One thing to remember is that the name on the filter may have very to do little with who actually makes the filter. The names are bought an sold. Fram is a classic example. It's been through something like ten different hands over the last few decades. The current owner is making about the worst filters on the market for the base model Fram. The bottom of the line Purolater's are way better. In today's world Purolator is unbusual as they actually make filters. They make flters for several other brands as well.
That said the Fram bike filters are OK. I put plenty of them on my XR600.
As far as I know no OEM actually makes a filter. However, they have a decent filter made for them. The only down side is the cost.
Most overly obsess with oil filters. I put about 100k miles on my first two XR's and they did not even have oil filters.
