WHY CHOOSE BT MOTO

2010-2024 BMW S1000RR/R/XR and M1000RR/R/XR (K67, K66, K46) BT MOTO M RACE VELOCITY STACK KIT

Same gains and same horsepower, only issue is anodizing did not pass quality control. These stacks still come with a full warranty.

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 (if available) 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.
