I THINK a lot of the brake issues are dirty calipers. These bikes get some serious mileage put on them. Even after a thousand miles, mine had a serious dusting inside. I'd imagine a dragging pad would create some serious heat.
I also wondered abotu washing. It cant be good to shoot cold water on a hot rotor, right?
On the other hand, I'll offer a "shut-up". If you compare the brakes on thsi bike to what the 2011-2013 Ninja 1000 came with, these are night and day better. More power, feel, everything. I had to upgrade my Ninja because switching between bikes, and brakes, was difficult. The Ninja felt Flinstone style in comparison.
