Just crashed my ninja 600. Two cars suddenly stopped in front of me, panicked and lost traction. Front wheel hit a car. It seems the neck is slightly bent without cracks. Took it to a shop that says it can straighten the neck without any structural issues. What's your opinion on this? Is it safe? Or would it be better to buy a whole new frame? Or sell the bike for parts? 

Just have the boys straighten it out...' be fine.

Thank you. Was reading on reddit and everyone says any slight bend is catastrophic basically... Which made me worried 

I think you know your answer.   Ask your gut............what's the first answer that comes to mind?   my feeling is, and I agree with you, your first thought is to either buy a new frame or sell it for parts.   Even if back home, I might do the same.  After an accident, things are never the same and i'm not sure it will be fixed to put your mind at total ease.   pretty big risk to take................especially on a bike with that kind of power.  

Straighten it, see how it rides after

I don't know because I don't have much experience with this.

There are frame aligning machines. I don't know if they have them here but I expect they would.

Photos would be good to see what you mean by neck. 

To fix the head stock is OK the call it a tug. 

I would be more concerned about suspension problems.

Check that as well.

Yes it's one of their services. I was mostly worried about the integrity after having it straightened. 

Metals strength after flexing changes a lot depending on how much has elastically failed.  Not an expert at all but I could tell when I would scrap the frame once I saw the  extent of damage close up.

The shop said they wouldn't do anything unless they deem it safe. But I have no clue 

I think I meant non-elastic failure.  

Glad your ok otherwise. 

It is made of steel.

Which does not just fail.

No cracks.

Good.

Farang think too mutt.

 

 

Can we see pictures of it ? Sorry to hear about the accident. 

Years ago i crashed my bike in UK, not my fault, anyway my Dad and i bent the forks back to straight using a plank of wood old fashion style, rode it fine after

Just wreck it! Pile it up in the dump and buy a new one.

And your experience with motorbikes is?

Find the price of the OEM parts online. Should take 5 minutes.

 

If they cost less than the peace of mind, buy them, if more expensive than your peace of mind, get it seen to by a couple of backyard, unqualified Thai guys. 

I would bring it to an authorized Kawasaki bigbike dealer, not just any other shop.

Depending on price of a new frame and inspecting the damaged one.

Frame can be magna fluxed, magnetic particle inspection or even x-rayed for cracks

My friend works at the above company and is a hard core motorcyclist

 

I've done bike frames where I'm from. X ray inspection on a changed head angle and rewelding.

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

As per others - can you post some pics?

A  newbie then.

Just saying if a new frame is fitted, then it will have a new number, which will need to be registered and changed in the book.

What is it you don´t get? Newbie after 35 years. Newbie, just because I do not trust repair on a bike frame.

Seems more to me, that you are the one having problem with the meaning of a simple word. On the other hand, maybe you just trying to be a bad a55

If it is not too expensive, then I would let them straighten it and then sell the bike (and make sure the buyer knows that the bike has a crash).

 

But it obviously also depends on what you do with the bike. Short runs to 7/11? Or do you use it like you are supposed to use a Ninja 600?

I just did a quick search, and you're looking at about Baht 50k for the frame...I don't know the year of your bike, but it seems it was used from 2009 up to at least 2017

Designed for race track.

Structural aluminum is also very suited to 

this type repair.
