Bought these '2nd hand', only test fitted to find out they were the wrong size (7.4mm) for the seller's bike. My bike also has the 9.4mm covers so... One has a slightly damaged O ring, you can reuse it from the OEM cover or buy new for a few quid (88640602A). Check your OEM cover thickness before buying! No returns/refunds. 90€ + shipping. A new set is around 150€ with VAT: https://www.cncracing.com/en/product/camshaft-cover-ducati.html
