Default Frame Damage, Problem or Not?

Hello guys,
I need your advice on that. My bike was rented, the guy got into an accident and one small piece of the front frame, left front fork, chopped off and now the bearing is exposed. Can this be simply welded and we are good to go, or will it never be safe to drive that thing again?

Your better off having the neck cut off and welding a new one on but only by a professional aluminum welder. You can also have it raked a bit.
Just welding that small piece back in May not do the job as they may not penetrate deep enough. The bearing is pressed in so you might have problems getting it back in without more stress back on that welded piece. By the time you get the steering assembly off you may see more cracks also.

If the steering stop on the lower frame neck (contacts bottom triple tree) this is not uncommon and there have been multiple repairs documented on the forum.
Some have reported re-welding the broken piece and others have machined a duplicate part and have rebored the neck for the lower bearing outer race if a machined part was required. The frame is A356 aluminum alloy and weldable.

I'm enclosing a couple of threads that come to mind of early frame neck repairs. A prerequisite before doing this work would be doing a thorough inspection of the neck area

This is another option I would not trust of frame where the nec has been re welded.

It is not about trust but about finding someone who is competent enough to weld cast aluminum. You just can't bring it to any Joe Shmoe and have him whip out his lil tig and "try" to repair it.

I did the weld repair on the bike in the "knocked over & run" thread.

Is it not innately unstable now when the frame was once broken? I actually would be interested in welding a slightly raked neck. I live in Los Angeles, do you know any guys who could do that job properly and where do I get the neck from.
Thank you guys!
