Jet Fighters and Nuclear facilities compared to Motorcycles = Apples and Oranges and why? Because Jet Fighters and I am sure certain parts in a Nuke Plant usually have safety wires includes into the bolt and nut. You do not often see that on street motorcycles much especially something like a Bonnie and especially something like a foot peg.

I think you missed my point Chuck. Without actually knowing the facts about testing and failure, I don't think anyone is qualified to simply dismiss the problem. My death from a motorcycle accident would be just as real to me if I fell off my Bonneville or if I was in a plane crash.

At least you get to inspect the bike. You don't get to inspect the plane.

Well that's very true. There are lots of parts on planes and these bikes that could fail under certain conditions but some more likely than others. For example, a head bolt could pop, or the bolt holding the handlebars on could break - things that are unexpected and not part of routine maintenance and inspection. I'm sure there are lots of Bonneville owners out there that don't have a torque wrench and, even if they did, wouldn't use it on a routine inspection of their bike before going on a ride. Especially since Triumph doesn't suggest that you do so.

I haven't come to any conclusion about where the problem lies here but based on what has been presented in this thread, there is a problem for some riders.

I think this has been a good discussion to raise awareness of a potential failure, for riders, and hopefully for Triumph. The least Triumph could do now is include a check on the torque of of these bolts as part of the regular maintenance.

Truth.

Here in lies the BIG problem, most of the people that ride these bikes will NEVER read these forums or perhaps these threads. Therefore THEY will NOT tighten their foot peg bolts. What about them ?

Quoted for truth.

Well, actually there have been opinions from a couple technical guys who, last I read, agreed that one should make sure the pegs are tight and just ride the bike. That would be rbneil and norton.

And there's me. I do failure analysis for a living...only on serious stuff like Jet Fighters and Nuclear facilities. I told you all there was no design flaw 5-6 months ago. There isn't. You have no valid evidence of design failures...instead what is clear is that there are a lot of loose pedal mounts.

One last time...everyone here go tighten your foot peg mounts, give it your best estimate on the side where you can't get a torque wrench. Wait 3 months and do it again. 1) you'll find that after 3 months they are still tight and 2) you'll notice no new failures have taken place.

Tighten your pegs...enjoy your bikes!

Peace
John

I have fifty some odd years in serious mechanical trades and I agree with you completely John. For those that can't duplicate the torque after just using a torque wrench to get the feel on the easy side-- they shouldn't be swinging wrench at all.

Wow maybe those knuckle busters who forgot how it is to just start out learning how to work on their bikes should take up knitting.

Just saying.

/sarcasm off.

Strangely enough this morning I had a nice ride on a friend's new Honda CBF600 Hornet and the first thing I did was to examine the footpeg fixings closely. My friend was a bit nonplussed about that and asked what was I looking at. I explained excitedly with some pleasure that his footpegs were mounted on fixed clevis brackets...

I think he believes I've flipped or suffer from dementia or something. All those lovely technical features on his new bike and I concentrated on his footpegs...

Good comments Forchetto! I find myself eyeballing the way other bikes have their footpegs designed...funny what snapping a footpeg off does to you! Have a Merry Christmas!
