Double post don't kill me. I don't want to pull the trigger too quickly (and bike isnt within my reach to check) I like the look of the UNI filter a lot, as well as it keeping out dirt more efficiently.
However I see that the the uni's posted were 50MM where as the K&N both have a smaller I.D. of 35MM

I'm lost af help lol.
