So the two-speed gearbox is separate from the axle drive box? Can you show us a picture of the two speed box, so we can understand where it is fitted and what drives it please Rob? It makes sense if they offered the single and dual speed systems as options, since they'd use the same axle drive box in both cases, I suppose.

Did Honda fit those two grease nipples on the axle drive box, or did you add them yourself?
