(2026) BMW M1000RR (K66) Stage 1+ Performance Calibration With Handheld Tuner

CURRENTLY PENDING CARB APPROVAL

MAKE SURE TO REVIEW THE TABS ABOVE: HANDHELD, DYNO RESULTS, RESOURCES AND MORE INFO!

The halo bike of BMW, the 2026 BMW M1000RR, is the most potent offering for the street that BMW has ever offered to the public! While the 2026 looks almost the same, it's what's under those fairings that has REALLY changed. We have more compression, redesigned head, new airbox and inlet design, a 58* throttle (vs 72* for 2024), and let's not forget about its new software. BMW is already claiming 6hp more for 26 over the 24 model, though the models that are rolling out are still HEAVILY restricted, and that's where we come in! Stage 1 was developed to remove these restrictions and unlock your M1000RR’s full potential, the difference on the 2026 with our flash is the most astonishing out of any BMW to date - a must have.

THE BT MOTO DIFFERENCE

We are obsessed with BMW motorcycles and it shows. Racers at the circuit tracks, the drag strips or even a commuter will appreciate the changes our Stage 1 tune brings. Thoroughly tested in all aspects by track racers, drag racers or just the casual street rider wanting a more exciting bike to ride, our Stage 1 makes the bike how it should have came from the factory, and then some. We purchase the motorcycles and fully disassemble, diagnosis, datalog, and test for every aspect of performance and rideability while keeping fuel economy, emissions, and engine reliability at stock or better levels! Our growing YouTube Channel has highlighted a lot of these changes! We have kept these bikes in our personal fleet since 2010, innovating new features and working on feature requests along the way. Our customers benefit from this process tremendously as things that bother the them get brought to the forefront and fixed, making a more enjoyable riding experience. No one has more thorough research, into making these bikes more enjoyable than us, with a money back guarantee. Be sure to reference our in-house YouTube reviews and testing for before and after horsepower on California 91 octane, before and after acceleration testing and rideability quirk fixes that we complete with a third party on all bikes. As a final point, we send out all our calibrations to be tested by CARB for government emissions compliance and third party verification, before and after horsepower, along with tailpipe emissions to get a certified EO number to be sold in California - 50 state legal - as the California year round riding and bike market is huge!

DRAG / ROLL RACERS / AND MAX SAFE ENGINE HORSEPOWER

Drag racers have the capability to ride derestricted, TC refined, and torque management maximized, allowing you to put the power down, gear after gear without limitations. Because of our extensive factory ECU understanding and 100's of engine channels we've datalogged, we are able to adjust the motor far better then the competition who simply flatten fuel and advance ignition blindly like in the 1990's. We are uniquely setup to use the tools granted to us with the factory ECU to activate custom code like full-time closed loop, which utilizes factory sensors to "auto tune" the motorcycle at every throttle position without custom dyno mapping needed, adjust SOI (injector phase), rewrite spark maps per octane and address hidden torque maps to make sure the engine never holds back horsepower while not putting the bike outside its safety window. We also address additional safety functions to keep the engine reliable in extreme environments beyond factory tolerances. We test best and worst possible fuels and optimize all of them to the best of our abilities. Years of experience have helped us squeeze every bit of power from the bike, while keeping it reliable and consistent. Be careful with others claiming more power as there is a delicate balance. Forced ignition advance, deleted knock control, and lean air fuels are a short way to an expensive repair for 2HP gains.

TRACK RACERS

Track racers can enjoy modified TC (traction control) settings, wheelie management, adjustments for different tire sizes, smoother throttle transitions/tip-in, consistent and predicable power, and specialized tuning for specific tire sizes. All this comes together to make sure you start and finish a turn to the best of the bikes capability. Working directly with MotoAmerica racers and regularly datalogging all of the fastest stock ECU BMW S1000RR riders has opened a window and drastically improved our mapping and knowledge-base to better help our customers perform properly on the track keeping you ahead of the pack.

STREET RIDERS

For the casual rider, derestricting the bike is the biggest advantage of our tuning. This makes the bike a blast to ride and gives the rider smile inducing power from one simple modification. Making sure the throttle is smooth when cruising and power brutal when you need it is important for all liter bike owners. Stop and go traffic or canyon carvings on the weekends is where we put our development bikes to the test as they need to ride in low speed situations as good as they work on the airstrip at wide open throttle. Hundreds of hours and miles go into our tuning and testing, among several bikes, fuels, and test riders before we ever release our product. We want to present the best product on the market while leading the pack in customer satisfaction. 

No one tests like we do!

WHAT'S INCLUDED IN STAGE 1?

• De-restricted Throttle +50hp gains in the midrange, and +10-20whp over the curve!
• De-restricted Exhaust Valve and intake flappers, open to 100% in certain riding scenarios for best sound and performance
• Throttle response increased 12% in every race pro 1-3 mode to reach a target of 100% throttle. Road mode de-sensitized for highway cruise, though the stock offering is normally jerky
• Cruise control jerkiness adjusted for highway cruising tip in and out
• Worse then the S1000RR restriction! The M1000RR has a top end Torque limiter of 74% raised now to 100% free top end horsepower, over 200whp on a stock bike. (a BT Moto exclusive!) 170mph limiter (due to torque limit) removed will go 188mph GPS on stock sprockets. 
• Better Fueling, cleaned up for maximum fueling economy and horsepower gains
• Second and third gear transmission limiter removed
  
• Enhanced and restructured hard cut rev-limiter
• Mapping available for different modification combos
• Heat Management through better fueling, and lower cooling fan strategy
• Over a second off your 60-130mph times!
• Please note: Our stage 1 tuning is certified 50 state legal by CARB EO D-868. As of July 2025, we no longer offer extended rev limiter options on stage 1 tuning. Stage 1 is designed to for OEM dealer level serviceability and to abide by BMW's warranty standards. For race use please consider our stage 2 mapping upgrade.

HOW DO WE ACCOMPLISH THIS WITH STAGE 1?

• THROTTLE RESTRICTION / TORQUE / GEAR LIMITATIONS - Giving you the ability to utilize 100% of the throttle is paramount in track situations where you need all the power you can get on demand. The factory file has "dead spots" that may cause the M1000RR to behave in an unpredictable manner when corner exiting. This also means any kind of straight line acceleration also suffers. We remove these factory restrictions to ensure a smooth and predicable throttle, all the way to redline. It's like getting a new engine, all over again! Only BT Moto has figured out how to "fully" de-restrict the 2026, through torque limits to achieve max power and 100%.  The competition still is getting limited. With the torque limiter in place the bike is slower then the 2010 BMW S1000RR!
• EXHAUST VALVE / INTAKE FLAP - The exhaust valve is a double edged sword. It does good by making back pressure when needed but also hinders the 2025 M1000RR from making the most power possible at mid to upper RPM ranges. The valve closed makes the bike a lot more quiet than if it were open, even slip-on exhaust sounds almost the same as stock due to this valve closing so much. Opening this valve for racing use allows for some horsepower gains, as they are gear and RPM dependent, just like the butterfly valves for the throttle. Lower gears have a smaller valve opening which will reduce overall volume and power by 3-5HP, even in lower RPM’s. Our mapping still utilizes the stock exhaust valve to give you maximum power but also opens it up when you need it most.
• FUELING - The 2025 BMW M1000RR fueling is rich for worldwide environment (desert) and longevity purposes but it's overkill. It is also set artificially lean at idle, cruise, and warm up, which results in stalling and cold/hot start issues. The new M1000RR is factory equipped with 5-wire widebands (just like the 2020+ S1000RR) and is very precise on targeting a specific AFR (Air/Fuel Ratio) through a closed loop corrective system from idle to redline. Being factory rich also helps it cool the turtleshell exhaust system. However, fuel can be trimmed for better result as it targets real time fuel corrections.
• HEAT MANAGEMENT - Lets face it, this bike rides a little on the hot side. Due to the new exhaust system and idle/cruise AFR mixtures the bike is a recipe to being constantly in the 215+F range and burning your legs while you ride, making it uncomfortable anywhere you’re not going 50+MPH. We have solved this issue by adding our low fan temp modification to this flash as a standard baseline feature along with different cruise mapping which has curbed temps extensively.
