Holy Brakeman! Mark's email made me go out and measure my disk against the limits in the manual. My radial grooves are barely visible and I have 52,000 miles. The disk is not grooved much and I never thought to measure it as it looks in good condition. The manual specifies a limit of 0.53 in or 13.5 mm. Mine is down to 0.45 in So I need a new disk.

Yes - a bit pricey at $60 but worth the price for me. Yes, but Kevin's comment is exactly right...pads are cheaper than the disk, and you don't have to wait 4~6 weeks for them to arrive on a boat from Japan! How many of you bought your GTS new (raise your hands!)? How many of you remember looking closely at that huge front disk, and noticed that it had radial grooves etched part-way into the disk surface? OK, now go outside (or to your living room :) and look at your bike now. Run your fingernail from the inside of the disk toward the edge...do you feel a "bump" about 6mm (1/4") from the outside edge--that's an indication of how much of the disk surface has been worn away. Can you see those radial grooves in the face of the disk anymore? If not, then you're about at the wear limit for the disk. Get ready for a ~$300 replacement. I replaced my front disk at about 42K miles. Everyone's riding style varies, but I tend to think of myself as being "light" on the brakes. <SNIP> Mark
