JOG 90 Generator Cooling Fan

Fresh air through the shroud. Lower temps. Bolt-on color.

This Alternator Cooling Fan for Yamaha JOG 90 drives fresh air across the cylinder shroud to help stabilize head and barrel temperatures during city stop-and-go riding. The lightweight 38.5 g design minimizes rotational load, while the OEM-fit hub pattern makes installation straightforward. Available in five colors to match your build.

Highlights

  • Directed Airflow — Blade geometry pushes cooling air through the shroud for steadier temps.

  • Lightweight Spin — 38.5 g helps reduce rotating mass for crisp response.

  • Color Options — Yellow / Green / Blue / Red / Orange.

  • OEM-Fit Hub — Matches stock flywheel/rotor mounting for a clean install.

  • Daily-Ride Ready — Built to handle heat cycles in commuting and hill climbs.
