Check out these, any of them do the trick? http://simplybearings.co.uk/shop/advanced_search_result.php?search_in_description=0&sort=2a&search_3fields=1&keywords1=10&keywords2=20&keywords3=5&osCsid=d942a89320c90fad97a614d277b1648e I always buy "generic" seals and bearings, usually from my local bearings place but I've ordered a few times from simply bearings and theve been spot on. I've paid £3.80 for a bearing KTM wanted £45 for and it was the EXACT same bearing make,etc.. Just didn't come in a KTM pack. If you want to replace the bearing with the single seal just buy a bearing the right size with 2 seals and carefully pry one of the seals out with a tiny screwdriver or something, the rubber seals come out pretty easy,obviously be carefully not to damage the bearing.
