So since so many of you are expert welders, let's see what your stuff looks like?

REGARDLESS if it passes an X-ray, the entire point of a thread like this is the welds look like dog shit. Guarantee you a boroscope can see a micro undercut on that blob of shit on the front gusset...

Very true, and like you said and I agree with the first part of a weld QC process is the visual inspection, being that these are all class A visible surfaces you would think they would be like lets get ole boy who programmed the robot or manually shit these welds on a drug test. Also others liked to throw around about X-ray, gaurantee they dont do that, I have never seen any production facility use X-Ray. I have seen Ultra sound, but like X-Ray it is a reference tool to show discontinuities within the weld, the real test would cross section and etch it under a microscope to look for microcracks or other defects, most of the time you can see the pororsities via UT or X-ray, and definitely cross sectioning. Either way I am not in dirtbike industry so I am sure you and I have zero credibility on this topic. Lol

Not for nothing, it's all fine to be cynical about it, but Yamaha has been having frames crack along welds, and there are probably quite a few successful people in a number of fields that post here.

I'd doubt very much being part of a MX team or a pro rider is a definition of doing "it", whatever that is, right.

You would be shocked sometimes what some spec out. Most engineers dont have any welding knowledge or background.

Exactly, if yami didnt have any issues with crack welds. No one would question the look of the welds

I have an aluminum YZ250 with over 200 hours. Hasn't broke yet, probably built with the same robot. Maybe mr. robot is getting older and more complacent?

So now that the machine is thinner, lighter, has electric start and apparently more feel in corners, the bugaboo is the look of the welds.

Some of you just don't like Yamahas for whatever reason and want to pick them apart. That's fine, but just be up front about it. Admit it, and then just don't buy one.

Why don't you all wait until the bike has been out for a few months and find out if the frame holds up. If it doesnt, come back and have Yamaha hate-fest 3. They have improved everything everyone wanted improved, but now the welds look icky.

Yes, much ty

Yeah but did you X-Ray your frame to look for micro-cracks? Tongue

I have Yamaha and KTM and are precisely the two brands that more chassis have broken in recent years. Luckily mine have not broken, but it's scary.

An well, my YZF is 2006, I think is more broken in 2012 to 2014

And the KTM is enduro EXC 2 Strokes but some times I do MX and I think the problem is in the MX models around 2017, 16 and,,,and 4 Strokes



I hope the new bikes don´t broke.

I'm willing to bet both of those broken bikes have little to nothing to do with inferior welds. Aftermarket triple clamps, improperly torqued nut, dynamic of the crash. A picture alone does not tell a story. That should be the lesson of this thread, but something tells me that won't be the case.

Probably, but Yamaha did have an issue with their last gen frames right up by the steering stem. Those welds "looked" fine but there were plenty of instances of the actual weld cracking down the center.

How about this, not a welder, but if your weld or any type of joint is exposed to view it should be clean and smooth. If thise were on the motor side its one thing, but really?? And once again, i'm not anti Yamaha

Aeffertz, yes the weld did fail, as any aluminum welded component will more then likely fail in the weld because the weld is way weaker then the parent material. Doesnt mean the weld is a bad weld, just that fatigue or joint stress caused it to fail.

Sorry Harry bro. I don't hate Yamah, I'll admit I'm not a fan of Honda. But hell if Honda builds a good bike I'll admit it.

Yamaha welds have been poor for awhile now, and it's pretty pathetic. It's not just ugly, it's a safety concern.

I'll buy another Yamaha when they build a modern 125. Tongue
