More air. Lower temps. Simpler install.
This Oversize Cooling Fan for Yamaha JOG 50 increases airflow through the CVT cover to help steady belt and sheave temperatures in stop-and-go riding. The 100 mm diameter boosts throughput, and the spacerless hub sets stack height correctly for clean, wobble-free running—no washer/spacer needed.
