The ASI BAC8000 controller upgrade kit is a complete power package built for the Talaria Sting electric dirt bike. It replaces the factory controller with an ASI BAC8000 sinusoidal FOC controller, a purpose-made wiring harness, a display, controller brackets and a heatsink. Peak output reaches 15,000 W (18 kW) on a 72 V battery.
A stock Talaria Sting motor runs at roughly 6 kW. Swapping the factory controller for the BAC8000 raises output by 180-300% with battery bypass. Paired with a custom 60 V or 72 V battery, the gain climbs to 300-600%. As a result, torque and acceleration at the rear wheel increase dramatically.
Installation is plug-and-play. There is no soldering and no cutting or modifying the bike. You simply unplug the original controller and connect the new one. In addition, every buyer receives a personal remote tuning session with our engineer.
Key Benefits
- Up to 15 kW of power – roughly three times the output of a stock Talaria Sting.
- Individual tuning – an engineer configures the controller remotely around your riding style instead of leaving factory presets in place.
- Reverse gear – the red button on the original Talaria throttle grip is reprogrammed as a reverse switch.
- Motor temperature protection – the system tracks motor temperature and cuts power before overheating occurs.
- Battery sag protection – output is reduced automatically once the battery charge drops.
- Power adjustment from the display – you change the power level directly on the screen, without a computer.
- Assist level in percent – throttle response is tuned in percentage steps to suit the trail.
- Custom wiring harness – built specifically for Talaria Sting connectors, so nothing needs reworking.
Who Is This Kit For?
This kit is made for the Talaria Sting electric dirt bike. That is a pedal-less electric motorcycle competing in the Sur-Ron Light Bee class. It is not intended for electric bicycles or scooters.
The package suits riders who have outgrown the stock ~6 kW output off-road. Above all, it shines on downhill trails, sand pits and technical motocross sections. The torque increase is felt immediately at the rear wheel.
The controller works with the original OEM Talaria battery as well as with upgraded 60 V or 72 V packs. Therefore you can fit the kit now and upgrade the battery later. The kit is intended for closed courses and off-road use, and fitting it voids the factory warranty.

Why Choose This BAC8000 Upgrade Kit?
Many power kits ship with pre-loaded settings and nothing more. Here, each controller is tuned individually during a remote session. The engineer also checks the installation you have carried out.
ASI (Accelerated Systems Inc.) builds the BAC8000 as a sinusoidal field-oriented control unit. Consequently, power delivery stays smooth rather than abrupt, which matters on loose and technical ground. The heatsink and brackets are included, so thermal management and mounting are handled out of the box.
Furthermore, the harness is made for Talaria Sting connectors specifically. That keeps the fitting time short and avoids splicing into the factory loom.
Frequently Asked Questions
Does the BAC8000 kit fit any Talaria model?
- The kit is designed for the Talaria Sting.
- The harness matches Talaria Sting connectors directly.
- It is not made for electric bicycles or scooters.
How much power does the Talaria Sting gain?
- Stock output is around 6 kW.
- With bypass, the gain is 180-300%.
- With a 60 V or 72 V custom battery, the gain reaches 300-600%.
- Maximum output is 15,000 W (18 kW) on 72 V.
Do I need to modify the bike or solder anything?
- No. The installation is plug-and-play.
- You remove the original controller and plug in the new one.
- Brackets and a heatsink are supplied for mounting.
Can I keep the original Talaria battery?
- Yes. The controller runs on the OEM Talaria pack.
- It also supports upgraded 60 V and 72 V batteries.
- You can fit the kit first and upgrade the battery later.
Which display is included?
- You choose either the 750C or the EggRider V2.
- Both allow power and assist level adjustment.
- Wheel size and km/h – mph units are also set there.
How does the reverse function work?
- The red button on the original throttle grip is reprogrammed.
- It then acts as a reverse switch.
- No extra switch or wiring is required.
What does the remote tuning session include?
- An engineer configures the controller for your riding style.
- The same session covers a check of your installation.
- Settings are matched to your battery option.
Is the kit road legal?
- It is intended for closed courses and off-road riding.
- Fitting the kit voids the factory warranty.
The ASI BAC8000 upgrade kit turns a stock Talaria Sting into a machine with up to 18 kW on tap, individual tuning and built-in motor and battery protection. Everything needed for the swap is in the box: controller, harness, display, brackets and heatsink.
