Something happened on my 2019 Road King Friday. I was going across a 5 lane bridge 150 ft high , I looked in the left hand mirror and at the same time the front end shook, this was at 40 mph. It felt like the bike was turning left and I couldn’t bring it out of the turn, no cars were coming so t tried to make a U turn but ran into the 6x 4 inch steel guard rail. Pitched me over the bars and onto cement walkway. Left leg hurt . I don’t know how bad the bike is it was laying on the crash bars . I had just put them on the rear too.
