BMW F 750 GS BT Moto ECU Flash Review with Dyno

The BMW F 750 GS is a superb motorcycle acclaimed for its versatility, good handling, and comfortable ride. Priced significantly lower than the flagship R1250GS, the F 750 GS offers an accessible alternative for enthusiasts who aspire to own the 1300 or 1250 models but are constrained by budget. With the BMW F 750 GS price under $10,000, it provides an impressive ride quality and is notably user-friendly.

In this comprehensive BMW F 750 GS review, we will discuss the 2023 model equipped with BT Moto ECU Flashing, providing before and after comparisons, dyno testing, and more. It’s worth noting that the 2023 BMW F 750 GS model will not be featured in the 2025 lineup, which will only include the F 800 and F 900 models. However, the information we cover today will also be relevant to those future models. Let's begin.

BMW F 750 GS Stock Impressions and Top End Testing

To start off, here’s a fun fact: Both the BMW F 750 GS and the 850 model were available in 2023, and they actually use the same 853cc engine. But here’s the twist: even though they have the same engine, their power outputs are different. Why? Because BMW tweaks the F 750 GS to offer less power—basically, they limit it through the bike’s software to encourage buyers to spend a bit more for the 850. This is where BT Moto steps in. They can tweak the software of the F 750 GS to unlock more power, essentially giving it a boost that makes it as powerful as, or even more powerful than, the 850.

Overall, riding the F 750 GS is a real pleasure. It’s got a great mix of power and agility, making it perfect for different kinds of rides. It’s also built for comfort, especially on long trips. The seat is 32 inches off the ground, which is great if you’re not too tall. Plus, it comes with a cool 6.5-inch TFT display, just like the one on the 2019 XR model that’s been a hit in the US. Nevertheless, with 77 horsepower, we clearly felt that this bike is definitely underpowered. And when given 100 percent throttle, the bike gives about 40 percent - something that our flashing could fix easily. 

For the top-end testing, we pushed this bike to its limits—and it didn’t take long to notice something was off. The bike felt sluggish, almost as if only the first 50% of the throttle was doing anything, while the rest felt empty and unresponsive. On top of that, the gear shifts weren’t smooth, which made the bike feel unbalanced, especially around corners. You could say the BMW F 750 GS is fun up to the mid-range, but beyond that, it loses its spark.

That said, the brakes were solid, thanks to the reliable Brembo anchors on this machine. We really pushed the bike to the max, as you can see in the image below. But there was a massive restriction stopping us from achieving the best out of it. 

To get a better sense of the bike’s performance, we ran a stock 20-100 MPH GPS test. It took us 9.69 seconds, which is actually pretty impressive considering the price of the 2023 BMW F 750 GS. The bike feels stable and well-planted, which is a big plus.

However, the clunky up and downshifts were a bit annoying, and we noticed a strange flat spot in the power above 5,000 RPM, which took away some of the fun at higher revs. But that got us more excited since we knew about a reliable solution.

Dyno Testing, Stock vs. BT Moto Flash

On the dyno, we got the real numbers after the ECU flashing. In the image below, you can see the stock performance in blue and the BT Moto flash results in red. Right away, you’ll notice that the flash added a massive 25 wheel horsepower at peak RPM. Even when comparing the peak-to-peak numbers across the entire RPM range, there’s a consistent 20 wheel horsepower gain.

With the stock setup, the bike operates at about 40% throttle. The BT Moto Flash removed this restriction, unlocking the extra power that was hidden. Additionally, there was a significant torque boost, going from 39 wheel torque to an impressive 53 wheel torque.

The flash didn’t just boost power and torque—it also improved several other aspects of the bike. It lowered engine fan temperatures, enhanced throttle response, enabled full-time closed-loop operation, refined the startup process, and more.

BMW F 750 GS BT Moto Tuning Impressions and Top End Testing

Well, well, well. After the ECU flash, we took the bike out for a 50-mile ride, and the difference was night and day. It felt like a completely new machine, with the top-end speed climbing effortlessly. In many cases, we saw gains of over 20 wheel horsepower in the RPM range above 5,000 RPM. Honestly, the results were incredible for such a simple ECU flash.

The downshifting also became noticeably smoother. While upshifting was pretty clunky before, it improved significantly (though we have to admit, there’s still a bit of clunkiness). Even so, the improvement in upshifting was a game-changer compared to how it was before.

Next up, we put the top-end performance to the test—and wow, what a difference! The power was instantly noticeable, and the transformation was nothing short of incredible. The bike finally felt alive, as if it had been holding back all this time and was now unleashed to its full potential. It pulled hard and smooth, climbing through the gears effortlessly and delivering an adrenaline-packed performance. The way it transitioned into beast mode was seamless, giving us the kind of top-end power we’d been craving all along. It truly felt like a completely different motorcycle.

As you probably guessed, the next step was the BT Moto 20-100 MPH test to measure the performance gains—and the results were absolutely mind-blowing. The flashed BMW F 750 GS was an impressive 1.6 seconds faster than the stock version. Just think about that for a moment—1.6 seconds is a huge difference in this range, showing just how much power and efficiency the flash unlocked. It performed exactly as we had hoped, if not better.

THE BOTTOM LINE

And there you have it. After riding 100 miles stock and 100 miles flashed, we’ve used the most comprehensive R&D in the aftermarket tuning industry to completely transform the 2023 BMW F 750 GS. This extensive testing gave us a clear understanding of what the bike needs to deliver a better and more enjoyable experience for the rider. Most importantly, it ensures the tuning process remains safe for our customers.

By the way, even if you’re not chasing the unrestricted power the flash unlocks, there’s plenty of reason to consider it. The smoother throttle response and significantly less clunky shifter are game-changers on their own. Plus, our flash enables full-time closed-loop operation, meaning the bike is essentially fine-tuning itself as you ride for optimal performance.
