Remote Speed Limiter Switch – Relay Module for Sur-Ron and Talaria

The remote speed limiter switch is a wirelessly controlled relay and switch module built for Sur-Ron and Talaria electric motorcycles, electric scooters and e-bikes. It connects or disconnects the speed limiting input on your controller. As a result, you activate ECO / 25 km/h mode or return to full power mode. The set includes the module itself and a remote fob.

Understanding the working principle matters most here. This module does not limit speed on its own, and it never reprograms your controller. Instead, it simply activates the limit your controller already has built in. Therefore, the final result depends entirely on your controller logic.

The module wires into the control circuit, not into the high-current power line. Because of that, it suits low-current control wiring or relay coil switching. In addition, you can use it as a straightforward remote switch for other circuits on your bike.

Key Benefits

• Remote speed limiting – switch into ECO / 25 km/h mode with a single button on the fob.
• Works with factory electronics – it uses the speed limit your controller already supports.
• Remote on and off control – the module doubles as a switch for a low-current control line.
• Relay coil control – drive the coil of a separate power relay through this module.
• Low-current connection – it connects to the controller limiting input wire, never to high-current power.
• Fast mode switching – handy in town, on trails and inside speed restricted zones.
• Broad application – suits controllers with ECO, speed limit or street/legal functions.
• Two-part set – module plus remote fob, so you never hunt for a controller separately.

Who Is This For?

This module is made for Sur-Ron and Talaria electric motorcycles running factory controllers. Moreover, it fits electric scooters and e-bikes whose controller has an ECO or speed limiting input. Compatible controllers are those with a separate limiting, street/legal or similar function.

If your controller has no such input, the module still works as a remote switch according to your own wiring diagram. For that reason, it pays to identify your exact controller model before you buy. A quick check of the wiring harness usually confirms whether the input exists.

This solution suits riders who move between different zones. For example, you enable limited speed mode in the city, then restore full power outside town. The module also helps when several riders share the same bike.

What’s in the Box?

• Remote controlled module (relay / switch)
• Remote control fob

Technical Specifications

Why Choose This Remote Speed Limiter?

The main difference is simplicity. This module changes no factory firmware and reprograms nothing inside the controller. It only toggles the limit your controller already carries. Consequently, the installation stays reversible and low risk.

The second difference is where you control it from. You change the mode with the fob, so you never reach into the electronics or open the wiring harness. Furthermore, the plain switch function still works on controllers that lack a limiting input.

If you would rather set any speed yourself and remove the limit with one press on the handlebars, consider the FabiRide Dash Pro. That display works with factory Sur-Ron and Talaria controllers. It lets each rider define a personal limit without changing anything on the bike.

Frequently Asked Questions

Will this module create a 25 km/h limit?

• Yes, provided your controller has an ECO or speed limiting input that a wire can activate.
• The module does not limit speed by itself. It only triggers the limit the controller already holds.
• The final outcome therefore depends on your controller logic.

Does the module fit Sur-Ron and Talaria motorcycles?

• Yes. It is designed for Sur-Ron and Talaria electric motorcycles with factory controllers.
• It also fits electric scooters and e-bikes with a suitable limiting input.

Can I use it on a Sur-Ron if my controller has no ECO input?

• Yes, but only as a remote switch within your own wiring layout.
• Speed limiting will not activate without a dedicated limiting input.

Where exactly does the module connect?

• It connects to the controller limiting input wire in the control circuit.
• Never wire it into the high-current power line.
• You can also use it to switch a separate power relay coil.

Does it reprogram my Talaria controller?

• No. The module leaves factory software untouched.
• It simply connects or disconnects the chosen control wire.

What comes in the set?

• The remote controlled relay / switch module.
• The remote control fob for mode changes.

Can several riders share one bike with this fitted?

• Yes. You can enable limited mode for one rider and restore full power afterwards.
• Each change takes one button press on the fob.

Can I use it as a general remote switch?

• Yes. It suits any low-current control line on your build.
• It also drives the coil of a separate power relay.

This remote speed limiter gives Sur-Ron and Talaria riders a simple way to move between ECO and full power. It uses your existing controller function and adds a fob for instant mode changes. In short, you get city-legal behaviour when you want it and factory performance when you do not.
