Checking the rider sag involves measuring the amount of suspension compression that occurs when the rider is sitting on the bike in a static position. The rider sag is an important setting that affects the handling and performance of the motorcycle. To check the rider sag, you typically measure the distance between certain points on the bike before and after the rider sits on it. This measurement helps determine if the suspension setup is properly adjusted for the rider's weight and riding style. #MXGP #Motocross #Suspension #MX2 #Dirtbike #YamahaRacing
