Funny what you find whilst searching for something else. I found this Ducati Performance (Steel) 38 Tooth rear sprocket for 520 Chain Part No. 968359AAA Same as this one: https://www.ebay.com/itm/254851080012 I've no idea where it came from. It looks like it's had very little use, but does have marks etc from minimal use and storage. As you can see the coating hasn't even worn off in the teeth, so as far as life expectancy it's basically new. £20 collected from Clanfield Hants, or £25 posted within the usual 'normal' UK limits. .
