Try H&H, they sure are easy to find, almost every search engine search with the word
"KTM" in it brings them up. I bought Hiflo oil filters there for my 640 and they were a fraction
of what the KTM factory one's were. It's hard finding good discount places, let us know how
ps- My local dealer gives 20% off of list on branded KTM parts if that gives you a reference.
