THIS PRODUCT IS 50-STATE LEGAL (C.A.R.B. EO# D-868-22)

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

The 21-22 BMW M1000RR is one of the best motorcycles on the market! While the bike is incredible all around, the US and European model M1000RRs have been restricted from the factory, not allowing you to unleash the full potential right off the dealer lot. The US models have worse restrictions than their European counterparts, but either will benefit tremendously from our Stage 1 ECU calibration. Our Stage 1 mapping was developed to remove these restrictions and unlock your BMW M1000RR’s full potential . The post-tuning changes on the 21-22 BMW M1000RR are the most astonishing out of any BMW to date - a must-have modification to an otherwise perfect motorcycle.

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 come from the factory, and then some. We purchase the motorcycles and fully disassemble, diagnose, datalog and test for every aspect of increased performance and drivability 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. The customer benefits from this process tremendously as things that bother the customer get brought to the forefront and fixed, making for 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 horrible California 91 octane, before and after acceleration testing, and drivability quirks fixes that we complete with a third party on all bikes.

As a final sticking point, we send out all our calibrations to be tested by CARB for government emissions compliance and third-party verification of before and after horsepower, along with tailpipe emissions to get a certified EO number to be sold in California, a 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 all the capability to de-restrict throttle, traction, and torque management to put all the power to the ground while managing wheel up behavior, 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 than the competition, who simply flatten fuel and advance ignition spark 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 , 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 it outside its safety window. We also address additional safety functions to keep the engine alive in extreme environments beyond factory tolerances.

We test the 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 quick 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, and consistent and predictable power. All this comes together to make sure you start and finish a turn to the best of the bike's capability. Working directly with MotoAmerica racers and regularly datalogging all of the fastest stock ECU BMW M1000RR 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, de-restricting 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 simple modifications. Making sure the throttle is smooth when cruising and power brutal when you need it to be 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 +60HP gains in the midrange (lower gears), and +10WHP over the curve!
• De-restricted Exhaust Valve, open to 100% in certain riding scenarios for best sound and performance - no exhaust needed.
• Throttle response increased 12% in every race pro 1-3 mode to reach a target of 100% throttle. Road mode desensitized for highway cruising, normally jerky and twitchy.
• Cruise control jerkiness adjusted for highway cruising tip in and out.
  
• Revised fueling part to full throttle for maximum economy, throttle response, and performance targets utilizing 100 channel datalogging.
• Second and third gear transmission limiter removed for full wheelie control and roll race hole shot hit (BT Moto exclusive).
  
• Enhanced and restructured hard cut rev-limiter for less drama at the bikes limit.
• Top speed limiter removed (dash still stops at 192MPH for now but can GPS verify faster).
• Mapping available for all popular modification combinations.
• Heat Management through better fueling, and lower cooling fan strategy.
• A second off your 60-130MPH time!
• BMW "LOUD" STARTUP/SERVO IS LEFT INTACT ON STAGE 1
• 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?

The purpose of this modification is to get a optimized factory like bike at its power capabilities with or without hard parts all while maintaining factory reliability and emissions standards if applicable to your state or country.

• THROTTLE RESTRICTION / TORQUE / GEAR LIMITATIONS - We give you the ability to utilize 100% of the throttle , which is paramount in track or racing situations where you need all the power you can get on demand. The factory file has "dead spots" that may cause the BMW M1000RR to behave in an unpredictable manner when exiting corners or hitting the throttle from a roll. This also means any kind of straight line acceleration suffers, especially in high RPM's. Gain 60hp in 2nd and 3rd gear , and 15hp in others ! Incredible. We remove these factory restrictions to ensure a smooth and predictable throttle, all the way to redline, it's like getting a new engine, all over again!
  
• EXHAUST VALVE / INTAKE FLAP - The exhaust valve is a double-edged sword . It does well by making back pressure when needed, but also hinders the 2021+ BMW M1000RR from making the most power possible at mid to upper RPM ranges. The valve closed makes the bike a lot quieter 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 RPMs. Our mapping still utilizes the stock exhaust valve to give you maximum power , but it also opens it up when you need it most. The intake valve is closed at certain RPM's from the factory. We open this fully to allow max airflow to the airbox at all times.
• FUELING - The 2021+ BMW M1000RR fueling is rich for worldwide environment (desert) and longevity purposes, but we've found that 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 BMW M1000RR is factory equipped with 5-wire widebands (just like the 2020+ S1000RR) and is very precise in 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" system for the longest life and warranty-free life. However, fuel can be trimmed safely for better results as it targets real-time fuel corrections.
• IGNITION - On the 2021+, we adjust per cylinder corrections for maximum engine performance and increased torque and horsepower via steady state dyno tuning and datalogging verification for all fuels . We also keep safety maps active in case of poor fuel. We do not overwork these engines blindly, as they do not respond well or make power from excessive ignition. What this means for the end user is automatic power increases with higher octane fuel in the bike, without changing the map.
• HEAT MANAGEMENT - Let's 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 for 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.

REVIEW VIDEO

​ HOW THESE POWER GAINS ARE POSSIBLE

For those who don't really understand how we get so much power from a simple ECU flash , it's really quite simple. From the factory, the M1000RR is SEVERELY restricted. These restrictions are software-based and can be removed with our flash. How bad are the factory restrictions? See the graph below. The numbers represent a maximum % of throttle allowed by the ECU based on the rider commanding 100% throttle twist . You can see some portions are down to 35%! We simply fix this to command a full de-restriction so you can get all your power back.

Don't be fooled by imitations with empty promises, see why everyone uses us:
