As a German manufacturer I would think that YT would adopt the Bosh motor.. but I am hoping that they will wait until Bosh announce a new motor. Got to be soon..If it is as good as the Capra it will be a winner
YT have moved away from Shimano in recent years.
will be interesting to see what motor they do choose.
I personally can't see past the intutition and smoothness of delivery/tail off of the Shimano motor now I'm so used to it.
