Hi, unfortunately I had an accident with my old Koga Miyata Exerciser road bike with a CrMo steel fork.
Is it still possible to straighten the fork, or would I need a new one?
Thanks a lot in advance for your help!

New fork required unfortunately
This is fubar, I would not trust the frame any more either.
that looks pretty bad, the fork is cooked and the frame might be damaged as well. Consider just getting a new bike if you got this one used.
New fork. IMO, the fork is too important for control to be going cheap on.
It is now a death trap. New fork. Sorry.
New fork.
Have a close look at the frame, too! If there are sny cracks or deformation at steerer tube, top tube or downtube, the frame is also toast. (Could be repaired by a frame builder, but in 99.9% of cases that will not be economical.)
To check for deformation, run your finger along the the tube. You will be able to feel deformation that you cannot see with the eye.
It’s steel, so it probably could be straightened but if a fork fails it’s usually really bad for your face. I would absolutely replace it.
Never any question that the fork is toast but there is a question on your frame. If the bike has taken a heavy enough impact to bend the fork like that there is more than a good chance your frame might be damaged as well so it needs inspecting by someone who knows what they are looking at to see if its safe to use any more.
Add a knife to that fork, and some butter, for sir that is toast
Back in the day, we used to straighten steel forks, Park even made tools for it (FFS-2 and FCG-1). But the fork is forever compromised and could fail so I doubt that any shops would take on the liability of such a task anymore. Buy a new one.
As others have mentioned, also check the frame for any ridges/buckling in the area under the shifters and up towards the head tube lug.
The fork is definitely compromised. It might hold up if it was straightened, but it might not, and the alignment might never be correct again.
It looks as though the damage may be at the crown of the fork, in which case, fixing it properly would be more expensive than replacing the fork.
It’s steel, and the bend doesn’t look too extreme so you can probably bend it back. I would still inspect both the frame and fork for cracks, and check the head tube with a caliper for roundness.
i know i’ll get downvoted into oblivion but i’d take the wheel out, slide the fork in between those bench boards for leverage and straighten it out, put the wheel back on and ride on. it’s steel and i’ve ridden worse.
Steel is real! Bend her back and ride her!
New one. It’s not too expensive.
Sorry, the fork is done. You’ll need a new fork. A new fork and labor might be more than the bike is worth. Also, check the underside of the down tube right behind the head tube for cracks in the paint, deformation for impact, etc. since the frame might be a goner too. Sorry.
