Overview
2020+ BMW S1000XR (K69) 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.

**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)**
