Yeah someone messed up at the Ducati warehouse. I wanted the lightweight (drilled out) 14T sprocket and I got the standard (undrilled) one, even though he label on the package had the lightweight part number. I ended up just using the standard one.
I purchased my ultra-light, drilled, high tech Vortex 14T sprocket from Bellisimoto.
I am told that there are two types of front sprockets for Ducatis. Regardless who you order from, be sure to specify that you need the sprocket that is attached via one large nut vs. the sprocket that requires a plate and two small bolts.
