Talaria MX3, MX4, MX5 & XXX: Which Nucular P24F Kit Fits Your Bike
Match the kit to the bike
Talaria has released enough closely-named models that ordering the wrong controller kit is an easy mistake. The harnesses differ between platforms, so a kit for one model will not simply plug into another. This page matches each bike to the right kit.
Every kit here is built around the Nucular P24F — intelligent FOC, 48V to 78V, 27kW maximum power. What changes between kits is the wiring that connects it to your bike's factory loom.
Talaria Sting, MX3, MX4 and MX5
These four share a kit: the Nucular P24F Talaria MX3 / MX4 / MX5 Upgrade Kit at $850.
What to expect:
- On the standard 60V battery: up to 30% more power.
- On a 72V battery (MX3 and MX4): up to 300% more power.
The kit also enables field weakening, which raises top speed by letting the motor spin past its normal voltage-limited ceiling.
Talaria XXX
The XXX has its own kit: the Talaria XXX High Power Upgrade Kit at $825.
Same pattern — up to 30% more power on the standard 60V pack, up to 300% on 72V, with field weakening for additional top-end speed.
Sur-Ron Light Bee and Segway X260
If you are cross-shopping, or you have a Segway X260 rather than a Talaria, the Sur-Ron Light Bee / Segway X260 kit is $850 and adds roughly 2,000W on the stock battery — about 20–30% more acceleration.
The 60V versus 72V gap is the whole story
Look again at those figures. Same controller, same kit: up to 30% more power on a 60V pack, up to 300% on 72V.
That tenfold difference in outcome is not marketing inconsistency — it is the battery being the real constraint. The stock 60V pack can only deliver so much current regardless of what is asking for it. The controller is not the limit; the cells are.
Two practical conclusions:
Do the controller first. Even on the stock pack you get a worthwhile gain, and you have unlocked the ability to use a better battery later. Going the other way — big pack, stock controller — gets you far less, because the factory controller simply will not draw the current.
Be realistic about the 300% figure. That is the headline number on a 72V pack under favourable conditions. It is real, but it is a peak, and reaching it means having a battery that can sustain the draw.
Before you order
Confirm your exact model. Sting, MX3, MX4, MX5 and XXX are not interchangeable for kit purposes. If you are unsure, send us your model year and a photo of the controller area and we will confirm.
Budget for programming. Every P24F needs either the Nucular On-Board Computer display ($130–$150) or the Bluetooth module ($35) to configure. Without one you cannot tune the controller.
Think about the rest of the bike. A 30% power increase is noticeable. A 300% increase changes the machine entirely. Brakes, tyres and suspension that were adequate at factory output may not be. Check pad thickness and tyre condition before the first hard ride, not after.
Know where you will ride it. These are off-road machines in most jurisdictions, and a substantial power increase does not improve their legal standing.
Setting it up
The defaults are deliberately conservative. Most of the gain comes from setting current limits appropriate to your motor's thermal capacity and tuning field weakening to your gearing. If you are not confident doing that, talk to us before you start raising numbers — setting a build up correctly is much cheaper than replacing a cooked motor.
