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 RECOMMENDED FOR ADVERTISED RESULTS*
Red anodized and made from billet aluminum with our laser etched logo, 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.
**NOTE: FINAL PRODUCTION COLOR MAY VARY**
**Each stack kit is made specific for your bike model**
Below is our custom flash with BT Moto velocity stacks versus stock and with no stacks. You can see Gains over the entire RPM range. Absolutely no loss in the bottom or mid-range with these stacks. Whether you’re racing, or just a stop and go cruiser, these stacks will give you a noticeable pickup in power and overall ride quality. Up top you can see an even more significant gain than the mid range, and the power carries! All on pump gas 93. Same day testing on the same bike.
RED LINE – BT Moto Stack Tuning, 93 Pump Gas, Velocity Stacks
BLUE LINE – Factory Tuning, 93 Pump Gas
**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
Install Time: 1.5 – 2 Hours
