(10-19) BMW S1000RR BT Moto M Race Velocity Stacks

Finally after a year of in-house research and development, a proper velocity stack for the 2010-2019 BMW S1000RR.  While an extremely popular modification with Japanese bikes, BMW bikes always missed the mark with their adjustable factory geometry, and intricate airbox from the factory. As some may notice BMW has changed the airbox several times over the past decade and offered a racing airbox for their HP4 Race series and WBSK bikes.  Some of these changes were introduced for more midrange, top-end, race use and so on. After studying the differences of all these units, before and after data, and dyno data logging, we were able to create a scalable solution for race use with the factory airbox. We studied the current market and tested other 3rd party velocity stacks and found flaws that needed addressing. What we found was the current market offerings are pretty disappointing. They appear to be made without any sort of testing or consideration for long-term durability.  These 3rd party stacks utilize the OEM rubber grommets and tend to collapse under extreme RPM's and high airflow. Due to this we avoided this rubber gasket design. The 3rd party stacks were also designed too wide and rubbed/hit the adjustable stacks connecting arm for the servo motor and locked the adjustable stack at a “neither open nor closed” function. As a result some 3rd party stacks actually lost horsepower over the stock configuration. The other 3rd party stacks appeared to lose power and did not alter the air/fuel ratio at all. This is a telltale sign that it did not change airflow. 

Our in-house dyno confirmed our suspicions as these stacks did not make more power than the stock configuration. Our lower funnel kit gives the BMW S1000RR that little extra midrange and top end that could be the difference between first and second place when stacked up to an equally modded S1000RR.  This is a must have for full bolt-on bikes, or race engines. The shorter tuned stack gives the bike a unique and more aggressive induction sound and helps keep breathing easy at higher RPM's.For this product to work as intended your motorcycle will require custom tuning. It's roughly 7% at 12,000 RPM, interpolated to 18% more fuel at the RPM limiter as a baseline. 

**IMPORTANT INFORMATION**

For near stock engines (sub 215whp), a 2010-2014 S1000RR will need to use a 2015-2019 S1000RR airbox as a donor, by removing the center stacks from that model and applying it to the 2010-2014, along with our M Race Velocity Stacks. If you need to purchase the airbox from a 15-19, the part number from BMW is (13718561315). This will include the entire airbox as the stacks are not sold separately. We recommend you find it used somewhere.

Without the 2015-2019 center stacks, utilizing the M Race Velocity Stacks alone on a 2010-2014 S1000RR will not result in gains (as-is) without being a built motor 215+whp that supports that sort of airflow. The 2015-2019 center keeps midrange and top end in check on an average 200hp engine. 2015-2019 S1000RR's just need the M Race Velocity Stacks installed and some fuel adjustments between 12,000-redline set rpm.
