Yamaha and Harley - which models?

Sorry, my first post was in a bit of a rush, couple more photos below. They now belong to a friend of a friend who inherited them through a loss in the family. They knew I had a bike so asked my opinion on where to sell, how much, etc. I don't really have a clue to be honest. I'd assume they aren't running, or at least not fully roadworthy, but apparently come with loads of parts.

I actually quite like the Yamaha but I've just bought a new push bike so can't justify it (or can I?).

Incredibly helpful, thanks.

If I do end up going 'round, I'll post more photos/info.
