added weight and reduced floatation may negatively impact performance. Careful consideration of riding conditions and intended use is essential when determining the suitability of the Kimpex Rouski system.
