+1..The air filter and the "major hassle" involved to change it is probably one of the biggest gripes posted by most riders...I have a K&N filter in my 2013 F6B, which I purchased in the winter of that year...Had the bike custom painted before I rode it home late in the year, and as the dealer had it torn apart for painting, I had them put in the K&N..With only 14,000 miles on the bike now I am hopeful it will be a while before I need to service the filter...I might even talk myself into a new bike by then, but so far will stick with my current ride....Regards and ride safe
