BT Moto M Race Velocity Stacks (21-24) BMW M1000RR (K66) & (23-25) M1000R/XR,

21-24 BMW M1000RR (K66) / 23-25 M1000R/XR (K67) 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 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 (K66) and S1000RR (K67) airboxes. As we have exhaustively tested this in both 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.

*VELOCITY STACKS DO NOT REQUIRE FLASH PURCHASE BUT IS RECOMMENDED FOR ADVERTISED RESULTS*

BT MOTO M RACE VELOCITY STACKS

Red 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.

Made for an OEM fit, the BT Moto M Race 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.

Below is our custom flash with BT Moto velocity stacks versus stock and Stage 2 with no stacks. You can see the bike gain power all the way through the RPM band and even resolve factory power dipping. Up top you can see a significant gain. All on pump gas 93. Same day testing on the same bike. All models M1000RR 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 - BT Moto Stage 2, 93 Pump Gas, Bolt-Ons, BT MOTO STACKS

BLUE LINE - BT Moto Stage1 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)**
