Noticed this a few weeks ago and now confirmed that my 08's front discs are warped, so I've ordered some new ones (OE). It's only done 8k miles. Anyone else got warped discs at low mileage. (Not that I'm bothered by this, just wondering really).
Can happen when the pistons don't back off properly when you release brake lever. Check discs on every ride to see if one constantly hot, even after a non braking ride. Clean pistons, push in , pump out a few times or strip and lube with red rubber grease.
Thanks mate. Pistons were cleaned a few weeks back, but maybe too late. This bike was also stored outside in snow for about 3 months when I was getting building work done - starting to wonder if extreme cold affected it too.
