2025 Honda CBR1000RR-R SP Review: BT Moto Tuning & Velocity Stacks

Comprehensive Review of 2025 Honda CBR1000RR-R Dyno and BT Moto Tuning with Velocity Stacks

If you want to buy the most powerful Honda CBR bike, the 2025 Honda CBR1000RR-R SP is staring at you with a fierce, unapologetic glare, ready to dominate the asphalt. This beast isn't just a bike—it's a statement. Its aggressive, racy DNA comes alive in the diamond-style aluminum main frame, a masterpiece of engineering that shaves every unnecessary gram. Also, at just 445 pounds, it’s one of the lightest and most agile liter-class machines ever built. With a perfectly tuned 53:47 weight distribution, it delivers a high center of gravity that translates into mind-blowing flickability and razor-sharp handling.

And to unleash every ounce of power from this monster, we at BT Moto know exactly how to push the 2025 Honda CBR1000RR-R SP to its absolute limits. How? With BT Moto Tuning—the ultimate upgrade for your beast. Oh, and we didn’t stop there. We’ve achieved the world’s first tested velocity stacks for the 2025 Honda CBR1000RR-R SP! 

In this comprehensive 2025 CBR1000RR-R SP review, we’re diving deep into the performance magic: how our BT Moto flash tuning combined with velocity stacks delivered some INSANE, jaw-dropping numbers. 

Let’s fire it up and get started.

First Up, Stock Dyno Testing

We’ve got our hands on the latest and greatest from Honda—the 2025 CBR1000RR-R SP, and we couldn’t wait to put it through its paces. From the moment we laid eyes on it, we were electrified by its stunning design and the upgrades Honda’s packed into this machine. With a completely stock exhaust system, the bike already impresses, but what’s really exciting is what’s under the hood. They've bumped up the compression from 13.4 to 13.6, reworked the motor, and made significant updates with new lightweight valves, valve springs, DLC-coated cam lobes, a new gear ratio, and a revised ECU. Honda's done a lot to make this model harder to tune and derestrict, but if you know us at BT Moto, you know nothing is going to stop us from unlocking its full potential. 

On the dyno, we put the stock tuning to the test—and the results were nothing short of impressive. The 2025 CBR1000RR-R SP delivered a solid 179 wheel horsepower, which is a significant jump over the 2021 model. Check out the comparison image below showing the difference between the stock 2021 (blue) and 2025 (red) models (both with stock ECU tuning).

It’s crucial to remember that the 2021 model of the CBR1000RR-R SP was heavily restricted from the factory. Honda had intentionally dialed back the performance to meet regulatory standards, which ultimately left a lot of untapped potential under the surface. This is exactly where the 2025 model shines, as Honda has clearly addressed many of those restrictions, allowing the bike to breathe easier and deliver a more seamless performance experience right off the bat. But let’s be honest—Honda’s factory tuning was only just scratching the surface of what this beast is capable of.

BT Moto Flash Dyno Testing Results

Once we got our hands on the mod file and flashed it into the bike, the transformation was immediate and unmistakable. The results? Well, let's just say we weren’t exactly shocked. With the BT Moto Flash and our custom tune, we unlocked a monstrous increase of almost 20 wheel horsepower at the top end. That’s right—straight from a solid 179 stock wheel horsepower to an astounding 196 wheel horsepower. The power is now absolutely intoxicating, with a level of performance that takes the 2025 CBR1000RR-R SP to a whole new stratosphere.

BT Moto Velocity Stack Installation and Dyno Testing

With the new airbox and velocity stacks introduced on the 2025 Honda CBR1000RR-R SP, we knew right away that we’d have to adapt our approach. The stock stacks were no longer going to cut it, and we were eager to see how our custom-designed BT Moto velocity stacks would compare. But this wasn’t just about swapping out the stacks—we had to ensure that the entire air intake system was optimized for maximum performance.

Given that the new stacks required a different air filter setup, we didn’t hesitate to upgrade to the Sprint air filter, a high-performance option that allows significantly more air to flow through compared to the restrictive stock paper filter. With that installed, we moved on to fitting our BT Moto velocity stacks 1-on-1, which we had to custom fabricate to perfectly fit the redesigned airbox. It wasn’t a simple job, but the results were absolutely worth it.

With everything in place, it was time for the real test: putting the bike on the dyno to see how the combination of our BT Moto Flash and custom velocity stacks would perform.

And just as we’d hoped, the gains were substantial. The prototype stacks immediately showed their value, pushing the bike’s performance to the next level. We saw an impressive 16 wheel horsepower gain right at the top end. But it didn’t stop there. Dyno testing also revealed a consistent peak-to-peak increase of 5 horsepower, a solid result that’s a clear indicator of how well these velocity stacks work.

What’s even better? We didn’t lose any bottom-end performance, which is often where bikes tend to suffer when you install aftermarket stacks or tune for peak power. Instead of shifting the power curve in a way that sacrifices lower-end torque, our velocity stacks provided a clean, smooth increase up top without compromising any of the usable power down below.

In the end, the performance boost was everything we expected and more. This was a perfect example of how carefully engineered upgrades—like our BT Moto velocity stacks and Sprint air filter—can unlock massive gains without sacrificing the overall rideability of the bike.

Next up, we had to try it with VP racing fuel to see the difference in numbers.

BT Moto Flash with Velocity Stacks and VP Fuel

What do you know? The numbers shot through the roof. We were now looking at an incredible 210 rear-wheel horsepower—a massive jump from where we started. This is the kind of power that doesn’t just feel fast, it feels unstoppable. The combination of VP Racing Fuel, our velocity stacks, the Sprint air filter, and the BT Moto tuning unlocked a whole new level of performance that proves just how much potential this bike has when everything is dialed in perfectly. 

This is exactly why we do what we do—because the results speak for themselves. Pure, unadulterated power. 

And there you have it—proof that the difference BT Moto flash tuning and velocity stacks can make is nothing short of insane. The gains we’ve unlocked are a testament to the power of precision tuning and carefully engineered upgrades. If you want to experience the same heart-pounding thrills that we just unleashed on the 2025 CBR1000RR-R SP, you can get in on the action with our BT Moto Flash tuning. 

Most importantly, you don’t even need to leave your garage. At-home flash tuning for the 2025 CBR1000RR-R is now available, so you can bring the race-level performance straight to your bike without the hassle. Get ready to experience what true power feels like—because once you’ve felt it, there’s no going back.
