How comfortable is the rear passenger seat pillion compared to the two up Mustang touring seat? I currently have the Mustang two up seat and and a Mustang solo without the backrest and am considering replacing both with the 17' super solo with drivers back rest (79446) and the rear seat (79110). I ride solo and two up equally and don't want to sacrafice ride comfort for my wife.
Mustang solo with backrest (79487) I have 14" passenger pillion (79488) which is on when needed. The lady behind me says: "Very comfortable." I went from stock seat/pillion to this combination so can't comment on Mustang two-up.
According to my wife the Mustang is heads and shoulders above the stock seat. Never had the 2 up. Nice to have the option of a different look with just the solo.
