X-Max 300 front disc warped...

...which I believe is fairly common?
To be replaced without quibble under warranty anyway, so not a great problem!

I had a spate of EBC ones warping a few years ago, but no problems recently. Whilst its no problem in the warranty period, it will be a problem when the warranty ends!

Mine did the same no problems they just put a new disc and pads on,
I'm not hard on the brakes so am keeping a eye on it but it's been ok since.

My pointed question will be - "Does the replacement disc itself have a 2-year warranty"!

I thought mine was warped from new but it only showed up from higher speeds

One of those interesting questions! My guess is that it will be covered until the end of the 2 year warranty period. After then, I assume parts have a 12 month warranty.....though I don't know why I think 12 months rather than any other time! Parts will have a warranty, subject to wear & tear of course.

Hmm. My front brake is "lumpy". At low speed the brake makes the front of the bike bob slightly. I am going back next week for the v-belt (proper one's arrived) so I'll ask serious questions then.

Is there a website I can reference citing this as "fairly common"?

Only that it seems to have been mentioned a few times on here - I haven't tried an internet search otherwise.
But those symptoms should definitely get you a replacement disc when checked by a dealer; assuming you're still in warranty.

7000kms on my xmax300 and front disc is fine. 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.

Inspected by dealer; confirmed as warped.
