yeah, I had that with my ZZR1400, the dealer said they were warped but in fact it was the mounting bobbins that were jammed with brake dust.

I believe it's a floating/semi floating disc, so could very well be the mounting pins/bobbins that are caked with dirt or brake dust causing the floating to stop. This will give a pulsating feeling through the front brake lever. Use brake cleaner to give the disc mounting points a thorough clean.

Think the discs are solid no bobbins but could be wrong.
I did wounder if the wheel were the disc mounts was true.

Re: X-Max 300 front disc warped...
New disc and pads fitted yesterday afternoon under warranty - now back to 'poor' front brake until it beds in again..!
Which takes a while, but it's excellent when it does.

Re: X-Max 300 front disc warped...
I did wounder if due to the brake being so poor until it beds in I had been
leaning on it more than was good for it when new and so the warping.

Ralph I doubt if every X Max owner with warped disc " lent on it more than was good for it". One of my mates with the 125 X Max only had rear disc warp.

Re: X-Max 300 front disc warped...
I have just had a second rear disc replacement on my Xmax400, @1000 miles after the original warped at......@ 1000miles. Replacemed under warranty again, another 11 months until 2yr warranty is up. Not a hard breaker, dealer say's the disc composition has been changed making them more susceptible to warping by overheating at 'normal' braking usage.
