I will be surprised to see how this makes it to production. As most motorcyclists know, shaft drive is a maintenance dream — having it on a bike will be a thing of beauty. As a YT clip pointed out, there are side loads induced due to how the shaft output end mates with the unified 'cogset' that will require stiffening in the rear triangles of the frame. It also would tend to jump teeth under high power. So, even when production costs scale down, it may be never be a drop in replacement for the classic chain-and-sprocket. (My bike has belt drive and internally geared hub [Alfine 8-speed], but my dream bike is gonna have a Rohloff—Hmmmmm.)
