Rated performance
Ventus lists 60.3kW peak at 72V and 81kW at 96V. Output depends on the complete electrical system and tune.
Plan the complete upgrade
Choose a compatible controller and battery before installation. The motor alone does not deliver the advertised peak power on every setup.
Fitment source: Ventus Ryuga motor comparison. Checked September 22, 2026. Manufacturer-listed compatibility; not a Modded Moto Co installation test.
