Is the Supersprox just the sprocket, albeit in 2 parts? The main advantage of the Renthal is that it replaces the standard Ducati carrier as well as the sprocket which will prevent the cush drives destroying the hub, as they are prone to do with the SSA bikes.
You can also just change the sprocket without removing the wheel and the hub assembly. handy if you do track days or just want an easier life.
The Renthal sprockets are much cheaper too. You can buy 2 or 3 for the price of a standard ducati one.
