Description MWR High Performance Velocity Stacks for Yamaha R6 → ’06/’24 The original mechanism, bushings and plain bearings must be transferred from original to MWR stacks No Modifications needed For optimum performance run with MWR Performance Airfilters MWR VS 900 Dyno Sheet Std vs MWR-VS-900, R6 08 MWR VS 900 DynoSheet R6 2021 Std vs MWR-VS-900 Velocity Stacks Yamaha R6 Velocity stacks optimize air intake and boost performance in motorcycle engines. Typically installed on the air intake side of the carburetor or throttle body, these components work in the following ways: Smoothing Airflow Velocity stacks streamline the path of air entering the intake, reducing resistance and turbulence. This allows the engine to breathe more efficiently. Increasing Air Velocity The stack’s shape, usually a gradually widening horn, accelerates the air entering the engine. As air passes through the stack’s narrowest part, it speeds up, filling the combustion chamber more effectively. Enhancing Air-Fuel Mixture By improving air intake velocity and airflow smoothness
