A couple months ago I took my not-so-new but new-to-me bike into a 'proper' Ducati dealership to have it looked at, as it turns out the previous owner didn't much care for it and it needed a full service. A few hundred pounds later and it rides so much better, but a few things had been pointed out to me that I couldn't justify paying for at the time.

One of these things is the rear brake pedal being bent. It's basically at a 90 degree angle upward. I'm still able to use it, and honestly hadn't even realised it was wrong (how unobservant Embarassed ) until it was pointed out.

Short of replacing the pedal ('cuz, monies) is there a way to bend it back into position? I'm worried doing so will weaken the metal. Do I need to bite the bullet and buy a replacement?

After sitting on a bike without a bent peg I realised how much safer it'd be to have a proper brake pedal where it belongs Embarassed Laughing

You could apply heat and straighten it but to be honest, if it's been bent that badly then the metal is already going to be pretty stressed.

Have you looked on eBay? Ducati spares come up fairly frequently on there.

I'd get a new or good condition used one. They're not expensive. Aside from that just heat it and bend it back with a hammer. I've done it before but only as a temp fix.

If you don't have (access to) a vise I wouldn't try bending it. If you try it whilst the lever is in situe you could damage something else.

What is it made of? Steel or aloy.

If you're not sure, a magnet will stick to a steel one.

It's probably bent because the bike has been dropped on it. I had a similar problem with a Tiger 955i and it turned out the pivot had also been distorted stopping the pedal from moving freely.

If it's an alloy pedal I wouldn't even think about bending it; steel would probably be OK. But as said, NOT on the bike.

If you hadn't even noticed and it's working perfectly fine then why mess with it?

I've bent an alloy pedal back, it wasn't difficult a little bit of heat a vise and a fork tube.

Embarassed Missed that bit, I'm blaming the 2 hours sleep I got last night and a lack of coffee.

I'll have a look when I get home whether a magnet sticks or not – I believe it's alloy but would be good to know for sure.

I had been contemplating replacing both brake and gear shift pedals with aftermarket parts, but I'm finding it surprisingly difficult to find bits Rolling Eyes

Thanks for the advice. I found a diagram of someone who replaced all the brake bits that left me feeling intimidated. Seeing as I've never done anything mechanical on a motorbike I'm debating whether it's a good idea to let this be my first thing..

Not sure if these are of any use?

If it is alloy, just replace it. It's tricksy stuff once it's been bent because metallurgy.

It CAN be straightened but it needs a huge amount of heat to make it pliastic (but not too much, a tad too much and you have a puddle) and also needs to be stress relieved after. There is a high risk it'll break in use unless this was done very well. I've done handlebar brake/clutch levers but not a rear brake lever.

A photo would help a bit with this if you could.


My girlfriend bent my shifter by standing and putting all of her weight on it, she couldn't get it to shift down -_-
It meant I couldn't shift down anymore as the shifter hit the frame, so only up, fun ride home!

In the end I didn't bend it back, I just undid the shifter and re put it on at a correct angle, might be something similar you could do on your bike, hard to tell without a photo.

Magnet test: didn't stick

I do have a photo but my iPad and Flickr aren't getting along so I'm unable to share it Mad

If this works to view, then yay

When you said bent I just thought you meant a little bent not full on just been in a car crash and now my legs are pointing the wrong way bent.

Yeah.... I have no idea how that happened.

When I bought the bike I noticed that there were scratches on either side of the bike, mostly on the engine guard and the handlebars - the clutch and brake levers have both been scraped (and I'd like to replace them as well..)

Having had it serviced I know the bike itself is in fine shape. It's just had some bumps and bruises along the way.

A decent second hand lever will probably run you £20-30 on eBay.

It's a pretty simple job that'll take a half hour at a very careful pace. The hardest bit is getting the spring bedded correctly. It can be a bit fiddly so you'll probably want to remove the entire hanger first.

Caveat: I've done this on the 695, not the 696, but they look very similar.

You have to be very careful bending ally as Stinky said. Also, I would usually bend it cold then if it snaps or starts to tear change it for another. The different alloys have huge variances in ductility and even moderate heat can alter the metallurgical properties significantly.

I have taken a piece of nice ally that turns well in the lathe, welded it then found that it can no longer be machined without looking like it's been worried by a dog with metal teeth.
