I bought an sv1000 with a Galfer wavy rear disk fitted. 5K later I noticed a large crack in the disc. Galfer warantee only covers discs if fitted with galfer pads but I discovered mine had been fitted with the OE Nissin pads.

A Galfer dealer who I have been addressing the issue with tells me that this sort of damage is "relatively common" on discs run on standard pads. Sounds dangerous to me and whilst it is clearly stated on Galfer promo material that warantee will be invalidated by running other pads I have not found the dire warnings of potential life threatening consequences that I would have thought would be appropriate.

Is it a well known fact that wavy discs + standard pads can ovetheat and crack? am I the only one who didn't know? is it common or was I unlucly? I feel lucky to have spotted the crack before it went all the way and locked the back at speed.
