EPI Sport Utility Clutch Kit for 2018–2024 Yamaha Wolverine 850 X2/X4 (27–28 Inch Tires)
Upgrade your Yamaha Wolverine 850 X2 or X4 with the EPI Performance Sport Utility Clutch Kit WE437617, engineered for models running 27–28 inch tires at elevations between 0–3000 feet. This all-purpose clutch kit is designed to restore lost power caused by oversized tires while improving overall performance, responsiveness, and efficiency.
Larger tires can significantly reduce acceleration and throttle response due to increased weight and rolling resistance. This EPI clutch kit recalibrates your CVT system to compensate for these changes, delivering stronger low-end torque, smoother midrange performance, and consistent power delivery across a wide range of riding conditions.
