I bought this filter years ago for my Hornet 250 from Autobarn when I was a mega-newb and planning my first oil change. I asked for a filter referencing that my bike has the same engine as the CBR250R. If you can't see where this is going, they gave me a filter for the single cylinder CBR250R circa. 2011, not the inline 4 CBR250/R/RR screamers from the 90's. I hate to see anything go to waste. It replaces: Honda 15410-MM9-003 and 15410-MM9-013 Yamaha 3FV-13440-00 Kawasaki 16097-1061 and 16097-1063 Pick-up from Cranbourne.
