Which Is Best Air Filter?

[humbussa]

I run a DNA they are all much of a muchness, I even pulled out the paper out of my gen2 stock filter and left the mesh in for a test run to lean it out a bit more it worked but the bike only ran only a little leaner on the A/F readings nothing to get too excited about.

hey as Simmo points out not much gain...the originals are the way to go unless your racing all the time and you need to gain those extra 2hp but for normal day to day riding stick with what Suzuki put in their best road bike ever!!!
