Thisis common, my concours rotors did it and now my versys 1000 rotors are pulsing. As you're learning, sand the rotors and free up the bobbins. good until next time.
It's looking like it'll be something I need to do at every front tire change, at minimum. I don't know if it's a pad issue or road grime.

All I do know is regular shop chemicals won't touch it.

After you solve the dirty disc (sounds porno:wink2:), I recommend EBC HH brake pads. They work miles better than the stock and don't glaze my EBC discs. The discs were replaced by the DPO, he claimed the OEM warped.

EBC HH pads fixed it. Thanks.

freeing up bobbins, so they can move? i don't think so. there is nothing there to be freed, and they are not supposed to move. I have FULL floating rotors from Galfer and even in these the bobbins do not move. if a bobbin moves, it means it is damaged.

My OEM pads were at 67,000K and stiil had life in them. Regardless, I finally replaced them with the EBC double sintered. A couple of weeks in now and no more front brake pulsing. With the OEM pads after sanding the disc they would start pulsing again after a day without fail. Very annoying. I also checked the bobbins once a couple of years ago as what I've read says they need to have some give. The EBC have more bite as well for stopping. Should have done this a long time ago instead of waiting for my OEM pads to wear out!

Ya, I've heard that for decades now. I've used HH pads on my last four bikes and have yet to wear out a disc. 120,000 km on one of those bikes, the discs were still in spec.

Unless you're doing regular track days and attacking the corners with aggressive braking, HH pads are not a concern.
Not being able to brake with authority and confidence on the road is definitely a concern.

That kind of my thought as well. HH pads may wear out my rotors, but that's wear from use. Imagine how many bikes are in wrecking yards with perfectly good rotors because someone couldn't brake properly.

Spoiled alert: I've never seen a bad rotor in a motorcycle wrecking yard that wasn't seriously bent.

I can't quote the mileage (it's on my '08 in AZ), but I replaced the front-discs on my '08 when they measured at below the wear limit, several years ago, and as it has 92,xxx miles TOTAL now, probably around 70K miles, or 112K kms.

That is still respectable mileage from a disc. It all depends on 'braking time', riding habits, weather, road surfaces and riding environment. Hell, even tire choice might enter the equation. Urban riders spend a lot of time braking and wear increases further with aggressive riding. I rode 250 km today and did less braking than I would have in 25 km of city riding.

It's a matter of individual experience and generalizations never work for motorcyclists- we're all different, some might say weird!🤪

I still had almost 1/8th inch left on my pads after 67,000K, shows my riding style. In the city,I have learned to ride"like Im in a parade". I do crank it when Im out of the city. Already laid a bike down and slid when I was young. If I can get rid of the pulsing thats all that matters to me. I like to feather the front brake and like it to be smooth.
