Installing the Rapid Bike Racing2 kit on my 2023 Kove 450 Rally was a breeze. The kit comes with a compact and lightweight Racing2 ECU, a model-specific plug-and-play waterproof wiring harness, and clear instructions that made the install smooth and hassle-freeOnce installed, the magic really unfolds through the smartphone app. I can choose between Eco, Touring, and Sport modes—each offering 20 intensity levels. Whether I'm conserving fuel on long rides, cruising through mixed terrain, or chasing adrenaline on tight trails, it's just a few taps to dial in the perfect ride.
What truly stands out is how the Racing2 handles lambda sensor signal management (both narrow-band and wide-band). It dynamically updates the fuel map while you're riding, thanks to its auto-adaptive function. The result? Noticeably smoother throttle response, especially in low- and mid-RPM ranges, with virtually zero hesitation—even when riding through changing elevation or shifting conditions.
On top of that, the kit brings advanced features often reserved for track bikes. It supports electronic shifters (optional), dual map management, RPM shifting of up to +1000 rpm, and even the ability to remove the speed limiter. If your bike has twin lambda sensors like mine, this kit can create independent maps and auto-correction for each cylinder—genius engineering.
Want even more control? Pair this with the YouTune controller, and you'll instantly unlock real-time management of self-remapping injection parameters, fine-tuning of engine brake for smoother deceleration, refined electronic shifter timing, a managed speed limiter, and even handy real-time engine data display

Installing the Rapid Bike Racing2 tuning kit on my 2023 KOVE 450 Rally was hands-down one of the best upgrades I’ve made. This isn't just another ECU mod—it’s a performance brain upgrade. The kit comes with a compact Racing2-specific ECU, plug-and-play wiring harness, and clear mounting instructions. Everything fit perfectly, and the install was done in less than an afternoon.
Once I paired it with the smartphone app, I understood why this kit stands out. You get three ride modes—Eco, Touring, and Sport, each offering 20 intensity levels. Switching from long-haul fuel-saving mode to dialing-in throttle response on remote desert tracks is effortless and intuitive.
But the real magic is the self-adaptive ECU logic. The Racing2 actively manages both Narrow‑Band and Wide‑Band O₂ sensor signals to continuously update fuel mapping while I'm riding. The result? Smooth throttle response, zero hesitation—even when riding across varied terrain or changing elevation.
Racing-level features make this kit feel seriously next-level. It includes advanced spark-advance mapping, engine‑brake control for stability in corners, and a dual-map switching feature so I can toggle between customized presets on the fly. Pair it with the optional YouTune accessory, and you unlock traction control, launch control, and even a pit-lane limiter, all adjustable in real time.

I recently installed the Rapid Bike Racing2 tuning kit on my 2023 KOVE 450 Rally, and I’m stunned by the transformation. The kit includes a compact Racing2 ECU, a model-specific, plug-and-play waterproof wiring harness, and straightforward mounting instructions—installation was surprisingly seamless, even in my home garage
Once I fired it up, the difference was immediately noticeable. The Racing2 kit intelligently handles both narrow‑band and wide‑band O₂ sensor signals, enabling adaptive, real-time fuel mapping. It dynamically adjusts the injection maps mid-ride, smoothing throttle response, eliminating hesitation, and giving better power delivery throughout the rev range.
Since my bike has a twin-cylinder engine with two O₂ sensors, the kit even fine-tunes fuel on a per-cylinder basis—truly impressive.
But that’s not all—this kit injects a dose of race-level sophistication. It manages spark advance dynamically, extends injector flow beyond factory limits by +1000 rpm, and intelligently controls engine braking for smoother deceleration when connected to the optional YouTune accessory.
