Front A arm bent?

Can someone help me and make some pictures of how the front should look.

I had an accident where my left fork is broken and I have the impression that the ball joint and A arm might be bent as well. The front tire seemed to be to close to the engine than I remember it to be.
My ball joint wasn't in the best state but it look likes it's not in the right position, I already removed it and it feels broken, very loose in some locations.
The A arm (or leading link) looks to be bent but I don't know if it is meant to be at an angle or not.

I'm absolutely loving this bike, drove it for 10.000 miles since I bought the bike in May 2016 and want it to be riding perfect again so any help is more than appreciated!
Thanks in advance
Joris

Re: Front A arm bent?

That stuff is all trash. Welcome to the site by the way! Plenty of BMW motorad parts places in Germany that have used parts. The upper scissor linkage may be suspect also. There are spots that can be measured to tell if things are bent. I do not know them but have heard about them. I'd also look for a low miles shock to seal the deal for fresh up front.

Re: Front A arm bent?

Welcome to the site, and its difficult to say from the photo, but I think you've got some issues there,

here's a view of my bike taken when I was replacing the front shocks, don't know if it helps,

Thanks guys, looks like my parts are crap indeed, my A arm is bending the other way around and the ball joint isn't close to looking like CJS350's one!
Will be on the phone tomorrow to ask an used parts company in The Netherlands if the stuff on their site is still available

That A-arm is pretty stout, if that's bent you should have your frame checked.

That is where those reference measurement points come to play.

Re: Front A arm bent?

What year is that bike? When looking at used parts for the front end such as the trailing arm one should be aware that the trailing arm was changed after 09/03.

And so was the front shock length(?)to accomodate for the different trailing arm.
