Yamaha—Motorcycle—Rear Suspension Arm Breakage
What are the defects?
It is possible that the rear suspension may collapse during riding due to the bearing installation part of the suspension arm breaking. It could become damaged by a stress corrosion crack that is caused by a remaining stress at the bearing press filling part and a corrosive attack on the surface of the stressed area by a corrosive agent such as that which is used to melt snow.
