Last time I looked at the mustang website, about a month ago, they did not offer anything for the Triumphs. That being said, if your buddy thinks he can help you get a custom seat, I'd definitely consider that. My best friend has a mustang on his Kawasaki Vulcan Classic, and even after I sent my saddle to corbin to be softened up, his seat is still a bit comfier than mine is.
