I recently installed the Rapid Bike Racing2 tuning kit on my 2024 KTM 890 Adventure R, and I’ve never ridden with such confidence and control. From the moment I unpacked it, I was impressed—it includes a compact Racing2 ECU, a model‑specific plug-and-play waterproof wiring harness, and clear mounting instructions.
Installation & Design
Installation was a breeze—even for a home mechanic like me. The lightweight, streamlined design and faster microprocessor make the Racing2 noticeably more advanced than its predecessors. I also appreciated the dual Wide‑Band and Narrow‑Band signal modulation capability—that means the system integrates seamlessly with the bike’s sensors without throwing error codes.
Performance & Adaptive Tuning
Once installed, the kit’s auto‑adaptive fuel mapping system grabbed my attention. It uses the stock O₂ (lambda) sensor signals to dynamically tweak fuel maps during rides—perfect for adapting to altitude changes, temperature shifts, or road conditions. No hesitation, no flat spots—just responsive, consistent power throughout the rev range.
App-Controlled Custom Modes
Pairing with the smartphone app was intuitive. I loved having three customizable modes—Eco, Touring, and Sport—each offering up to 20 intensity levels. Now I can easily flip from smooth, fuel-efficient cruising to aggressive, street-ready performance at a moment’s notice
Advanced Features with YouTune
The Racing2 alone is smart and powerful. Add the optional YouTune accessory, and things get next-level: refined engine‑brake control to keep the rear wheel planted in corners, traction control to help out on loose surfaces, launch control for slick starts, and even a pit-lane limiter if I ever need it.

Upgrading my 2024 KTM 890 Adventure R with the Rapid Bike Racing2 tuning kit was nothing short of revelatory. The kit arrived with a slick, compact ECU and a clearly labeled, plug-and-play harness—installation went smoothly and hassle-free. It felt like the engineering team cared about real-world simplicity.
Once installed, the real fun started. The Racing2 kicks things up a notch compared to the previous model thanks to a faster processor, reduced size, lighter weight, and the ability to modulate both narrow-band and wide-band signals for superior responsiveness. The whole system just feels more refined and reliable.
But where it truly shines is the intuitive smartphone app. With three customizable modes—Eco, Touring, and Sport—each offering up to 20 intensity levels, I can instantly tailor my ride to conserve fuel on long stretches, stay smooth during urban commutes, or dial up the thrill on twisty backroads.
The auto-adaptive fuel mapping, driven by real-time lambda (O₂) sensor data, is a game-changer. The system continuously self-tunes as conditions change—whether I'm climbing in elevation or shifting between hot and cold air. The low- and mid-RPM ranges feel especially polished—no more hesitation or bog when I needed smooth, predictable throttle response.
Beyond performance, the Racing2 brings track-level sophistication: you can hook up an optional electronic shifter, manage multiple maps, tune your shifts up to +1000 rpm, or even remove the speed limiter. And for twin-cylinder setups equipped with two lambda sensors (like mine), each cylinder gets its own map and fine-tuning—clever stuff.
For riders seeking even more control, the optional YouTune controller unlocks live tuning capabilities: engine braking adjustments for improved cornering stability, smoother speed limiter modulation, customizable shift cut timings, and real-time performance data on top of everything else.

As someone who splits my time between long desert rides and technical single-track, upgrading my 2025 KTM 890 Adventure R with the Rapid Bike Racing2 kit was a game-changer. The kit includes a dedicated Racing2 ECU, plug-and-play waterproof wiring harness, and clear instructions—making installation straightforward even for a home mechanic.
Once fired up, the system’s responsiveness was immediately noticeable. Thanks to its digital multipoint fuel management and handling of both narrow- and wide-band O₂ signals, throttle response feels refined and consistent across all RPMs. The self‑adaptive technology intelligently tweaks injection maps on the fly using real-time O₂ feedback, ensuring peak performance regardless of altitude, temperature, or terrain.
The intuitive smartphone app is where things get fun. With three modes—Eco, Touring, and Sport—each offering 20 intensity levels, tuning on the go is both instant and engaging. Whether I’m saving fuel on long haul stretches or dialing in aggressive power for tight corners, it’s effortless.

More impressively, the Racing2 adds advanced features often reserved for the track: dynamic spark advance, engine-brake management to maintain rear-wheel stability during aggressive decel, and the ability to switch between dual engine maps in real time. Add-on YouTune accessories can unlock the pit-lane limiter, traction control, and launch control—but even without it, this unit dramatically sharpens the bike’s behavior.

Riding now feels like the machine intuitively adjusts to my input and terrain—precise, confident, and fast. Corner exits are smoother, throttle response is laser-focused, and even during spirited ride-ups or technical climbs, the power remains clean and manageable.

If you’re serious about dialing your KTM 890 Adventure R for both trail and tarmac, the Rapid Bike Racing2 kit delivers pro-level performance in a rugged, user-friendly package. Highly recommended.

Installing the Rapid Bike Racing2 kit on my 2024 KTM 890 Adventure R was hands-down one of the best upgrades I’ve ever made. The plug-and-play ECU installed cleanly, and the waterproof wiring harness fit perfectly—props to Adventure Parts for making it virtually painless.
Once powered up, pairing the kit with its smartphone app opened up a whole new world. The ability to toggle between Eco, Touring, and Sport modes—and tweak each across 20 intensity levels—puts complete control at my fingertips. Whether I'm cruising long highway stretches or attacking gravel backroads, I simply dial in the right profile.
What took the experience to another level was the kit’s auto‑adaptive fuel mapping. Thanks to real-time O₂ sensor feedback (and support for dual sensors per cylinder), the system continually refines its tuning, adapting to changes in altitude or load seamlessly. No more bogs or flat spots—just consistently crisp throttle response.
Riding now feels both sharper and more refined. The engine pulls cleanly across the rev range, with smoother transitions and noticeably improved power delivery—even when decelerating, the engine brake management keeps things planted and stable.
Feature-wise, this kit is loaded: advanced fuel and spark management, upgrades to pick-up and crankshaft signal control, and diagnostics that read and clear original ECU faults. The optional YouTune accessory unlocks even more—traction control, launch control, dual-map presets, and even a pit‑lane limiter.
Sure, it’s an investment. But from highway touring to backside singletrack, the difference is palpable—in both performance and ride confidence. If you’re looking to truly enhance your KTM’s performance, the Racing2 kit delivers intelligently and reliably.
