Is that aftermarket or genuine KTM?
Your eBay ad says "OEM-Partnumber: 60030099000 *The OEM-Partnumber is listed for comparison purposes only". This other one on eBay specifically states "athena": http://www.ebay.com/itm/Full-Gasket-...-/200851282898
If I look up that OEM part# on a US fiche I get
Description: GASKET SET CPL. 03
Of course US prices on KTM stuff are often way less than elsewhere.
