aRacer RC Mini XX - Yamaha Zuma 125 (2022+)

The aRacer RC Mini XX is the newest powerhouse in the Mini line, and now it's here for the latest 2022+ Yamaha Zuma 125. This is a true standalone ECU — not a piggyback. It completely removes your stock computer and hands you full control of how your scoot runs, tuned right from your phone over built-in Wi-Fi.

The Mini XX isn't just an update, it's a full evolution. It's built around a next-generation 4-core, dual-MCU architecture that's roughly 25% faster than the outgoing Mini X, paired with an advanced Gallium Nitride (GaN) driver module for cleaner, more efficient power delivery. Connect over Wi-Fi from your phone, tablet, or laptop, monitor all your engine vitals live, and make changes on the fly through aRacer's X-TUNE app.

Software gets a big step up too. The Mini XX debuts aRacer's Gen2 intelligent Auto-Tuning — when paired with the aRacer AF3 module, it delivers faster, more precise air/fuel correction so you can dial your tune in with confidence. It even adds a traction control (TCS) function the factory Zuma never had — flip it on for more controlled starts in the wet.

Whether you're running a big bore, upgrading injectors, or just want your Gen 3 Zuma to run right, the Mini XX gives you the headroom to tune it properly.
