81kW+ Performance
The VTB Ryuga is built for riders pushing the Sur-Ron Ultra Bee far beyond stock performance.
When paired with the VTB AETOS V9600 Controller and an appropriately rated high-output battery, the Ryuga is capable of delivering more than 81kW of power.
That’s over 108 horsepower equivalent from an Ultra Bee motor platform.
The result is massive acceleration and power delivery intended for serious high-performance builds.
114 Nm of Torque
With up to 114 Nm of motor torque, the Ryuga provides the immediate low-end and mid-range response expected from a competition-oriented electric powertrain.
The combination of high torque and massive power capability makes it suitable for riders building Ultra Bees for aggressive acceleration, racing, and other high-performance applications.
Hairpin Motor Technology
The Ryuga utilizes an advanced hairpin winding design engineered to support high current, increased power density, and efficient heat management.
Hairpin winding technology allows the stator to use precisely formed conductors rather than conventional round-wire winding methods, helping optimize conductor density within the motor.
For high-output applications, this architecture provides the foundation needed to support the Ryuga’s extreme performance capability.
Plug-and-Play Ultra Bee Fitment
Unlike motor upgrades that require fabrication or extensive chassis modifications, the VTB Ryuga was engineered specifically around the Sur-Ron Ultra Bee platform.
The motor installs as a direct replacement with no motor-mount or frame modifications required.
Fitment: Sur-Ron Ultra Bee
Pair With the VTB AETOS V9600
For maximum performance, pair the Ryuga with the VTB AETOS V9600 Smart Controller.
The V9600 provides the current capability and advanced motor control required to unlock the Ryuga’s high-output potential while allowing extensive tuning of throttle response and power delivery.
Recommended Performance System
VTB Ryuga Hairpin Motor + VTB AETOS V9600 Controller + High-Output Battery
Your battery, BMS, wiring, connectors, and supporting components must be capable of safely supplying the power demanded by the controller and motor.
Built for Extreme Ultra Bee Builds
The Ryuga isn’t designed as a mild stock replacement. It’s built for riders looking to transform the Ultra Bee into a significantly more powerful machine.
Whether you’re building for racing, acceleration, or maximum performance, the Ryuga provides the motor architecture needed to push the Ultra Bee platform into serious power territory.
Important
The 81kW+ output requires the appropriate controller, battery, BMS, wiring, connectors, tuning, and supporting components. Installing the motor alone will not produce maximum advertised power.
Actual output will vary depending on battery voltage, available battery current, controller configuration, temperature, gearing, drivetrain configuration, and other operating conditions.
High-power builds place significantly greater loads on the drivetrain, brakes, suspension, tires, electrical system, and other vehicle components. Professional installation and proper system configuration are strongly recommended.
