ASI BAC Wiring Harness for Talaria Sting MX3 / MX4 with Encoder to Hall Converter

The ASI BAC wiring harness for Talaria Sting is a plug-and-play loom built for the Talaria Sting MX3 and Talaria Sting MX4 electric dirt bikes. It links an ASI BAC4000 or ASI BAC8000 controller to the factory Talaria system. An encoder to Hall sensor signal converter is included in the box.

This harness exists for one job: the controller swap. You remove the stock Talaria controller and fit a stronger ASI BAC unit in its place. Because every plug matches the factory side, no original bike wire needs cutting or soldering. All connectors are keyed and cut to OEM lengths.

The stock Talaria motor reports position through an encoder, while ASI BAC controllers expect Hall sensor signals. The included converter translates between the two. As a result, launches stay steady and start-up cogging is noticeably reduced. The loom also works with APT 750C and Eggrider V2 displays.

Key Benefits

• Plug and play fitment – connects straight to the factory Talaria Sting connectors with no modification.
• No soldering required – installation needs no soldering iron and no wire cutting.
• OEM cable lengths – wire runs match the factory loom, so cable routing stays tidy.
• Encoder to Hall converter included – the ASI controller reads the stock motor position correctly.
• Two controllers, one harness – the same loom fits the ASI BAC4000 and the ASI BAC8000.
• Display support – works with APT 750C and Eggrider V2 dashboards.
• Low resistance contacts – quality terminals keep losses at the connections minimal.
• Reverse polarity protection – mechanical keying prevents connectors from being joined the wrong way.

Who Is This Harness For?

This loom is made for owners of the Talaria Sting MX3 and the Talaria Sting MX4. Both are electric dirt bikes. The harness is therefore not intended for e-bikes or scooters.

Supported controllers are the ASI BAC4000 and the ASI BAC8000. Both are field oriented control units, though their current ratings differ. The harness fits either one. Tuning parameters, however, must be selected to match the specific controller you install.

Officially supported displays are the APT 750C and the Eggrider V2. The Eggrider V2 additionally allows controller tuning over Bluetooth. In short, this product suits riders doing a power upgrade themselves or in a workshop.

What’s in the Box

• 1× Talaria to ASI BAC wiring harness
• 1× encoder to Hall sensor signal converter, matched to Talaria sensors

Technical Specifications

Installation Steps

• Disconnect the battery and remove the factory controller.
• Connect the harness to the ASI BAC and to the Talaria connectors.
• Fit the encoder to Hall module between the motor sensor and the controller.
• Install your display: APT 750C or Eggrider V2.
• Route the cables neatly, then power the system up.
• Run a basic check of the BAC parameters.

Why Choose This Harness

The main difference from home-made looms is the signal converter supplied with it. Without that module, an ASI controller cannot read the stock Talaria motor position sensor. This harness therefore works with the OEM motor right away, with no motor swap needed.

The second difference is the keyed connectors. They mechanically block a reversed connection during installation. Furthermore, OEM lengths mean nothing has to be shortened or extended once the loom is in place.

Third, a single harness covers both ASI BAC models. Consequently, moving from a BAC4000 to a BAC8000 later requires no new wiring. That makes it a sensible buy for riders planning a staged power upgrade.

Frequently Asked Questions

Does the ASI BAC harness fit the Talaria Sting MX3?

• Yes. The loom is built for the Talaria Sting MX3 and MX4.
• The connectors match the factory Talaria Sting connectors.

Which controllers does this harness support?

• The ASI BAC4000 and the ASI BAC8000.
• Both are field oriented control units with different current ratings.
• Tuning parameters should be chosen for the controller you fit.

Will it work on a Talaria Sting MX4?

• Yes. MX4 fitment is covered by the same harness.
• No adapters or extra looms are needed.

Why is an encoder to Hall converter needed?

• The stock Talaria motor sends encoder signals.
• ASI BAC controllers expect Hall sensor signals instead.
• The included module translates between them, keeping launches stable and cogging low.

Do I have to cut or solder any wires?

• No. Installation is plug and play.
• Cable lengths follow OEM spec, so no shortening is required.

Which displays can I run?

• APT 750C and Eggrider V2 are officially supported.
• The Eggrider V2 also allows controller tuning over Bluetooth.

Can I connect a plug the wrong way round?

• No. Every connector is keyed.
• The keying mechanically blocks reversed connections.

Does this fit an electric bicycle or scooter?

• No. It is designed for Talaria Sting electric dirt bikes only.

For riders upgrading a Talaria Sting MX3 or MX4 to ASI BAC power, this FabiRide harness removes the hardest part of the job. The converter, the keyed plugs and the OEM lengths turn a wiring project into a straightforward controller swap.
