Yamaha Center Cap Washer Plate 90201-125J7-00. This is the washer needed to hold the center cap to the rear hub. This fits the 85-88 badger 80 yfm 80, all champ 100 yfm 100 models and even the raptor 80 models if you wanted to add center caps to it. I have a lot of other parts available in my store.
