• Compatibility: Direct replacement set of eight variator rollers engineered to match the weight (likely 18-25 grams as indicated by "25G"), dimensions (30mm), and grade for consistent shift performance in the specified models.
• Weight: The weight range (e.g., 18-25g) influences the clutch's engagement RPM and shift curve. The specific "25G" likely indicates a 25-gram roller, which would engage at a higher RPM than a lighter one, affecting acceleration characteristics.
• Construction: Manufactured from a durable, heat-resistant polymer or nylon composite that maintains its shape and provides a smooth rolling under centrifugal force and clutch .
• Function: These rollers ride on ramps inside the primary clutch. As engine RPM increases, centrifugal force pushes them outward, causing the movable sheave to close and change the drive ratio.
• Application: A consumable wear item and tuning component within the CVT; replacing worn rollers restores shift points, and changing weight can fine-tune acceleration for specific riding styles or conditions.
