The Honda filter, like most OEM filters, has a by-pass valve in it for colder temps. When it's cold outside and the oil is so thick it will not flow through the paper, it allows the oil to push a spring controlled valve, and bypass the paper filtration. The paper could be torn from the excessive pressure of thick, cold oil.
In the CB1100, there are 2 separate chambers. One sends oil to the filter, the other to the cooling passages around the spark plugs.
I don't know if that other filter has a bypass valve in it.
