I'm a Mobil1 fan, as well. I have used it for over 100,000 miles in previous bikes. I also use the M1-110 filter. It's longer than the OEM filter, but fits fine with the Ninja 1000 fairing. I know there is a question of whether the longer filter is a good choice for this bike, but I figure since the 110 is also used in Japanese automobiles that's a good recommendation for filtering capacity.
