would be interesting to know what the sprocket bolts were torqued to.

Would PC or anodizing the swingarm have any effect on its strength?

Would presume with many of these older 2 strokes being purchased as project bikes and tricked out, then throwing someone fast ontop of it, that this type of thing could happen more in future?

I usually drill a couple speed holes in the bottom of my swing arms before I sell the bikes. Helps with resale.

much ty. How to spot a paid forum poster/artificial forum traffic producer (see list of actions/phrases below):
Copius pattern amounts of phrases like “Anyone have”..., “Anybody know?”.... and their variations.
Thoughts?
Any help is appreciated!
Thanks in advance!

Exactly. How many hours were on that RM? Metal fatigue can have disastrous results.

That's why I can't understand why guys think they can take a beat bike from Craigslist and make it "good as new". No matter what they do, it will never be good as new, you aren't reversing metal fatigue, especially in older steel frames. Cases, frames, swingarms, all of that will have a life span and as these bikes get older and older it's going to become a big problem.
Maybe, just maybe, some other manufacturers will pull their heads out and make me go into their dealership for a new bike once their old two strokes are totally used up.
Here's a fun fact, aluminum does not have a definite fatigue life. The fatigue life of steel is well known, but aluminum has a lot of unanswered questions still.

No doubt. Every part on a dirt bike will fatigue and wear out. A swing arm will fail at some point in its life cycle. Bummer, glad the rider was alright.

No. PC is done at 200*C max and anodizing only affacts a layer 20 microns thick of the raw material. Both treatments don't change the structural properties.
The questions is how many hours of hard riding was done with this swingarm.

Good luck with that, I had to replace a swingarm on a 07 rm build a couple of years ago. Took me months to track one down for that bike. If I remember correctly a new one was like 1200$ from Suzuki.

I don't know if you have ever seen him ride but that bike takes a beating for sure. He has been on that bike for quite a while now. Maybe 5 years? Who knows how many hours on that swingarm before the build.

Exactly, I went to etown almost every weekend this year, and he was there almost every Saturday throwing that thing around making it his B**** , and if he wasn’t at etown he was most likely at field of dreams doing the same thing. He is a fun person to watch on a two stroke that’s for sure

That's BS, the properties.of aluminum are well known, refer to Mil-handbook 5 and other sources of information. Do you think they'd use that material in aircraft if there still "unanswered questions"

After a lengthy investigation with a panel of scientists and engineers ,we have concluded the swing arm failure was caused by the swing arm decal .

We know how it behaves pretty well, yes, but it still does not have a fatigue life defined as well as steel does. I remember this because I had a professor in college who said he wouldn't become a pilot because of it. I'm not saying we don't have a pretty damn good grasp on it to the point where we can make things like airplanes, but it's not as well defined as steel's life cycle.

He’s had it for a long time. I think a few years so it’s definitely has a lot of wear. But I could be thinking of another 2 stroke he had before that one so I could
Be wrong

200c is 400f. Unless you can tell me which grade of aluminum swing arms are made of, and you know the guy who powder coated the swingarm you aren't discrediting what I said. "It can" =/= "it did" incase reading comprehension isn't your thing.

So one swingarm breaks and all of a sudden no one should ride old two strokes? Bros, you need to step back and drink a beer.
