KEMIMOTO Heavy Duty Drive Belt for Polaris Sportsman, RZR, and Ranger

The most important aspect of maximizing the lifespan and performance of a new CVT belt is to break it in and cool it down correctly. Driving your ATV/UTV in two-wheel high for 20 minutes between 25-45 mph (40-72 km/h) on flat terrain, avoiding hard accelerations and hills, will result in a cooler-running belt. Shift the belt through the normal operational range by varying your UTV speed and engine RPM, but do not exceed ¾ throttle during break-in. In extremely cold weather, extend the break-in time by 5-10 minutes to allow the belt to warm up optimally. After 20 minutes of driving, let the unit cool down for 30 minutes after turning off the engine, then repeat the thermal cycle.

To further extend belt life, increase the speed limit washer to prevent the main clutch from closing too far at high speed, thereby preventing the secondary clutch from opening too far and the belt from falling onto the clutch shaft. Check whether the two clutches are aligned, and if not, use a clutch alignment tool to help straighten them. Keeping the clutch clean will also help improve performance and avoid clutch and belt wear. Adjust your driving style, and avoid violent accelerations on surfaces that are subject to a lot of slip (such as sand and dirt). Regularly check whether the vent of the CVT box is inserted.

The KEIMIMOTO ATV drive belts are designed with good rigidity, low elongation, small creep, and excellent heat resistance, performing well even in high-speed operation. The precise pitch design ensures a perfect fit, enhancing transmission efficiency and maximizing your UTV or ATV speed. The 450 belt is made with an aramid fiber cord that handles strong tension without breaking or stretching.

These drive belts are compatible with a wide range of Polaris Sportsman, RZR, and Ranger models, including the Sportsman Touring 570 EPS, Sportsman 450 H.O.
