1969 rear frame looop

Does this look like someone bent the rear frame loop on purpose? Its a V 1482 bike, the frame loop should be flat, correct? Hopefully the photo works.

Looks bent down and bent up.

That's what I thought, think I can heat it with a torch and straighten it back out? Or would it be easier to just purchase and install a new frame loop?

I like the bend.
Does you wife know that her 6 piece bake set is in the garage?     LOL

The bend pulls the rear fender up to an odd angle. She sure does, one of those wedding gifts that hasn't been used, ever...

[cbridgewater]

Any advice?

[thrownchain]

It's near impossible to get any tubing that's bent to bend it back at the same spot, if you do bend it back, (or try), what will you use as a gauge to know when you've achieved your goal?

[cbridgewater]

I was hoping to flip the frame upside down on a table, heat it, and flatten it. Pipe dream maybe.

Heating will change the temper of the metal.

It won't matter for supporting the rear fender, lol. Mike

A new rear frame loop is probably less than $100.00, "character" is priceless...

I take you you guys think I should leave it as is?

I would straighten it, like it is supposed to be with heat as opposed to a new rear loop if it was my bike. Easy to do with a helper.

Now your fender will fit and it doesn't have to be perfect to look right. The rear loop on this bike was worse than yours.

Any suggested method to straightening it?

First you need a torch capable of getting things red hot. Start with the two rear most bends, get them red hot, then you could use a 2 x 4 maybe 6' long, put it over the rear of the loop and under what ever it will reach up front and bend down till straight. A helper really helps.

Keep working those bends side to side as needed till they are straight. When you are happy with those move forward to the next bends, put your 2 x 4 under the loop and over the tire, heat the bent area till red and pull up till straight.

With a good torch and a helper this is really very easy to fix, 1 hour tops.

You can do it, you just need a torch and a friend. It's already bent,you are not going to hurt it.
