EBMX X-9000 Controller Upgrade Kit

The EBMX X-9000 is the industry-standard controller upgrade for Sur-Ron Light Bee X and Ultra Bee owners who want to unlock the full potential of their electric dirt bike. This plug-and-play controller replaces the stock unit and immediately unlocks 9000W of peak power output, nearly doubling the factory power rating.

Programmable via the free EBMX Bluetooth smartphone app, riders can fine-tune throttle response curves, set maximum speed limits, configure regenerative braking strength, and monitor real-time telemetry including motor temperature, battery voltage, and power consumption. Three customizable riding profiles can be saved and switched on the fly.

The X-9000 features a waterproof CNC-machined aluminum enclosure with integrated heat sink fins for superior thermal management during extended high-power riding. All factory connectors are retained for true plug-and-play installation with no wire cutting required. Average install time is under 30 minutes with basic hand tools.

Compatible with stock 60V batteries and aftermarket packs up to 84V. Includes regenerative braking support, reverse mode, and cruise control functionality. This is the single most popular Sur-Ron upgrade for a reason: it transforms a fun trail bike into a competition-grade machine.
