I just picked up my wife’s 2015 sportsman 570 SP LE from it’s first service. We stopped to get gas and I did a quick walk around in the parking lot just out of curiosity. I noticed that there was no brake assembly on the left rear axle!! Is this normal? The front has two. It looks like it was never installed. There are no brake lines dangling or marring from bolts being installed. What is going on here!?!
