'01 ZX9r Oil Filter question

I have recently picked up a 2001 model ZX9r and was givign it a look over (as there is little else to do with all of this rain around) and I noticed that the oil filter is a 6B21Honda filter. Is this a bad thing that it is a Honda filter? Should I swap it out? From what I can gather the filter is for a CBR600 I think.
Any help would be great. Thanks.
