PowerTRONIC V4 ECU for Yamaha XSR 125 (2021-2022)

🏍 Product Description :

Upgrade your Yamaha XSR 125 with the advanced PowerTRONIC V4 Piggyback ECU — engineered to deliver sharper throttle response, stronger mid-range acceleration, and improved top-end performance.

Designed specifically for the 2021–2022 Yamaha XSR 125, this plug-and-play ECU installs within minutes and enhances performance using race-developed, user-adjustable fuel and ignition mapping. With the Tune Easy smartphone app, you can tune, calibrate, and optimize your bike anytime, anywhere.

PowerTRONIC eliminates stock part-throttle hesitation and improves transient throttle response in closed-loop conditions. Whether riding in city traffic or cruising open roads, your XSR 125 becomes more responsive, smoother, and more enjoyable to ride.

The preset 12,000 RPM rev-limit (expandable up to 15,000 RPM for race setups) widens the usable powerband, increases in-gear acceleration, improves top-speed potential, and reduces unnecessary gear shifts — keeping your engine in its optimal performance zone longer.

Advanced ignition control algorithms ensure power delivery remains strong yet refined, minimizing engine vibrations while maximizing riding excitement.

If you want your Yamaha XSR 125 (2021–2022) to feel quicker, smoother, and more performance-focused, PowerTRONIC V4 is the ultimate ECU upgrade.
