Overview
MWR-VS-435 : Velocity Stacks for the Kawasaki Ninja 400 / Z400 / Ninja 250 / Z250
The set is co-developed by MWR, KRT & KHI , they tested four different configurations and the best option concerning both road & race use has become the current set MWR-VS-435 , looking at the best performance , most mid-range power / torque, Top end power, and the overall smoothness of the curve.
The tests were done on the bikes of KRT (WSBK) and Team Green ( Superbike Factory Team Japanese Championship) and of course they will not show us the powercurve but KHI told me the MWR Velocity Stacks work and they for sure wouldn't use them (while winning WSBK title after title with MWR) if they didn't!
Of course pretty soon we will powercurves / dyno charts to show from independent teams, shops, and riders for us to share, but for now you'll just have to trust us :)
Installation is very easy , remove the original stacks and you can install the MWR stacks
