About this product

The KWI Speed Fusion Belt was custom-engineered specifically for the KWI Fusion Speed UTV Clutch System — precision-built to exact KWI specifications and tested over tens of thousands of real-world miles before it ever reached a customer. This isn't an off-the-shelf belt adapted to fit. It was developed in tandem with the Fusion System itself, designed from day one to work as an integrated component of the complete clutch package.

The result is a belt that delivers unmatched strength, grip, and reliability under the extreme loads and temperatures generated by high-performance Speed UTV riding. Every dimension, compound, and tolerance was dialed in alongside the primary and secondary clutch — because a system is only as strong as the belt running through it.

Confirmed fitment: Compatible with all 2026 Speed UTV models running KWI-designed clutches, all KWI-designed retrofits, and updated Speed UTV clutch revisions. KWI engineered both the clutch system and the belt — they're built to work together.

Why it matters

We built the clutch. We built the belt. They were designed for each other.

Most belts are engineered to fit a range of applications. The Speed Fusion Belt was engineered for one: the KWI Fusion System. That means every dimension and compound is optimized for the exact loads, temperatures, and shift characteristics of this clutch — giving you a drivetrain that performs as one complete, validated system.
