Anello di tenuta INH G20x26x4 (Avviameno) - Junk ring - for the kickstart shaft on all 750GT, 750 Sport, 750 Super Sport, 860 series and all 900cc bevel drives under part # 93783.2026 as well as swingarm pivot bearing seal for all belt engines. This fits behind the alternater cover into the right side case in front of the kickstart bushing and is a typical cause of oil leaks in that area. May fit other bikes, we will continue to cross check the manuals when we find some time..
