Hi All
Me 71TR6R has slightly bent footrests, more on the right than the left. Cant't see any sign of any other damage apart from a slight scratch on the RH exhaust so presume its fell of its stand or a very low speed tumble.

Is it possible to just use brute force to bend them back, cant be 100% sure but the RH bracket looks to be bent in a fraction so dont want to damage the frame eek

I bent my right footrest after an accident last year.
I took it off the frame. heated the bent part cherry red with a welding flame (acytelene / oxygen) and kept the undammaged part cool with wet rags.
A few taps with a hammer end bending action wit a large shift spanner did the job.

Do not cool the hot part in water after you are finnished. Just let it cool gently to the air.

It's possible to use brute force, yes. I successfully bent my timing side peg back and down using a five foot section of pipe slipped over the footrest and an extra pair of eyes to watch the frame plate.....slow and steady pressure did the job.

I chalk that up to me and a friend "catching" the bike when it started to go over a few years back...he thought I had it, I thought he had it, never dropped completely...long story short: the footrest does NOT make a good side stand!! shocked

I'd rather cold bend it than use heat.....would probably lose some strength after heating and cooling....

If you're unsure about bending the frame, you could always chuck the footrest up in a vise and use the pipe there.....

Several years ago, I had a low side tumble that bent the drive side footrest straight up. I was about 70 miles from home and just stood the bike up and jumped up and down on it till it straightened out. Took it off when I got home, put it in a vice and ball peen hammered it back to the correct angle. It's still on the bike. Greg

I spent a truly unforgettable and illuminating afternoon covered in grease outside Raber's in San Jose trying to fix a million things. When the shop closed, the owner and some high-ups came out and lovingly hazed me about the bent footpegs. In their view, and you knew they had been debating it for years, you leave it on the bike and bend it cold with a disused fork tube.

Mr. Raber kept telling me, "C'mon, act like you like this thing!"

IME Marine Engineers know about such things, particularly when they are familiar with the part.

My problem was: the part that was bent in my footrest was bent in a light S-shape, so what I did was the only way. See that the upward part went down and than the downward part went up again. In marine engineers school we were teached blacksmith work - Yes, I know, but it was in the 1960's and now they learn how to program a fuel ecomomy computer - but I remembered part heating and part cooling works well when you need to bend a short part in a longer part.
The blacksmith teacher (who must be in his 90-s now if he is still alive) serviced horses hoofs (is that English?) in his spare time. He spoke limited Dutch and fluent Frisian and believe me: when I ride my bike through Friesland I still think about this craftsman.

Hi,

my timing side footrest has been bent slightly too, when I got the bike. I dismounted both footrests because they were interchanged (left to right) as well. I clamped the bent footrest into a vice and gave it some fair beats with hammer and black paint - ready.
