Regarding the 2013 seats, I think the older seats looked better. Maybe not as comfortable but a better design. Maybe it's just the angle but just looks too flat to me. Check out the Rich Phillips black seat at lowbrow customs- goes for $114. I bought one for a moped bobber conversion- sadly couldn't get it to fit but it's a real nice seat. If my Heist doesn't ever sell :( I may change it out. The beautiful brown solo seatI had on my Heist pages ago here is now on the moped.

You might have to replace the bushings/mounts. The older Heists actually had some sprockets sheer off on people. That is if you haven't already. Best, Xeta
