Only guy I knew well who rode one was the guy who taught the motocycle maintenance nightclass I went to. He was a proper hardened old biker; was riding 30-40k ever year, including through winter in the snow and ice, into his late 60s. He liked all bikes; Indians and 60s Brit twins especially, but he also had a first gen R1!
He had a shedload of bikes new and old, but his main ride was his a W650. Main reason was "it feels and looks like my old Triumphs, but it's reliable enough for my 300 mile a day commute." I am glad they made the bike as he liked it and it made him happy. What percentage of people in the bike buying public have any real need/desire for something like that though? I suppose my cousin commutes a fair bit on his early 70s Triumph Tiger, but that's not high miles at all and for him, it's the appeal of it being a genuine old bike that he likes.
