Compatible discs

Got a warped front disc, no problem braking from speed but get that lurching feeling when pulling up. Just thinking fazer or tdm discs the same which would open up more possibilities of getting decent used ones or more aftermarket choice

Some Ducati's around the same period used the same size, pattern and offset as well as a number of yamahas including TZ's around that era.

have you tried taking it off and persuading it with a rubber mallet?
Cant hurt, you were going to bin it anyways

[cobbadiggabuddyblooo]

Quite often the bobbin get gummed up and seize up That hinder the semi floating nature of the disc.
Spray them all with a bit of wd40 and but a bolt through the hole an lightly tighten the nut and get the bobbins spinning free again and clean all the gummed up salt, brake dust and road grime from it.
Put that in your regular maintainence check list.

What Cobba said, I've got a Tuono with the same 'problem' I thought the discs were warped as the lever pumps at low speed, buts actually just the floating spring. Its a slightly different system on the Tuono but the point is the same. If the discs are warped you'll know about it when you scrub speed. I've got a ZZR600 as well and the discs are shot on that, its fine at low speeds but gets really unhappy if you try to brake aggressively at any kind of speed, its a hack not track bike so doesn't really phase me.
