Ventus Ryuga 52kW Motor | By Ventus Bikes VTB | For Sur Ron, Talaria, E Ride Pro, and EMoto Platforms
Overview
The Ventus Ryuga 52kW Hairpin Motor is built to transform lightweight EMoto platforms into true performance machines. Paired with the VTB Aetos V9600 controller and a high-capacity battery, the Ryuga delivers explosive acceleration, instant throttle response, and high-rpm stability that stays predictable even under heavy load.
This next-generation VTB motor uses a high-efficiency hairpin winding design, precision engineering, and durable construction to deliver power levels usually found only in full-size electric motorcycles. With up to 52.5 kW peak output and 91 Nm of torque, the Ryuga sets a new standard for Sur Ron, Talaria, E Ride Pro, and other compatible EMoto frames.
