I just fitted the Rapid Bike Racing2 kit on my 2024 Kove 800X Pro, and I’m genuinely floored—it’s like the bike grew a brain. The installation was impressively straightforward: the kit includes a compact Racing2 ECU, model-specific plug-and-play waterproof wiring, and clear mounting instructions. I had everything up and running in under an afternoon
Once I paired it with the app, the whole experience transformed. The Racing2 offers three riding modes—Eco, Touring, and Sport—each with 20 levels of intensity. Whether conserving fuel on long highway stretches, cruising around town, or pushing hard on gravel and trails, dialing the throttle feel is instantaneous and intuitive.
But the real magic lies under the hood. The kit handles O₂ sensor signal management (both reading and modulation) to dynamically fine‑tune fuel injection via a digital multipoint system, adapting on-the-fly to riding conditions for consistently smooth, sharp throttle response. And, since the Kove’s twin-cylinder engine uses two O₂ sensors, the Racing2 can adjust each cylinder individually—brilliant.
For those who demand precision control, the Racing2 goes beyond fueling. It features spark advance tuning, engine-brake management for smoother decel and cornering stability, and even supports dual map presets, so I can switch between setups in real time. Plus, with the optional YouTune accessory, you unlock traction control, launch control, quick-shift optimization, and a pit-lane limiter—all adjustable while riding.

After fitting the Rapid Bike Racing2 kit on my 2024 KOVE 800X Pro, I was genuinely blown away by just how sharp and adaptable the bike feels now. The kit arrived with a compact Racing2–specific ECU, plug-and-play waterproof wiring, and clear, illustrated installation instructions—installation was smooth and stress-free.
Once everything was hooked up, the real fun began. The new app-driven tuning lets me choose from three modes—Eco, Touring, and Sport—each with 20 levels of intensity. Whether I’m rolling easy on long rides, cruising through city traffic, or chasing dirt trails, dialing in the perfect throttle feel takes just a few taps on my phone.
What really sets this kit apart, though, is the auto-adaptive mapping powered by the stock O₂ sensor signals. The ECU intelligently adjusts the fuel injection map on the fly—two O₂ sensors allow per-cylinder tuning, smoothing out throttle response and enhancing power delivery across the entire range.
Beyond improved fueling, the Racing2 opens up a suite of advanced features—spark advance optimization, engine-brake management for smoother deceleration, and extended injector flow across RPM ranges. And if you add the optional YouTune accessory, you unlock traction control, launch control, a pit-lane limiter, and real-time parameter tuning right from the handlebars.
There’s also a handy diagnostic tool baked into the system—it can read and clear stock ECU fault codes, which came in clutch when I was ensuring everything was working right.

I recently fitted the Rapid Bike Racing2 kit onto my 2025 Kove 800 X Pro, and holy smokes—it feels worlds better. The compact ECU and sleek plug-and-play harness made installation surprisingly straightforward. The kit’s smaller size and lighter weight, combined with its faster microprocessor, are immediately noticeable upgrades from previous versions.
Jumping into the smartphone app is where things get really fun. You get three riding modes—Eco, Touring, and Sport—each with 20 adjustable intensity levels. Whether I’m saving fuel on long rides or dialing up throttle response for technical single-track, tweaking my ride setting takes just a few taps.
What truly blew me away, though, is the auto-adaptive fuel mapping. The Racing2 dynamically adjusts the fuel injection on the fly by smartly modulating signals from both Narrow‑Band and Wide‑Band lambda sensors. This not only smooths out throttle response but also adapts to changing weather and altitude—especially noticeable in the lower to mid RPM range where hesitation used to crop up.
It also comes with a handy diagnostic feature—no more guessing when the stock ECU throws codes. Plus, the Racing2 unlocks advanced features like support for an optional electronic shifter, multiple map presets, RPM shifting up to +1000 rpm, and even the ability to remove the speed limiter. And if your bike has twin lambda sensors (like mine), the kit can auto-correct each cylinder individually.
For riders who want even more real-time control, pairing the Racing2 with a YouTune controller is a game-changer. You can tweak engine braking, refine shift-cut timing, manage speed limiter behavior, and view engine parameters live while riding.

I just finished installing the Rapid Bike Racing2 kit on my 2024 Kove 800 X Pro, and the transformation is wild—in the best way. The app-controlled tuning with three riding modes—Eco, Touring, and Sport—each offering 20 intensity levels, gives me instant control over the bike’s character. Whether I’m easing through dirt paths or hammering on gravel, dialing the ride mode takes just seconds and feels intuitive.
Installation was seamless—plug-and-play wiring, compact unit, practically clause-free setup. The streamlined design and lightweight build of the Racing2 feels visibly more polished than older models. The kit also includes a diagnostic function, which came in handy during the setup to check for any ECU quirks.
The difference in throttle response is noticeable. The Racing2 uses real-time feedback to keep fuel mapping adaptive and precise. The bike's mid-range is suddenly alive—strong but smooth, with zero hesitation when pushing back on the throttle. It now feels like the bike is smart enough to anticipate what I want next.
What really impressed me was how this intelligence pairs with the lightweight Kove chassis. With its 799 cc parallel twin delivering 95 hp and a dry weight hovering under 370 lbs, this bike already had a hooligan streak built-in. Slap on the Racing2, and it’s like giving that hooligan a PhD in ride control.
