Tiger 800 XC drop link stress cracks

Sorry if it is not in the appropriate place newbie poster...
I recently did the Trans-Lab with a buddy and during clean up this week I noticed what looks like stress fracturing on the Drop link. Dealer thought it might just be cast marks. I took it to a local Race Tech shop and he said it definitely was. I wondered if anyone else has seen this. I seem to remember that when I read some of the press notes on the Baja Dad race one of them broke one. I have not found an after market one so I have ordered the OEM for now. Anyone else heard about this?

My bike is similar

I'm no metallurgist but mine look more like casting imperfections than cracks to me. I will check out a new bike still on the showroom and see if it looks like ours.

Funny I did the same thing when I went to the dealer. Did not see the same marks and I annoyed the sales guy. :-)

I am not a metallurgist, but my staff does inspect castings. It look like a hot tear defect. A description below:

I re-read my original post and just to clarify the suspension tech said he thought it was definitely stress not from casting. I did bottom a few times on the skidoo trails in Newfoundland. :-)
The part was not $$ but with seals and bearings it adds up but $138US for piece of mind is not bad.

That was actually very informative. Thanks FJ!
A hot tear is an imperfection during casting. I don't see any tears along the circumference so I will continue to run it and add it to my preflight inspection.
