Front brake rotor bobbins cleaning, freeing up.

Several threads including bobbins. Do a search in C14 chat. I tried doing mine but could not get them to rotate.

You can make a simple tool with washers, bolt & nut. The first time you try to rotate them its difficult but after that its a piece of cake. I do mine every year during winter layover.

On this specific bike, and brake caliper, I think there are a few things going on.

1 is we ride a lot.   2 is, the front caliper gets dirty.  That 4 pad design is a difficult one to keep clean.  When it's not clean, the pads won't retract, properly, and I think that's what ruins the rotors.

I do clean the bobbins, yearly, and at the same time, I also clean the caliper with a toothbrush and brake cleaner.  So far, so good.

Also, if you start looking at oem kawasaki rotors, they aĺ look the same, but have way different pricing.   I'm not 100% sure ours are the ones from the top of the quality pile.

I wasn't sure guys on here practiced this so I asked.
I've done this on every bike I owned.
C14 seems to have the tightest fitted bobbins compared to other bikes I had.

I just got(yesterday) a fresh disc under warranty for my Versys. The bobbins do not rotate by hand.
Some interesting measurements. New disc is 5.39 mm, the other is 4.95, the removed one was 4.85, minimum thickness is 4.80. Bike has 32k miles on it and still has half of the original pads left. Will probably need a new disc when the pads are done. 😟
Yeah, if you want true ram air tuning, you better be willing to ram some air! (SiSF)

+1.
I do mine while I change my oil. The time spent waiting for the oil to finally come to a slow drip and the bobbins are done.
