There was this anime I can't remember what it was, I was around 8-9 years old. It aired, probably on Hero TV (Philippine-dub anime channel). A ritual scene, with a nude lady. Then she was (assumed) rescued from a guy, riding on a motorcycle.
We don't know how old you are, so we don't know what year it was when you were 8 or 9.
I'm going to assume it was an adult anime. I was around your age when I saw Crying Freemen, & that's permanently burned into my brain as well.
Motorcycles & nudity went together like coffee & cream in 80s animes. So while that probably narrows down the decade of the anime, unless you destingly remember it having a 90s or 00s art style. You'd have to look up every adult anime with motorcycles ever commercially released in the Philippines for cable broadcast, Removing internet fansubs from the equation should help narrow down the results further.
