Jord Posted October 16, 2019 Share Posted October 16, 2019 I’ve got rust along the weld on chain side of swing arm. My bike is a 2016 so out or warranty. Has anybody got any advice on the best way to treat/remove the rust? Link to comment Share on other sites More sharing options...
Global Moderator sorkyah Posted October 16, 2019 Global Moderator Share Posted October 16, 2019 Surface rust? Or like salt/corrosion rust ATGATT... ATTATT, two acronyms I live by. Link to comment Share on other sites More sharing options...
Jord Posted October 16, 2019 Author Share Posted October 16, 2019 surface rust, it looks like slight bubbling of the paint along the weld, in places the paint has flaked off. It’s not major but it annoys me. Link to comment Share on other sites More sharing options...
mossrider Posted October 17, 2019 Share Posted October 17, 2019 Lightly steel wool it off and coat with wd-40 if it's not too bad. Wire brush it clean and truck bed black it if it still bugs you. Bead blast it the whole swingarm and powder coat are always an opton. 1 Link to comment Share on other sites More sharing options...
Jord Posted October 17, 2019 Author Share Posted October 17, 2019 Thanks for the advice, I think il try to steel wool it then find the closest match touch up paint and seal it. I have thought about powder coating. I can’t see any problem removing the swing arm myself but I don’t have the tools to remove and replace the bearings, and I’m assuming the bearings would have to be removed before powder coating Link to comment Share on other sites More sharing options...
kylerhsm Posted October 17, 2019 Share Posted October 17, 2019 This has happened to my 2017 as well. It's a testament to Yamaha's cheap ass build quality. If you research the issue, it's actually quite common and those who managed to get in before their warranty expired ended up getting their whole swimgarm replaced I scrubbed the rust back on mine and touched up the paint. Mine occurred on the brake side of the swingarm along the weld. I'm restoring a 1988 Honda Bros 400 at the moment and the quality difference between the two bikes is nothing short of astounding. The Bros shock has needle bearings for one, and the bolts looked brand new after pulling them out without even cleaning them. Oh, and the shifter linkage has rubber seals to keep the grease in. I just regreased the shifter pivot on my MT07 yesterday and the grease (or lack there of) is "retained" by two metal washer. Cheaaaappppppppp. Anyway, rant over. The MT07 is still my favourite of all the bikes I've owned, but they definitely don't make them like they used to. 1 1 Link to comment Share on other sites More sharing options...

Jord Posted October 17, 2019 Author Share Posted October 17, 2019 Yeh I only got the bike on Saturday, I somehow missed the rust when I went to see and test ride the bike, I have got a 3 month warranty from the dealer but I really can’t see them wanting to do anything about surface rust to be honest Link to comment Share on other sites More sharing options...

Beemer Posted October 17, 2019 Share Posted October 17, 2019 Have you tried you tube for videos on that? I'm sure they have plenty of them. You can easily sand that stuff off and spot paint it to where it's hardly noticeable, if at all if you do it right. Beemer Link to comment Share on other sites More sharing options...

I don't think the quality of this one bike is a good example of all of Yamahas bikes simply because it was intended to be a bargain bike with cheap parts and build but yeah, gotta love it anyway with that amazing engine at a bargain price.

robbo10 Posted October 17, 2019 Share Posted October 17, 2019 I would give the dealer a chance to put this right. Either through his own warranty or by special application to Yamaha. They replaced rusty ones in the early days (as said). Must be worth a try? Just do it! Link to comment Share on other sites More sharing options...
1tondriver Posted October 17, 2019 Share Posted October 17, 2019 Mine had the some rust and I just sanded it down a bit and hit it with some Rust-Oleum and good enough. I doubt it will ever rust through before I am done with it. Should it happen? No, but not a huge deal to me. 1 Link to comment Share on other sites More sharing options...
Premium Member noodles Posted October 17, 2019 Premium Member Share Posted October 17, 2019 Likewise I have bare metal and some rust showing under my chain guide, eventually I was gonna sand away what I could and just rattle can paint it black. No big deal but annoying his face seems pulled and tenselike he's riding on a motorbike in the strongest winds Link to comment Share on other sites More sharing options...
ElGonzales Posted October 17, 2019 Share Posted October 17, 2019 Thick grease between the rubber chain guide and swing arm two times a year as an temporary first aid (...for years ). New coating if you have to remove the swing arm anyway because of worn out bearings or something else. Or spot repair if the chain is removed. If somebody want to powdercoat (like me someday): there is a big rubber block inside the swingarm, chain side Link to comment Share on other sites More sharing options...
Slono Posted October 18, 2019 Share Posted October 18, 2019 (edited) I saw this thread and decided to check the swing arm on my new-to-me 2018 MT-07. Sure enough the facking thing has rust on it with not even 5000 miles on the odometer. It’s actually pretty disappointing seeing as how my outgoing 2017 SV650 is really well built for around the same price point (slightly less actually).

Jord Posted October 18, 2019 Author Share Posted October 18, 2019 Thanks all for the reply’s. I know I should probably take it back to the dealer but it’s over an hour drive/ride away and I really doubt they will be of much help. Ive purchased some hammerite satin black which says on the tin can be applied straight to rust. My plan is to wire wool it than touch up. I will post some before and after pics when I get around to doing it Link to comment Share on other sites More sharing options...

If you're going to prep the paint, you may as well apply some POR 15 to it to neutralize the rust chemically before painting over top.

poida Posted October 19, 2019 Share Posted October 19, 2019 got rust at various sections of the swingarm, massive patch under the rubber chainguide which is disappointing. paint is so thin... what touchup/color is everyone using? 1 Link to comment Share on other sites More sharing options...

poida Posted November 10, 2019 Share Posted November 10, 2019 i applied a coat of the tectyl rust prevention, apparently its up to 5 yrs protection. Seems to be ok so far and its a wax like coating. Link to comment Share on other sites More sharing options...
mossrider Posted November 10, 2019 Share Posted November 10, 2019 I used a Sharpie. Sad, but the ink is better than the paint. 1 Link to comment Share on other sites More sharing options...
Q_mass Posted November 14, 2019 Share Posted November 14, 2019 (edited) I had rust appearing on my swingarm, it was just where the rear suspension is connected to the swingarm. The paint came off due to small stone chipping. I covered it with HAMMERITE Stone Chip Shield. Since then, it seems allright. Where the swingarm is made out of steel, it will always start rusting when it's not protected. I found this company that make custom aluminium swingarms (http://metmachex.net/swingarm-prices/) I have sent them an email a while ago but didn't hear from them... I don't think they are producing anything anymore, or they're just too lazy to check their email. However, I believe if you would swap old MT swingarm into this aluminium masterpiece, the value of the bike would go up.
