"...and make sure the buyer knows that the bike has a crash" 

Er, yeah, right...make it difficult to sell and devalue it after having it properly repaired?

I don't know the Thai laws, but in civilized countries it is the duty of the seller to inform the buyer if the vehicle was in a major crash. I think it's only fair to mention these details.

At the same time, you can present the invoice of a qualified company that it is now repaired and straight.

Or how would you react if someone sells you a bike which was crashed and he "forgot to mention" it?

Is it?   You mean that it's mandated by law for vehicles that have been properly repaired and are legally on the road, i.e. not rebuilt write-offs?   In which countries?

As in the OP, I'm not referring to rebuilt write-offs but I understand what you're saying.  Morally it would be a nice thing for a seller to do but that's just one of the downsides of buying a used vehicle, if I didn't check it out properly it would be my responsibility.

In the UK i use to buy insurance write off bikes and repair and sell I made profit in buy and sell not my labour time. 

 

In Thailand it can be done as a matter of course because labour is so cheap.

About 35 years, and that I would never drive a bike with any kind of repair to the frame.

I'll have to agree with you on that.  I spent 20 years a welder (aerospace, nuclear, etc.)  and 25 years a welding inspector.  Certified NDT for mag testing, dye penetrant, ultrasound, visual.  Had my own TIG shop.  So ..... I'd ride lots of slow bikes with a repaired frame, but not a 600 at speed.  If I welded it, and I rode it, that's one thing.  I would never weld one for anyone as a repair, and I'm a professional, or was.  If a hydraulic straightening machine is used it has to be a very, very, slight repair.  VERY SLIGHT!  In the 2-3 degree or less range.  And then, inspected for stress cracks after straightening, preferably dye penetrant, all paint removed.

Now I inspect beer.  To each his own.

Once insurance has paid, in the USA, it's sold at auction.  All vehicles.  It can be repaired but comes with what's known as a "Junk" title, or "Salvage" title.  It can only be sold 3 times, including the first salvage sale after repair.  That is THE LAW nationwide.  If two cars are salvage and put back together (one had a totaled front, the other the rear) the title has to state the salvage job was a full front/rear connected salvage.  Bottom line, if the insurance pays it off, it's life is finite after that.

But, that´s a great career change. I have found solace in that as well.

So is sudden catastrophic failure the fear.?

Has this phenomenon ever been documented.?

The 2006 Suzuki Gsx-r 1000 had a recall due to potential stress fractures around the head stock.

The repair that Suzuki chose was interesting.

The headstock is a part that is welded on to the frame in the first place I don't know what everyone is going on about, I took bikes to a specialist bike workshop to look at the headstock of a damage frame and they would say nah or yah simple as that. 

Plenty of custom bikes in the world where a frame modification has been made.

by professionals.
