I bought this sprocket to lower my gearing a little, which it did, but I prefer the longer gearing. :Wideyed: It has done approx 300 road miles. 39 teeth which is 1 over standard; the pitch is also standard at 525. Same as advertised here >> Ducati 1198 1198 S Corse 2010 Rear Sprocket 39 Tooth 525 Silver Inner Diameter | eBay Pics attached. I paid circa £90. Will take £40 posted to UK.
