Ognibene "SILENT" Sprockets are the latest innovation from Ognibene's research and development department. The rubber profile applied on both sides guarantees noise reduction, which is at least 2 db less than conventional
Counter Shaft Sprockets. Not only are Ognibene "SILENT" Counter Shaft Sprockets quieter than standard aftermarket counter shaft sprockets but due to their shock reduction, Ognibene claims their design also help extend transmission life. Ognibene Sprockets are made exclusively of C45 steel and Chrome / Molybdenum.
