I use std oem filters as I haven't heard anything bad about them. Some members here have clocked up lots of kms with no issues. I change my oil and filter every 5000km and its not worked particularly hard, and no probs or issues. I'm just interested in what people use and like most people I dont want to spend $70 on 4 litres of oil if I can spend $30 and have no ill effects , but before doing so I like to be armed with as much info as poss before deciding. I like your idea of a remote filter if your gonna to thrash it round a racetrack but for everyday use commuting in and out of work as I will be from May and considering the age of my bike then I cant see the point. With the remote system realistically you would surely have to have bike with the remote system and another standard and run them identically til one self destructs to see if it does make that much of a difference.

The difference between a good or bad filter is only a reference point. Filter should filter the oil period. And they are pathetic at it. You changing oil not becuse it has "worn out" or "broken down" but because it become a soup of bits that you filter can not catch. While in the last 20 years the oil technology made enormous developments, the filters made virtually a zero progress. I think the reason behind it is that they want you to buy and change the oil as often as possible because that is how they make profit. So why invest in better filters?
If you really want to save money install a best filter you can find and do the oil changes based not on kilometers but oil analysis. Standard test cost only about $45 and there are labs in every capital city.The results will not only give you indication of the oil condition but also the state of your engine.
