I want to know hoy KTM get away with running that input ratio on an Alfine hub. (not sure if >that is the Alfine model or not but it is available with Alfine).
the gearing is in the box at the bottom bracket. It's a Pinion p18 gearbox.

Ah ok, my mistake, I thought that was the electric one.
The Macina runs a Nexus, Alfine or Nuvinci depending on spec level but all the models have what looks like the same, very low input ratio
I'm pretty sure that if that's not 1:1 then its larger at the rear than at the front.
Not even sure how that gives useable gears, I spin out pretty easy in top gear of my Alfine with a 32:18 or 1.7777 input ratio.
When I bought my hub it was used so no manuals and I did find it hard to get hold of anything official about the input ratio but there was a lot of chat on forums etc about 1.6 being the lowest that Shimano recommend.
