The boards on the 16, are identical to the boards on my 08 m1000. AC needs to get the heads out of their ass in this area. Only reason I can see for not changing, saving weight. Cause the s**t I cut off was tin flimsy garbageSince you didn't ride it with the stock boards, you will never know just how much better those are gong to be. That is one of the main things I am doing, besides the narrowing kit on mine for this winter. Spent to many days kicking snow off of the stock boards last winter.
