Variable exhaust valving... I wonder how they will control it? Vacuum operated or electronic. Probably help the torque off the line and hp at top end... I likeeee.

He was talking about a switch on the handlebars in the clip I seen on FB
They are going to release more details next week . Price some pics on bikes and dyno results etc
 
It's probably similar to EXUP valve on Yamaha Vmax, closes on decel high vacuum to get rid of exhaust pop

Bring back memories... my old 1992 fzr400 had exup exhaust... the sound was awesome... specially at higher revs
