My 2017 Z1000SX now has the symptoms of warped front disc(s). Judders when braking from higher speeds and slight grab/release/grab feel at low speed (<15mph) and light braking. I'm not a heavy braker - original pads are hardly worn. Bike has only done 10,000 miles  since I bought it new last year. I don't ride when the salt is on the roads, so it's unlikely to be anything to do with corrosion (the bike has no visible corrosion anywhere). I'm wondering if the discs are warped then will I get a new set under warranty or will Kawasaki say it's fair wear and tear? Rode my 40,000 mile Fireblade last night to compare and its brakes are totally vibration free even at emergency stop from 70mph and it's on its original discs (I've owned that from new too).
Any ideas, advice  or similar experiences anyone?
Update: Kawasaki Derby (not supplying dealer as they only got franchise this year and this is my first visit) are putting in a warranty claim for one of my brake discs as it's warped after all.

Only one disc? Shouldn't they be changed as a pair?  :112:

Good question.

Should be OK I think? Same spec and not much wear, still on original pads and the pads are only 50% worn.

I'll ask Derby Kawasaki for their thoughts about changing pair though.

No.

If one is in spec then there is absolutely no reason why you should change both.  The only real justification might be just to match wear, but wear isn't significant so it's just for convenience of making sure that they both wear out together.

Think about it, they are both acting directly on the same wheel.   It's not like a car.

Well done burty - that's exactly the same as Derby Kawasaki said - word for word!
