So I think it's a Hercules made Hercules, before Raleigh took them all over in 1960. You can ride ok with the forks bent on that bike. If the bend was at the crown I would recommend checking for cracks, but yours is bent along the forks, someone probably bumped into something. The bend that should be there is near the bottom of the forks where they curve forward. If you follow a line along the head tube down the forks, it should be straight until the bend near the bottom. It will steer better when they are straight. Your front wheel should be about and inch or two more forward. But it will ride just like it is. Some will say you can turn the wheel backwards and run the bike into something to bend it back, but I wouldn't do that, it should be done very gently with a vise or other method. If you do take the forks off, remember the bearings are loose and will go all over the place. Same goes for the crank bearings, they are loose. If I remember correctly, there are 22 bearings in each headset cup and 12 in each crank bearing cup. I loosen that type over a bucket to catch all the bearings, then use grease to hold them in place when I put them back together.
