Product Description



With the success and amazing feedback we’ve gotten from our M/S 1000RR/R/XR flashes, we wanted to turn our focus to getting into your engine in a more efficient way. Our custom velocity stacks and revised tuning for the OEM widebands not only gives a dramatic, top-end power increase, but also doesn’t loose any power in the low or midrange of the RPM. Our easy to install, custom velocity stacks don’t shift the powerband over and decrease power down low. We managed to make more power where it matters.

We found with competitor velocity stacks that a “one size fits all” approach doesn’t work for the M1000RR and S1000RR airboxes. As we have exhaustively tested this in box airboxes and found dramatic power loss. Instead, we we spent months testing and developed two different stack designs. One for the M1000RR and one for the S1000RR that make the best power for each. (dyno results below). With our FTCL (full-time closed loop) tuning there’s no need to worry about your bike going to lean or rich. Your bike tunes itself (BT Moto exclusive feature).

We are confident our velocity stacks will be a noticeable and quantifiable change in your bike that leaves you smiling every time you get off the seat.

BT Moto velocity stacks are developed and designed TO WORK WITH BT MOTO CUSTOM FLAHING. Flash adjustments include revised funnel actuation and fine tuning for BT Moto custom velocity stacks. *VELOCITY STACKS DO NOT REQUIRE FLASH PURCHASE BUT IS RECOMMENEDED FOR ADVERTISED RESULTS*



  • BT Moto velocity stack kit (install video below).
  • FTCL (full-time closed loop) lambda targeting enabled for all applicable models (comes with flash).
  • Correct fueling on both banks in “Alpha N” mode and race modes (comes with flash).
  • Funnel actuation corrected for BT Moto velocity stacks (comes with flash).
  • Custom velocity stack designed for YOUR airbox. No one size fits all approach.
  • OEM fitment and ability to go back to stock when ever you’d like.
  • Plug and play
  • Gain 5-10HP (depending on bike and mods) at higher RPM’s (with BT Moto Flash).
  • No power loss in low or midrange (with BT Moto Flash).


3D printed from lightweight composite, the BT Moto Velocity Stacks have been carefully engineered and designed to maximize power in the higher RPM range while not losing power in the low RPM range.

Made for an OEM fit, the BT Moto velocity stacks aluminum ring clamp to ensure tight fitment while also being easy to install. These are plug-and-play and require no additional modifications to your airbox to fit. Simply remove your factory velocity stacks and install ours in. Coupled with our custom flash, the combination makes an extremely easy install and tune that can be done in your own garage with basic tools or mechanical knowledge.

Dyno Testing

Below is our custom flash with BT Moto velocity stacks versus stock and Stage 2 with no stacks. You can see little to no loss in the mid and low-range RPM. Up top you can see a significant gain. All on pump gas 93. Same day testing on the same bike. All models M100RR and S1000RR models make different power numbers than S1000R and S1000XR models but the percentage of power added from velocity stacks remains the same.

RED LINE – Factory Tuning, 93 Pump Gas, Bolt-Ons

**All in-house testing performed with 93 octane pump gas, unless otherwise stipulated. Different modifications and dynometers may make different power. Usage of a lower octane will yield smaller power gains. All power is measured from the wheel and not the crankshaft, whp (wheel horsepower) and wtq (wheel torque)**


Difficulty: Easy with basic mechanical knowledge and tools

  • “ Bike is running awesome and no out of the ordinary popping under load during downshifts at high rpm. My hats off to your team for making me feel like I have a personal tuner at my disposal. Really appreciate the quick turnaround to get me straight. I can definitely feel the extra power! ”

    Andy Young - Maryland Aug 28, 2018
  • “ This product is amazing.  I feel like I have a better version of my bike.  Like it should have come this way.  The throttle smoothness and even power band make it a joy to ride.  I no longer feel as if I'm riding a wild bronco lol. Thank you again, I didn't think that a L-twin could behave this well.  Also, your customer service is the best.  I could always reach you by email or phone.  I will tell everyone I know about this fantastic addition.  Keep up the great work, guys! ”

  • “ I have a 2015 S1000RR and was extremely skeptical when I heard about BT Moto and the power they got out of an ECU flash.  After speaking with the team at BrenTuning, all my hesitations were put to rest and I haven't stop winning first place trophies since! BELIEVE THE HYPE! ”

  • “ Bren and his team did an awesome job on my bmw s1000rr. Went from 179rwhp an 83 rwtq to 206 rwhp and 93rwtq. Customer service was great and I highly recommend them for any of y'all that want to make that power!! ”

  • “ Purchased the tune for my 2015 BMW S1000RR. Was skeptical at first and initially had a bunch of questions. Chris was very patient with me and answered them all. Had some problems after receiving my ecu back and Chris was very helpful in getting all my issues worked out. Bike runs fantastic. Definitely worth it. Thank you again guys for dealing with my questions and taking care of everything before and after the purchase. Fantastic customer service. ”

  • “ After doing some research it was obvious that BT Moto was the best option for tuning of my S1000RR. I wont go into details but after multiple overnighting of parts to me at no additional charge, I'm really impressed and satisfied with the end result and I haven't even tried out my race fuel tune yet! To top if off I received a random care package of goodies from Chris today. The customer service at BT Moto is probably the best I've received from any business I've dealt with. Their email response times are unreal as well, lol. Literally sometimes instantly, kinda weird. lol. I would recommend any and everyone to BT Moto for your S1000RR tuning solution. If anyone has any questions or are hesitant before purchasing, feel free to shoot me a message and I'll help / assist / give you a more detailed opinion on my experience as well. ”

    Trey Hull - Texas Jul 10, 2016
  • “ I have the Bren Tuning ECU flash on my 2015 BMW S1000RR and it is unbelievable how fast this bike is. This tune is the best thing I got for my bikes. I have also did the Bren Tune for my 2014 BMW S1000r for which it just made this bike really nice. Bren Tuning is the best. ”
