"front and rear moving cheeks allow for more gear range" true but if the motor moves far enough u essentially have the same thing on a single cheek system. The reason derbi dominates variator tech is becuase it has 2 large pulley cheeks that should provide greater range then a french bike.
scooters aside, I still think the french clutch tech has alot more potential then usa tuners have given it time, and that the single swinging motor system can best a derbi in the long run due to its moddability and super clutch.
LA resistance!!!!!!!!!!!!!!! we will prevail!
