I believe the rumble strips have all been smoothed out even more for the motoGP bikes now. Compare Clarks picture with the recent one with Rylans car.

It looks like the rumble strip is smoother, but the angle and transition to the surface beyond looks much more abrupt.
When I was taking the line in the previous picture, I swear it was not violent at all.

Hey all, a little more light being shed on the failed brake line. I've been trading PM's with SR71BB, and through the discussion it came to my frontal lobe that I just installed KW coil-overs in July. When I disconnected the shock top, I let the suspension droop and did not do anything to limit that suspension travel, letting it droop until .. well something stopped it.
I don't recall there being obvious tension or strain on the brake line, but SR71BB says that this definitely strained the brake line and I should have done something, like a hook or zip tie, to limit the suspension travel.
I followed the very fine DIY guide by gfacter but I don't think this is mentioned in that particular write-up.
What's everyone's thoughts on this?

I don't know for sure, but I doubt HIGHLY that Honda designed the brake lines and fittings themselves. It is far more likely that they source their brake lines from a large company that makes OEM brakelines for various different car makers. It wouldn't surprise me if that same company makes and sells SS lines to the aftermarket.
I don't think the OEM vendors for rubber brake hoses are in the low volume SS brake hose aftermarket business. It wouldn't be profitable for them.

You would have to have somebody familiar with metal fatigue look at the part that broke in order to get a really good diagnosis.

I don't know if they changed it or not for the bikes, but the way it used to be was pretty nice -- if you just nibbled the curbs a little bit then things were fine, but the farther you went into them the more they started pounding the hell out of your suspension. It was more progressive than many curbs are.
Still better than no curbs, though. My local tracks have very little curbing and people tend to crash when they drop wheels off and don't know how to handle it.

There is no metal fatigue to examine, it was the rubber hose that broke.
Is the material deteriorated in any way (rotten)? If so, there was probably some chemical contamination.
Otherwise I think you just sliced it on something sharp. Could have been debris on the track. Might have been while you were working on it, and then it eventually failed when it was hot and at very high pressure.
Is the rubber reinforced with metal or fiber? Can you tell if they were cut? I suppose it is possible that fatigue could break the reinforcing fibers (assuming there are some), then the rubber could have failed. Rubber itself does not fatigue, but it does heat cycle and age through oxidation and UV exposure.
And if it was sliced by something sharp, then yes, I suppose SS lines might have had some protection to offer. What I said before was assuming it was the fitting that snapped, not the line itself.
