By selecting springs with different tension values, riders can customize the variator's behavior to suit their riding style or desired performance characteristics.

6. Integrated Variator Tuning Modules:

Integrated variator tuning modules, often referred to as ECU or TCU (Engine Control Unit or Transmission Control Unit) tuning modules, are aftermarket devices that allow users to modify the variator's behavior through electronic control. These modules plug into the vehicle's electronic system and enable adjustments to various parameters such as shift points, shift speed, and shift firmness. By modifying the variator's electronic control settings, users can enhance performance, improve throttle response, and customize the transmission behavior to match their preferences.

7. Variator Cooling Systems:

Aftermarket variator cooling systems are designed to improve the cooling efficiency of the variator. These systems often include additional cooling fins, heat sinks, or external coolers that help dissipate heat generated during operation. By improving cooling, aftermarket variator cooling systems can prevent overheating, reduce heat-related performance losses, and increase the overall durability of the variator. These upgrades are particularly beneficial for high-performance applications or when operating in extreme conditions.

In conclusion, aftermarket upgrades for variators offer a range of options to enhance their functionality and improve vehicle performance. Performance variator kits, adjustable variator pulleys, high-performance variator belts, upgraded sliders and roller weights, variator springs, integrated variator tuning modules, and variator cooling systems are some of the available upgrades.
