Harley Davidson Iron 1200 Rear Shocks Preload Adjustment

A Quick tutorial on how to adjust your 2016-2021 Sporter Models. In this video is my 2018 Iron1200. For years I've been riding on the 3dot preload because the dealer never told me to adjust it. The ride always bottoms-up when I hit a little bump on the road. After the adjustment, the ride has dramatically changed and it's very smooth now.
