EBMX X-9000 Controller Upgrade Kit

The EBMX X-9000 Controller Upgrade Kit is widely considered the pinnacle of aftermarket powertrain control for electric off-road motorcycles. Designed and engineered from the ground up in Australia specifically for high-performance e-moto applications, the X-9000 transforms your Sur-Ron from a factory trail bike into a high-output competition machine with unprecedented power delivery, thermal stability, and fine-tuning control.

Built around high-efficiency 32-bit Field-Oriented Control (FOC) sinusoidal architecture and VESC-based firmware, the X-9000 operates across a massive 40V to 110V input range. It is fully plug-and-play with the stock 60V battery (safely unlocking up to 7–8kW of smooth power) and capable of managing up to 1000A peak phase current when paired with high-voltage 72V aftermarket battery packs.

Housed in a rugged, CNC-machined finned billet aluminum enclosure sealed to IP67 waterproof standards, the X-9000 features an internal multi-axis IMU (Inertial Measurement Unit) for advanced functions like traction control and wheelie assist. The integrated Bluetooth module pairs seamlessly with the EBMX smartphone app (iOS/Android), giving riders real-time telemetry, OTA firmware updates, and granular adjustment of throttle curves, field weakening, and regenerative braking.

Hardware & Thermal Engineering: The X-9000 utilizes 30 high-grade Infineon 120V MOSFETs mounted to a multilayer PCB with solid copper CNC busbars for low internal resistance. The finned aluminum casing functions as an active convective heatsink, dissipating thermal load during prolonged full-throttle hill climbs.

Installation & Calibration Guidelines: Always turn off the main circuit breaker and disconnect the battery before installation. Mount the controller to the frame, connect the OEM-matching waterproof wiring loom, and torque the phase ring terminals (U, V, W) to 8–10 Nm. Elevate the rear wheel off the ground and run the Hall sensor auto-calibration routine in the EBMX mobile app before riding.

Companion Upgrades: When upgrading to high power outputs on the X-9000, pair the controller with an EBMX Gold Race Chain & Sprocket Kit, a heavy-duty DC circuit breaker, and an upgraded high-discharge 72V battery pack.

Frequently Asked Questions:

Q: Can I run the EBMX X-9000 controller with a stock 60V Sur-Ron battery? A: Yes. The X-9000 includes pre-loaded profiles tuned specifically for the factory 60V battery, optimizing torque delivery while respecting stock BMS limits.

Q: What is the maximum operating voltage of the X-9000? A: The X-9000 supports an operating voltage range of 40V to 110V (up to 26S lithium configurations), making it compatible with 60V, 72V, and 81V battery packs.

Q: How does the EBMX smartphone app connect to the controller? A: Built-in Bluetooth provides seamless wireless connectivity for live telemetry, throttle curve customization, regen braking adjustment, and over-the-air firmware updates.

Q: Is the X-9000 controller waterproof for wet and muddy riding? A: Yes. The CNC billet enclosure is fully sealed to IP67 standards with automotive-grade sealed harness connectors.

Q: What torque should be used on the motor phase wire terminals? A: Torque the M6 phase terminal bolts to 8–10 Nm using a calibrated torque wrench. Never over-torque or leave terminals loose.

Thermal Dissipation & Multi-Layer PCB Architecture: The X-9000 controller's internal multilayer printed circuit board utilizes heavy copper pours and solid copper busbars to minimize internal resistance. When conducting continuous high phase current during hill climbs, heat is conducted directly into the CNC billet housing and dissipated into passing airflow.

Over-Current Protection & Sensor Redundancy: The X-9000 features hardware-level over-current protection that responds in microseconds to prevent MOSFET damage during sudden mechanical jams or phase shorts. Support for dual temperature sensors protects both motor stator windings and controller silicon simultaneously.
