Check out this very interesting articl on MotorcycleClassics website: https://www.motorcycleclassics.com/classic-italian-motorcycles/mystery-mv-agusta-175-zm0z14ndzkel/?r=1349D5825612I8V
It is about a MV Augusta with a hydraulic continuously variable "gearbox." (There are no gears in it.)
The article states that probably only 2 of these bikes were ever made.
In the 80's Husqvarna made an automatic transmission enduro. I wanted one really bad, kept waiting for one to be available. My 'friends' talked me out of it. I think the were afraid they would have been too jealous.
