Broken footpeg - anyone else?
on: May 24, 2020, 01:35:00 AM
My right footpeg broke today while taking the bike off the centerstand. I often stand on the pegs with the bike on the centerstand and then rock forward and ride away. When I did that after leaving the gas pump, the right footpeg sheared off. It's something that I've done a hundred times before, and I only weigh 150 pounds, so I guess it's stress fatigue? Has this happened to any of you?

No. Yikes. Were you landing a jump?

Ok. Read your caption now. I've wondered if I should replace mine because they are skewed due to pin and peg hole wear. Did you lose control of the bike for a bit? This kind of failure would happen at the worst moment; up on pegs to manage a rough patch, crossing RR tracks, etc.

No loss of control, because I was in 1st gear and on level pavement. I didn't know exactly what happened for a bit, and I kept paddling my right foot in an attempt to find the footpeg that wasn't there. Fortunately, I was only one mile from home and could just rest my foot on the exhaust shroud until i got home.

Had the bike been dropped or has the foot peg struck something.  Maybe a stress fracture from a previous incident.   :187:

Either my eyes are failing me or you have another bracket there to what I have.
Have you an intermediate bracket in there to lower your standard foot peg position?
One that uses a bolt through the standard foot peg ? As opposed to a pivot bolt and a split pin ?

Have you drilled the hole bigger in the footpeg to fit those peg lowering brackets ?

There is something strange on this picture - you footpeg is attached with threaded bolt instead of OEM pin? I'm sure this is the reason of footpeg breakage - footpeg hole is supported by threaded part of the bolt. The thread fillets acts as crack initiators - they leave marks on soft aluminium and lead to stress concentrations in a hole.

I mean - you can use threaded bolts for this purpose but the threaded part mustn't contact with holes in footpeg and mountings. If the same bolt is used on other footpeg I would suggest you to replace it too preventively - probably it has cracks.

And once replaced both footpegs use bolts that has enough non threaded section - thread should never be in contact with the hole.
