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-400, looking at the best performance, most mid-range power / torque and the overall smoothness of the curve.

Tests were done on the bikes of KRT (WSBK) and Team Green (Superbike Factory Team Japanese Championship).

Installation is very easy , remove the original stacks and you can install the MWR stacks , you need the original mounting sleeves for installation.

Note: These stacks do not fit on the 2016-18 model , the throttle bodies are the same but the original installation sleeves are changed. Please see MWR-VS-400 for the 16-18.
