Hi There, just wondering if anyone has observed corrosion at frame seam welds, particularly down behind footpeg mount area, see photos, my 2019 ATAS. Maybe the white paint highlights it more than black, where I may never have really noticed.
I checked closely, appears only paint peel, can't see weld cracks. I'm due for an unrelated wty repair, will enquire with dealer then. I'm just 'fact checking' with my AT colleagues before dealer says 'never seen that before'..... like they did when fork seals failed at 1500k's (1000k of that run in on tarmac). Credit where due they did wty replace though, including oil soaked brake pads

Haven't seen it on non-while models - yet.

Seems to be several instances on the Forum regarding white framed ATs, especially around the lower weld areas.

White paint in general is a challenging pigment in most applications, and not just on metal substrates. I am wondering if the weld area was not properly prepared prior to priming/enameling at Honda?

I have seen photos of rust on the black frames as well, but never to the extent, it seems to happen to the white frames.

Motorcycle News made an observation about the rust (and some shoddy bolts) in a 23 December 2020 article

There is also a thread on the issue here...
(8) bad rust on the frame | Honda Africa Twin Forum

I have seen some photos in other places as well, but yours may be among the worst I have seen.

Basicly Honda don't paint/weld the frames properly. See my thread from a few days after I bought my bike:

Hhmmm, welds not treat properly, there's history there, something about fuel tanks....🤔😏

Wow....that looks pretty bad.

My uneducated guess would be the white topcoat was applied directly to bare, untreated metal. Begs the question, just the welds or the entire frame ?

I would also guess as far as warranty goes, the only real way of doing an adequate job would be to strip the bike and either re-finish or replace the frame (even frame replacement wont eliminate the problem as it too will only do the same). I couldn't imagine that would be something to take lightly, either by the repairing dealer, or the owner.

I think myself, I would invest in a Dremel tool with a good selection of wire brush attachments, a good airbrush and suitable primers and topcoat paints and as these appear, locally treat before oxidation goes too far. Use of quality primers and paints and one should slowly get on top of most of these I would think, although there will be areas you simply cannot see.

Is this a widespread issue ?

The majority of cases that I have seen are from GB, AU, NZ. But probably any areas with coastal/marine and marine/industrial environments are going to have a higher rate of it.

I have not seen any evidence of corrosion on my wife's bike or my own, but Colorado we have a very dry climate :)

I wonder whether the actual location on the bike has anything to do with it.

Being in close proximity to the chain, foreign mater being ejected from the chain onto the frame at high speed acting like a sand blaster, compromising the paintwork enough so in these more harsher environments, the effects are being noticed more.

Correct me if I am wrong, but the photo's are all of lower areas of the frame where one would expect abrasion from grit filled water, rocks and sand to have an impact on painted areas.
Regardless, it still highlights inadequate frame passivation and/or painting.

Perhaps areas where moisture tends to sit for prolonged periods as well? Richard Newland in the MCN article I linked above states "I’ve mentioned the frame, too – and having a proper nose with a torch in hand has revealed more signs of rusty ingress (great porn name) in the nooks and crannies – which will only get worse with time. " He talks about the frame as well as the header pipes and exhaust. Richard Newland is also based in the UK, so I do think there is something to that environment that is not playing well with the paint.

well the most likely thing if you are talking about the UK is not really the coastal environment but the propensity to dose the roads with salt at every opportunity.
Having said that, it seems just as likely that it is variability in factory quality control. My graphite framed 2017 bike was just the same as the pictures above and really annoyed me. My current 2019 graphite framed bike is marvellous - no rust anywhere on the frame .... EXCEPT ... one large flange to the rhs of the downtube that is atrocious. Almost every bit of it displayed exactly the same appearance as the above photos - topcoat paint peeling off with apparently no primer. My thoughts are that when the frame was being assembled one part (the suspect flange) was either rusty when it was welded on, or had failed to go through some kind of steel treatment process. It's also possible that it had to be removed and replaced because of incorrect fitment, but if so the rewelding has been done very well. Anyway I did not want a dealer attempting to replace my frame, so bought some toothbrush style fine wire brushes and with those and my dremel I got most of the loose stuff off in about an hour. Painted with that phosphate stuff that turns rust blue, then used graphite hammered-finish hammerite. That was about 6 months ago and it still looks ok, but if I have to redo it every 6 months it's preferable to having the frame replaced. I don't know what I would do if the problem was in a lot of places on the frame, and I'm not sure how good a match the white hammerite is for the white framed bikes.

The white smooth hammerite is a good match for the white AT frame. I have used it on the underside around the centre stand area. Fixing stuff that should really be a warranty issue is often a lot less hassle .

and of course the centre stand itself loses its paint in no time. I once took my NC750 centre stand off and got it powder coated but apart from the well known chew of getting it on and off, taking it to and collecting it from powder coating shops is just too much bother. I have just used black hammerite on this one and it's OK

Thanks all for feedback. Paint flake is occurring on other side of frame behind RHS peg area as well. I first thought they were fracture cracks given the adjacent positions and stresses applied, especially from (minor) airtime off erosion mounds. I don't believe it's from stone spray, as paint flakes remain, not sand blasted. Whilst I live in coastal Brisbane Aust, I also don't believe it's environmental, I can say I've never experienced this on previous stable-mates including my 15yr old one (me) owner ktm enduro. I tend to agree with the notion of poor preparation. I also run high front fender, frame front holding up ok. There doesn't seem to be any other frame areas as yet presenting same condition. I'll present to dealer, see what they say, refer back to this forum. Might be matter of reactive then preventative maintenance, which I'm OK with just painting etc, just be glad my feet don't plough into the ground because pegs snap off 😅

Being as young as it is, it probably looks worse than it actually is. I'd imagine it would take considerable time to jeopardise structural integrity, but a good offensive plan is a good move.
Will be buying (potentially from Brisbane) in about 9 months, so I will be interested in the dearlerships response.
Best of luck !

Has anyone successfully had Honda acknowledge the frame rust issue ?
If so, what was their remedy ?
On my 2017 bike Hondas response was negative - cosmetic only. I didn't push it all that hard because I couldn;t see how they could fix it without a complete bike strip
