KO Factory Spec Rush Controller – 60kW Upgrade

KO Factory Spec Rush Controller is a high-performance controller upgrade designed for serious Talaria and Sur-Ron builds that need substantially greater power capability, advanced tuning, and improved control over the electric drivetrain. Developed by KO Moto specifically for high-performance e-bike applications, the Rush Controller supports up to 600A maximum line current, 1800A maximum phase current, and up to 60kW peak output when the battery, motor, wiring, and overall build are capable of supporting those levels.

Built for High-Power Performance

The KO Factory Spec Rush Controller is designed for riders who want far more control over how their Talaria or Sur-Ron delivers power. Instead of being limited to a fixed factory calibration, the controller provides extensive tuning options so power delivery can be adjusted to match the battery, motor, riding style, and terrain.

With support for up to 600A line current and 1800A phase current, the Rush Controller provides the headroom required for demanding performance builds. The advertised 60kW peak capability is a maximum controller capability, not a guarantee that every bike will produce 60kW. Actual output depends heavily on the battery’s discharge capability, motor, wiring, voltage, cooling, and controller settings.

Advanced Power & Throttle Tuning

The KO control software gives riders extensive control over the way the bike responds. Depending on the configuration, users can adjust parameters including:

• DC battery current
• Phase current
• Throttle curves
• RPM and torque characteristics
• Acceleration response
• Regen braking strength
• Throttle voltage
• Power delivery characteristics
• Different riding tunes and power levels

This makes it possible to create a softer tune for technical riding or a much more aggressive setup for open terrain and high-performance riding. KO states that its software can be used through its PC software and mobile applications, with tuning designed to be accessible without additional paid software licensing.

Factory-Fit Design

One of the major advantages of the KO Factory Spec Rush Controller is its factory-fit approach. KO states that the controller is designed to use the stock mounting positions and connect directly to the standard bike cabling on supported Sur-Ron and Talaria applications. This helps simplify installation compared with systems that require extensive custom brackets or additional wiring.

Always verify the exact bike model, wiring, battery voltage, and connector configuration before installation.

CNC Heat Sink & Thermal Management

The Rush Controller uses a redesigned CNC-machined heat sink intended to improve heat dissipation during demanding riding. The controller housing is designed around high-power operation while maintaining an IP67 ingress-protection rating. KO lists an operating temperature range of approximately -25°C to 80°C and maximum efficiency above 95%.

Battery & Motor Requirements

The Rush Controller is a high-power component and should not be installed with the expectation that the controller alone will create its maximum advertised output.

Your battery must be capable of supplying the required current, while the motor must also be capable of handling the selected power level. KO specifically warns users to consider the performance limits of their motor and battery when using the controller.

For high-power configurations, the battery, BMS, connectors, cables, motor, cooling, and controller tune should all be selected as a complete system.

Why Upgrade to the KO Rush Controller?

The Factory Spec Rush Controller is a strong choice for riders building a high-performance Talaria or Sur-Ron who want:

• Much greater controller power capability
• Adjustable power delivery
• Custom throttle response
• Adjustable regenerative braking
• High phase-current capability
• High-voltage compatibility
• Factory-style mounting on supported applications
• CNC thermal management
• IP67 protection
• PC and mobile tuning capability

Whether you’re building a responsive trail setup or a much more aggressive performance build, the Rush Controller gives you significantly more tuning flexibility than a standard factory controller.

What’s Included?

The product is the KO Factory Spec Rush Controller.

Exact accessories, cables, communication hardware, and connector configuration can vary by application or package, so please verify the included items with the product listing before ordering.

Installation

The controller is designed for a factory-fit installation on supported Talaria and Sur-Ron applications. However, because this is a high-power controller, installation and initial configuration should be performed carefully.

Before applying maximum power, confirm:

1. Battery voltage is compatible.
2. Battery discharge capability is sufficient.
3. Motor specifications are appropriate for the intended power level.
4. Connectors and wiring are correctly installed.
5. Controller settings are configured for the battery and motor.
6. Throttle operation is checked before riding.
7. Temperature and system behavior are monitored during initial testing.

Incorrect controller settings or excessive current can damage the battery, motor, wiring, or other components.

Buyer’s Questions

What is the KO Factory Spec Rush Controller?

It is a high-performance programmable controller designed for Talaria and Sur-Ron electric bike builds, with advertised capability of up to 60kW peak power, 600A line current, and 1800A phase current.

Does it automatically produce 60kW?

No. 60kW is the controller’s advertised maximum peak capability. Actual power depends on the battery, BMS, voltage, motor, wiring, cooling, and controller configuration.

Can I use it with a stock battery?

It may be possible to operate a controller with a stock battery at an appropriate reduced tune, but you should not assume the stock battery can support high-power settings. Battery discharge capability must be verified before increasing current.

Can I use a 72V battery?

The controller’s published voltage range supports high-voltage configurations, including 72V-class battery systems. The battery and controller configuration must be correctly matched before operation.

Can I tune the controller?

Yes. KO provides software that allows adjustment of power delivery, current, throttle characteristics, regen, and other parameters.

Is it waterproof?

KO lists the Rush Controller with an IP67 ingress-protection rating.

Will it fit my Talaria?

The Rush Controller is designed for supported Talaria and Sur-Ron applications, but exact compatibility should be confirmed for your specific model and wiring configuration before ordering.

Do I need a bigger battery to use this controller?

Not necessarily to operate it at a conservative setting, but a high-power battery is required to take advantage of the controller’s higher-current capabilities.

Is this a beginner upgrade?

The controller is capable of very high power and is better suited to riders who understand battery, motor, current, and controller tuning. Incorrect settings can cause component damage.

Can the controller damage my motor?

Yes, if configured beyond what the motor can safely handle. High controller capability does not mean the motor should automatically be operated at maximum current.

Who is this controller for?

It is best suited to riders building high-performance Talaria or Sur-Ron setups who want extensive tuning capability and significantly more controller headroom than a stock system.

Important: High-power upgrades should be configured as a complete system. Always match the controller settings to the battery, BMS, motor, wiring, connectors, and cooling system rather than simply selecting the maximum available current.
