Honda's reputation for reliability was built in large part on those centrifugal oil filters. From the first step-through 50s, through the DOHC 450s, and still today as Tev62 says. I remember servicing tons of them, pulling off the filter or clutch covers, scraping out packed-in metallic sludge, sometimes 1/2" thick. They are remarkably effective but become less so as they fill up.
