Front sprocket lock washer for Viper 125-200 cc motorcycles and similar (China, Minsk). The washer locks the drive sprocket on the shaft, keeping the nut from backing off under vibration and load.
Replace it if it is deformed, cracked or the bendable tabs are damaged. It is recommended to fit a new washer every time the sprocket is removed: this way the nut is securely locked.
Country of origin: China. If you have trouble choosing, call the store: we will check by model and year of manufacture.
