Fusion H2 Primary Clutch
The KWI Fusion H2 Primary Clutch is a fully billet, ground-up performance upgrade for the Kawasaki H2 CVT system — precision-machined from aerospace-grade materials and engineered to handle extreme horsepower, sustained heat, and aggressive riding conditions. Whether you're running a stock engine or a high-horsepower build, the Fusion H2 Primary delivers the strength, cooling, and adjustability the factory clutch was never designed to provide.
At the heart of the Fusion H2 Primary is KWI's Groovix Cooling Technology — an active airflow system that draws heat out of the clutch under load, reducing belt temperatures and extending belt life significantly compared to a standard primary. Combined with billet construction and a precision-tuned spring and weight system, the result is smoother engagement, stronger acceleration, improved throttle response, and more consistent power delivery through the entire RPM range.
Adjustable clutch tuning gives riders real control over performance — dial it in for terrain, tire size, elevation, or power level. This isn't a set-it-and-forget-it clutch. It's a platform you can tune as your build evolves.
This clutch wasn't just engineered behind a computer screen — it was built and proven in the desert with wheels on the ground. Broken Skull Racing and GFI Racing have been running the Fusion H2 Primary through some of the most demanding terrain imaginable. Real-world racing conditions where parts either survive or fail — and the Fusion H2 keeps delivering.
