John Deere make a nifty little 20 amp permanent magnet alternator and
likewise a regulator that should be inter changeable with the Ducati
one. Should have JD reliability.
Part numbers are AM877557 for the alternator ($160), and AM101406 for
the regulator ($67).
Good article on the above:

I put a capacitor the size of a beer can in mine. It's 57,000mF. But I had
it in my junk box.

Yup Noel, I'm a ham. I got the capacitor the size of a beer can from an old
power supply in my junk box. Bought the 50# power supply at a ham auction
for $0.50 and have stored it for 15 years just to use one part on my Kitfox.
Anyone need a 30# 8 Volt transformer?
