(2026) BMW M1000RR (K66) BT Moto M Race Velocity Stacks

2026+ BMW M1000RR (K66) BT MOTO M RACE VELOCITY STACK KIT

With the success and amazing feedback we've gotten from our M/S1000RR/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 don't lose 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 (K66)  airbox. As we have exhaustively tested this in both airboxes and found dramatic power loss. Instead, we spent months testing and developing different stack designs. Since the new 2026 M1000RR is so unique, these stacks had to be unique to match it. With our FTCL (full-time closed loop) tuning, there's no need to worry about your bike going 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 M RACE VELOCITY STACKS

Black anodized and made from billet aluminum with our laser-etched logo, the BT Moto M Race 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, while achieving a perfect fit for the 2026 M1000RR.

Made for an OEM fit, the BT Moto M Race velocity stacks an aluminum ring clamp to ensure a tight fitment while also being easy to install. We also added the addition of a rubber o-ring to seat in the imperfect airbox to eliminate any leakage from the airbox. These are plug-and-play and require no additional modifications to your airbox to fit. Simply remove your factory velocity stacks and install ours. 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.

**Each stack kit is made specific for your bike model**
