Overview

The MWR Velocity Stack Kit is an intake component set co-developed with KRT and KHI for Kawasaki ZX-10R and ZX-10RR motorcycles. These stacks are constructed from engineering-grade polyamide PA12 nylon to optimize intake airflow for both road and track applications.
Show original supplier description
The MWR Velocity Stack Kit is an engine intake upgrade designed specifically for 2021 and newer Kawasaki ZX-10R and ZX-10RR models. Developed in partnership with KRT and KHI, this set was engineered by testing multiple configurations to identify an optimal balance of power, torque, and engine response. These velocity stacks are constructed from durable engineering-grade polyamide PA12 nylon to withstand high-performance environments. The kit aims to improve the overall smoothness of the power curve, providing enhanced mid-range torque and improved peak power output compared to the stock intake configuration. Installation is straightforward, requiring the removal of the original factory stacks and direct replacement with the MWR components. This modification is suited for riders looking to bridge the gap between street and race-ready engine performance.
