PowerTRONIC V4 ECU for Yamaha FZ 25 (2018-2021)

🏍  Product Description :

Upgrade your Yamaha FZ 25 with the advanced PowerTRONIC V4 Piggyback ECU — engineered to deliver sharper throttle response, stronger mid-range torque, and improved top-end performance.

Specifically designed for the 2018–2021 Yamaha FZ 25, this plug-and-play ECU installs within minutes and enhances performance through race-developed, user-adjustable fuel and ignition mapping. Using the Tune Easy smartphone app, you can tune, calibrate, and optimize your motorcycle anytime, anywhere.

PowerTRONIC significantly reduces stock part-throttle hesitation and improves transient throttle response in closed-loop riding conditions. The result is quicker pickup in city traffic, smoother acceleration, and stronger mid-range performance for highway rides.

With a preset 12,000 RPM rev-limit (expandable up to 15,000 RPM for race setups), PowerTRONIC widens the usable powerband, improves in-gear speeds, enhances top-end pull, and keeps the FZ 25 in its strongest torque zone longer — reducing unnecessary upshifts.

Advanced ignition control algorithms ensure smooth and predictable power delivery while minimizing engine vibrations, delivering enhanced performance without compromising refinement.

If you want your Yamaha FZ 25 (2018–2021) to feel sharper, stronger, and more responsive — PowerTRONIC V4 is the ultimate ECU upgrade.
