I don't know that much about the difference in performance or reliability on one or the other I do think the bdm design looked good and as some said the other looked old style ,but im pretty happy with the one they choose to use I kinda like the fat big powerful look it has to it.and I think with the 300 rear tire it kinda makes the whole bottom of the bike look fat and well proportioned one sorta just goes with the other . now would you guys want a big breasted woman with a skinny little bottom, not me big breast gotta have some butt to go with it .just happy to see the dogs gona roam the streets again ,every body have a good day.
