Hi Marshy,

One of our dealers notified us about this thread and I would like to find out more information please. Is this Superlite rear sprocket being used on an older RSV?

Most all Superlite RS7 Series steel sprockets have a recessed face for weight savings but we recently found out that this design will not work on older Aprilia RSV/Tuono models from I think 1998-2003. Aprilia rear sprockets mount differently compared to other brands like BMW and Ducati so we revised the 520 pitch sprocket to have a full thickness center along with a recessed middle section. This allows the sprocket to mount just like the stock 525 rear. Without the thicker center, the sprocket will be pulled to close to the swingarm causing poor chain alignment and rubbing issues.
