I recently installed the Rapid Bike Smart2 Tuning Kit on my Honda CB 1000R (2021–2025), and the experience has been outstanding from start to finish.

The compact dimensions led to an impressively tidy installation—no bulky hardware cluttering my setup, just a sleek, efficient fit. I particularly appreciated the plug‑and‑play wiring harness being separate from the main module, which made routing wires clean and stress-free
Pairing via Bluetooth with the free software was slick and intuitive—no messy wires, just seamless, wireless control over the tuning process
What truly sets this kit apart is its clever design for reversibility. You can switch back to the stock configuration with two simple steps: performing a throttle-opening sequence or toggling a digital switch within the software—both work instantly and flawlessly.
The integrated status LED is such a practical touch—instantly tells you the module’s status, a great confidence-booster before hitting the road
Performance-wise, this kit delivers noticeable enhancements. By intelligently modulating the lambda (O₂) sensor’s signal, the stock ECU is prompted to adopt a richer air/fuel ratio across the rev range—all while preserving its self-adaptive logic. The result? Smoother power delivery, crisper throttle response, and a tangible bump in torque, with performance gains that feel consistent with the engine’s stock character
My aftermarket exhaust now performs and responds even better, thanks to that optimized fueling
A quick heads-up for riders in emissions-conscious regions like California: this kit is not CARB- or EPA-approved for street use and is intended for closed-course or track-only applications, so always check local regulations before installing

I recently installed the Rapid Bike Smart2 Tuning Kit on my Honda CB 1000R (2021–2025), and the difference has been palpable.

First off, the compact size makes installation remarkably neat—no bulky bits digging into my wiring. The separate plug-and-play wiring harness keeps everything tidy and easy to manage
Pairing it via Bluetooth with the free app was smooth and hassle-free—no wires, just intuitive tuning control at my fingertips
One feature I truly appreciate: two quick ways to revert to stock settings. I can either do a simple throttle‑opening sequence on the bike, or toggle a switch in the app—it’s seamless
The added status LED is a welcome bonus—instant diagnostic feedback before hitting the road or track
Performance-wise, the kit intelligently modulates the lambda sensor signal, coaxing the stock ECU to run a richer air/fuel mixture across the whole rev range. The result? Noticeably smoother power delivery, snappier throttle response, and a significant torque uptick—all without messing with the ECU’s self-adaptive behavior
My aftermarket exhaust sounds better too—seems to benefit directly from that optimized fueling
A quick heads-up for riders in regulated regions like California: this kit isn’t CARB- or EPA-approved for street use—it’s designed for closed-course or track-only use. Always check your local emission laws before installing

I recently installed the Rapid Bike Smart2 Tuning Kit on my Honda CB 1000R (2021–2025), and it has transformed the ride in the best possible way.

Installation was a breeze—the module is compact, and the plug-and-play wiring harness keeps everything clean and hassle-free. The standalone harness is a nice quality touch that made installation feel professional and tidy.
Bluetooth integration is slick, as promised. I paired it with the free software and was able to manage tuning adjustments wirelessly—no tangled cords, just straightforward, intuitive control
One of my favorite features: two easy ways to revert to stock tuning. Whether you're flipping a throttle-opening sequence or using the digital switch in the app—it's instant and seamless.
The integrated status LED is also a thoughtful add-on—great for quick diagnostics before heading out.
On the performance side, this kit genuinely enhances the experience. By cleverly modulating the lambda sensor signal, the Smart2 kit prompts the stock ECU to adopt a richer air/fuel mixture across the powerband. The result? Smoother overall power delivery, sharper throttle response, and a noticeable torque boost, all while preserving the ECU’s self-adaptive logic.
Plus, my aftermarket exhaust sounds and performs better—you can tell it’s benefitting from the richer fuel mix.
Heads-up for compliance-conscious riders: If you're in places like California, be aware that this product is not CARB- or EPA-approved for street use and is intended for closed-course or race-track use only. Always check your local emission laws before installing.

I recently fitted the Rapid Bike Smart2 Tuning Kit (Honda CB 1000R 2021–2025), and it’s hands-down one of the most intuitive and effective performance upgrades I’ve installed.

From the start, I appreciated how compact the unit is, making installation neat and stress-free. The plug‑and‑play wiring harness is cleverly separated from the main module, keeping wires tidy and clean under the tank
Pairing via Bluetooth with the free app was seamless—no tangled cables, just instant connectivity and intuitive control
My favorite feature? The effortless way to switch back to stock mode. With either a quick throttle-opening sequence or the digital toggle in the app, I can revert instantly—perfect for track days or street cruising
Plus, the status LED on the module gives me fast diagnostic feedback—great peace of mind before pushing the bike hard
On the performance front, the Smart2 kit works wonders. By subtly modulating the lambda (O₂) sensor signal, it prompts the stock ECU to run a richer air/fuel mixture across the rev range while maintaining smooth, self-adapting power delivery
The result? Sharper throttle response, smoother midrange torque, and better synergy with my aftermarket exhaust—without messing with the ECU’s logic
A word of caution: If you're in a jurisdiction with tight emissions rules—like California—this kit may be intended for closed-course or race-track use only, since it's not CARB- or EPA-approved for street riding
