After equipping my 2025 Yamaha MT‑09 with the Rapid Bike Racing2 Tuning Kit, the transformation was striking—right from the first ride. This isn't merely a tuning upgrade; it's a full reimagining of the bike’s responsiveness and adaptability.

From the moment the ignition fired up, the MT‑09 felt sharper and more controlled. The kit’s faster microprocessor, paired with a lighter and more compact design, immediately delivered smoother and more reliable performance when compared to the older unit. What’s more, it skillfully handles both Narrow‑Band and Wide‑Band O₂ sensor signals—a sophisticated capability that ensures the ECU never detects an unnatural tune.
One of the standout features is the digital multipoint fuel management paired with an auto‑adaptive system. The kit dynamically adjusts the fuel map in real time based on readings from the stock O₂ sensor. Whether riding through different altitudes, weather conditions, or after adding performance modifications, the MT‑09 always felt properly tuned—no dyno, no hassle.
When it came to deceleration and cornering, the engine-brake management was a revelation. Rear-wheel hopping became a thing of the past, replaced by a smooth, stable carry-through of curves—even under aggressive braking.
Another highlight: the intuitive smartphone app, which offers three distinct riding modes—Eco, Touring, and Sport—each with 20 finely tunable intensity levels. Perfect for switching between fuel-saving commuting, balanced street cruising, or aggressive spirited rides.
The kit also includes valuable diagnostic features, enabling me to read and clear ECU error codes directly from my phone—an elegant touch that enhances usability.
On the technical tuning front, the Racing2 retains and expands upon EVO’s capabilities with advanced spark‑advance management and crankshaft phase signal handling—key components for precise injection and ignition control.
For riders looking to push performance further, the optional YouTune controller unlocks a host of live-adjustment features: traction control, launch control, cruise limiter, quick‑shift tuning, AFR targeting, and more—directly accessible via handlebar-mounted controls.

I recently installed the Rapid Bike Racing2 Tuning Kit on my 2025 Yamaha MT‑09, and it has truly transformed its character. The new Racing2 module is lighter and faster than its predecessor and introduces responsive signal modulation in both Narrow Band and Wide Band—making throttle response feel immediate and reliable.

What really impressed me is the new smartphone app. It lets me choose between Eco, Touring, or Sport riding modes, each adjustable across 20 intensity levels. This flexibility lets me dial in performance, fuel efficiency, or balanced city riding on the fly.

Even more impressive is the auto‑adaptive fuel mapping. It continuously reads the stock O₂ (lambda) sensor signal and adjusts injection in real time based on riding conditions—never disappointing, whether I'm cruising or pushing hard.

Another standout is the engine brake management built into the kit. It smooths out deceleration, eliminating rear-wheel hopping and delivering far more controlled, confident cornering.

The Racing2 doesn’t stop there—it also includes advanced ignition mapping, allowing precise control over spark timing. And if you add the optional YouTune accessory, you unlock even more goodies: traction control, launch control, cruise limiter, real-time AFR tuning, adjustable quick‑shift timing, and more—all accessible via the handlebar-mounted controller.

Installation was surprisingly straightforward, and now that it's mounted, my MT-09 feels sharper, more responsive, and perfectly tuned for any scenario. Whether I’m looking to squeeze out every ounce of performance or smooth out a daily commute, this kit delivers.

Summary:

Responsive, lightweight Racing2 module with Narrow/Wide Band support

Smartphone app with three ride modes and 20 intensity levels each

Real-time auto-adaptive tuning for changing conditions

Engine-brake management for safer, smoother deceleration

Advanced ignition mapping—and even more features unlocked with YouTune

If you're looking to elevate your MT-09 performance and flexibility, the Racing2 kit is the perfect upgrade. Highly recommended!

I recently installed the Rapid Bike Racing2 Tuning Kit on my 2025 Yamaha MT‑09, and I must say—it’s a game-changer. The advanced microprocessor is noticeably faster and more compact compared to the older Racing model, while support for both Narrow Band and Wide Band tuning ensures smoother and more reliable operation

Installation was straightforward enough, and once plugged in, I appreciated features like multiple map management, RPM shifting (up to +1,000 rpm), and the option to remove the speed limiter—all of which significantly enhance the riding experience
. The diagnostic function is another bonus—it spotted and cleared minor ECU error codes that I hadn’t even noticed
If there’s a drawback, it’s that you’ll need to pair it with the optional YouTune controller to unlock real-time parameter tweaks and engine braking customization—but once set up, these functions elevate handling and stability, especially when decelerating aggressively
Overall, this tuning kit lives up to its reputation of unlocking your bike’s true potential. Whether optimizing for efficiency or performance, the Rapid Bike Racing2 delivers tight control and effortless adaptability. Highly recommended for anyone looking to take their MT-09’s rideability to the next level.
