Just saying.

/sarcasm off.
Exactly, nobody should be expected to have 50 years experience to maintain a motorcycle, or a car for that matter. These are production machines manufactured for the general public. Not jet fighters or nuclear submarines.

Yes, I am as big a pain in the ass in person as I seem to be on line.

Having worked in both the aerospace and auto industries I have some experience with the design and engineering philosophy of both.

The designs for aerospace are analyzed for every possible load case with very low margins of safety to maximize performance.

In the automotive world, analysis is performed with much higher margins of safety to allow for envinronmental, maintenance and aging issues that are not well known to the analyst. Every owner will have a different use profile. When you have thousands of users with different use profiles, there is no practical way to analyze for every one. So, the designs tend to be very robust to allow for unknowns. (The factor of safety is frequently refered to as an "ignorance factor").

I have done a cursory analysis of the foot peg design and found it to be satisfactory. That said, the footpeg cannot be expected to endure accidents without damage. It seems to me that the footpeg failures documented on this thread had a previous history of an accident or tip over.

The joint design used to attach the footpeg assembly is called a tension joint (discussed earlier in the thread). This joint is common in aerospace and has a long history of use. As I mentioned earlier, it is my opinion as an engineer that there is no cause for concern about the footpeg joint design.

Hello

Here in the eu they have been trying to ban home maintenance of vehicles for some time now, it keeps getting outvoted but they keep at it.
We do have the vehicle acceptance rules, which if taken too literally, will mean you cannot even change the colour and nil changes to the spec.

Back atcha. And you don't even have a modern Bonneville.

Personally I think Norton74 raises excellent points.

None of the concern being expressed means too much, without detailed statistics on numbers of failures, and cause of failure. And I have seen no evidence of any of that. The failures I have seen described have been after drops and crashes. Since I dropped my own bike this year, that makes me wary enough to replace the footpeg that side as a precaution, but that's about it.

Those of you who think the design is flawed need to get on to Triumph, but I bet they have hardly seen any returns for broken footpegs. If you tell them "I crashed my bike and the footpeg broke", I doubt if they will act on it.

Frankly, the whole thread has now become completely circular. That is some people think the design is fine, some don't, and Chuck seems intent on just stirring the pot to keep it going. Just my observation.

My advice for anyone concerned about the design of the footpegs is to replace them. There are lots of nice aftermarket options for that.

Before he did it, I'd have said it couldn't be done.

Can we close this thread then? I have been wanting to for some time as I think the title alone is missleading. Its just going around in circles.

I'll leave it open for a bit longer to see if anything more productive comes out of it.

I might not have a new Bonnie or a new bike but that does not mean I do not care about my Wind Brothers and Sisters no matter what they ride. That includes Electric Disability Mobility Scooters too.

All points are valid yes but after the end of the day are all points really profitable in the long run of the issue,especially if it keeps going in circles.

I agree on changing the Pegs if you have ANY doubt. Safety first and foremost.

That's your call. It's not violating the AUP, no one is really pissed at each other, it's just one of those things that keeps coming up.

No big deal. I'd leave it open for the time being, although 46 pages on the subject with no resolution or clear direction seems to suggest that it is about done.

A fair point, but the bulk of your recent posts seem to have been largely sarcasm, which generally speaking drive such threads off topic and into not very useful land.
