Rear wheel rim for Viper 125-200 cc motorcycles and similar (China, Minsk). The rear wheel rim is a cast alloy one, and the tire and the drive sprocket are mounted on it. The size 18x1.85 means a rim bead seat diameter of 18 inches and a width of 1.85 inches.
The rim is replaced after hitting curbs and potholes: cracks, dents and runout cause vibration and loss of tire pressure. When choosing, check the seat size and the way the sprocket and brake are mounted against your model.
