KWI Clutching - Polaris RZR Pro R / RZR 4 Pro R Fusion Pro R Clutch System

KWI Fusion Pro R Clutch System is a complete, next-generation CVT solution for the Polaris RZR Pro R. It combines the Fusion Pro R Primary and Fusion XR Floating Secondary into one fully optimized package engineered to work together as a single high-performance system.

Built from aerospace-grade billet construction with advanced airflow design, this system eliminates common factory CVT weaknesses: belt heat, inconsistent RPM control, poor backshifting, and power loss through the drivetrain.

Fusion Pro R Primary delivers improved power transfer, stronger acceleration, and full adjustability. Tune for your exact horsepower level, tire size, terrain, and riding style.

Fusion XR Floating Secondary introduces a true floating design that allows the clutch to self-align under load for the cleanest, most efficient belt-to-sheave contact. Benefits include reduced side-load, lower belt temperatures, improved backshifting response, and more consistent power delivery across all terrain and riding conditions.

The Fusion XR Secondary enables fine-tuning of final drive ratio through belt selection. Run different belt sizes to adjust gearing for dunes, high-speed desert, rocks, or mud without modifying the gearbox.

Available Configurations:

• Primary Only — Upgrade engagement, power transfer, and tuning control
• Secondary Only — Reduce belt heat, improve alignment, and extend belt life with floating design
• Full Fusion System — Primary and Secondary together for maximum performance, cooling, and efficiency

Compatible with: 2022+ Polaris RZR Pro R and 2022+ Polaris RZR Pro R 4
