This is a 17 tooth front sprocket for a bevel drive twin with locknut and star washer. These parts are used but looking at the teeth, there is no hook to the teeth. Someone went through a LOT of trouble machining off the original teeth, milling out the center of another 17 tooth sprocket then welding the two pieces together. If you have always wondered how your bevel twin would do on the banks at Daytona with a 17 tooth front sprocket, here you go.
