Sprits with a little castor oil will help to keep thing moving nicely.

K&N is still a great product.

And by using Ducati parts I wont be voiding the warranty.
Sorry but don't let the SL marketing hype fool you. The filter they use is made by SF Sprint. You can pick them up on Ebay for less than Ducati would most likely want to charge you. Since it does not use a paper or sponge element it should last a long time, only requiring compressed air to keep it clean, during routine maintenance. Most of the WSB, and BSB teams running the 1199RS use them.

In my experience, a high quality chain and 520 kit will always outlast the stock 525. A DID 525 chain has a tensile strength of 9220 lbs. The 520ERV is rated at 8660. If tensile strength is proportional to longevity, the 520 is 93% of what the 525 is. Of course I'm ruling out the sprockets, but still, a high quality 525 isn't going to last as much longer as some might think it will. Of course, tensile rating only factors in chain stretch, not o-ring type, but I've never had a chain link kink before it was stretched beyond its operating limits, so tensile strength is typically the proverbial 'weak link'.

A 520 chain is 81% of the weight of a 525, though (3.3lbs per 100 links vs. 4.05 lbs).

My stock chain needed an adjustment 1-2 times between every tire change. My 520 AFAM/DID ERV3 needed none in between tire swaps. And after 12,000+ miles and 8 or so track days is/was still in great condition, with no loose spot/tight spot issues. The 520 also gives me more clearance when I need to get an allen wrench behind the bolts for my rearsets, too!

No doubt a 525 will last longer than a 520 if they're both the same, but chain manufacturers put their best tech/materials/heat treating, etc. into their 520s, which gives them the best performance vs. size ratio.

I have just installed a 520 set up on my R, and I was skeptical on any gains.
I went with the light weight steel rear gear, I wasn't looking for the lowest weight as much as gear selection.
BUT the biggest gain that I noticed immediately was less rolling resistance.
The bike pushed around easier and you can actually feel the difference on the street as there is less deceleration when you get off the throttle.
Just my 2 cents.

WE should compare apples with apples. A 520 setup do not only have less torsional strength as my learned colleague so succinctly put it, but also proportionally smaller load bearing surfaces, but then each to his own. It is your money, you decide what kit you want to use.
