MWR Velocity Stacks - Aprilia RS 660 2021/+ // Tuono 660 2021/+

High Performance double cone Velocity Stacks for the Yamaha Aprilia RS 660 2021/+ // Tuono 660 2021/+
The set is co-developed by KRT & KHI , they tested four different configurations and the best option conserning both road & race use is become the current set MWR-VS-400 , looking at the best performance , most midrange power / torque and 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 the do not show us the powercurve but KHI told me the power was down only 0.7% compared to the factory Stacks
