MWR high performance velocity stacks for Yamaha YZF R6 2007-2021

New MWR R6 2007/2021 velocity stacks!!

Finally we beaten YEC after quite some time , at first we were looking in the wrong direction but finally we got it right

We tested them on track by World Supersport 600 teams and let them compare with the YEC and all of them choose for these configuration
Proven with domination (again) in WSS600 by MWR teams since Estoril .

It is quite well possible due to the construction of the stacks you need to leaner the fuel from the upper injectors (high revs) of the to two outside cylinders (less fuel blown away so more effective …. higher top-speed)
