Don't get me wrong,i'm not coming from the Yamaha filter angle more K+N,i'm resigned to paying the going rate for a DNA stage 2,but see no reason to pay though the nose for a stage 1 as opposed to a K+N,i'm not even suggesting that the DNA be reduced to the same price,but for heaven sake make some kind of competitive effort, charging what they do for the 1 is just a P take.

Re K+N I run 3 other bikes and have one in all of them.
