The Subject is only 60 days old
The damage. Looks a lot worse in person.
Even the decal is starting to rust.
What should I do about the rust. Obviously the parts they use are not stainless. So what should I do? Take it back to the shop and ask them to replace the parts with faulty ones again or talk to Yamaha. I need your advice please. Thank you!
Hi, I have the same bike, but bought it around 4 months ago.
I have noticed the same problem but yours is alot worse than mine. I tend to wash my bike about once a month and run some wax type protectant over it, so that probably has held back the rust a bit. But mine lives in an underground carpark and hasn’t had much rain use…so…
I agree it is slack, even if it is just decorative pieces.
I would take it back, and get them to replace the bits, should be no hassle, but I can’t imagine the replacement bits will be any better.
Maybe it’s the ‘acid rain’ here? I always feel like a dick complaining about things like that when you look at all the beat up scooters around, but hey, Vino 125s are not cheap.
Keep us posted. Maybe I should do the same?
With 160km on the clock!
I used to get a lot of chrome work done.
They can go quick and nasty or multiple layers with copper or nickel underneath.
Yours. The first.
Only way to fix this I suspect is for you to go to a reputable??? chromer and have the job done properly and just pay.
Otherwise you will probably get another 60 days worth of shiny new chrome.
Complain anyway and get a new set. Then maybe if you keep the old you can get it redone.
What material is this supposed to be - steel? Stainless steel doesn’t mean it doesn’t stain at all actually - there are different grades and some will actually show signs of surface rost which is not a problem from a mechanical point of view but of course not nice to look at (and shouldn’t happen to a bike that is only 60 days old).
Since this might be a general problem with the product I would contact Yamaha directly and see what they have to say about this.
My company also had some products delivered that turned out to be of a different material partially since the maker of that part cheated, they used an inferior metal. Ironically that part was made in Taiwan (the assembled product came from Europe).
Just as Plasmatron has said numerous times – cheap crap for the Taiwan market.
My Yamaha motorbike was made in Japan and is around 5 years old now. The original chrome is still in top condition (bike lives outside), but the replacement wing mirrors are Taiwan-made and are totally corroded after less than a year. Same goes for the chrome-plated engine protector thing – it actually rotted all the way through after about a year.
Cheap crap for the Taiwan market.
For many years I had one Yamaha SR150. When it finally collapsed I got another one, exactly the same type of model because the first one had been very good except for some chain problems. Well… that was about a year ago, and within a few months my “new” bike looked as old as the first one. Now it looks older/rustier. Both bikes were made in Taiwan, but the older one was definately a better built bike. Both were made in Taiwan. Actually I think the first one was not badly made except perhaps for the chain. Wish I could say the same about the current Yamaha.
My locally made Ford car has the same problem with some badges but at least it seems to be restricted to the badges. The car is only 4 months old though.
You only made one mistake-- you bought a scooter in Taiwan.
Smugness aside–bike covers can be bought at most large helmet stores. They seem to limit corrosion.
Ever consider painting all the shiny parts a nice flat black? Always seem to work on the fence posts back home on the farm–might even deter theives from theiving.
I have decided to take the bike back to the shop and see what they can do about the problem. I would like them to replace the parts ASAP or have them talk to Yamaha about it. In my opinion the bike should be corroding 60 days after purchase. The bike has been rarely as it only used for light riding as you can tell by the odometer. I have already ordered a Yamaha cover for it but it is parked in covered overhang. The chrome pieces really make the bike stand out and painting them flat black would really change the look of the bike. The pictures I took were right after I washed and waxed it. It is in pristene condition and I am quite upset about the quality of it. I hope that Yamaha can step up and rectify the problem.
It’s not even parked in the elements? Wow.
Yep, I’d be back to Yamaha in a hurry, especially after 2 months. I don’t know what they could do other than replace the parts in question so they can rust after 4months/320km 
Tried any rust preventive maintenance? I know, messy and impractical for a scooter. It’s funny that the mirrors are the same insta-rust pieces of junk that are on my RZX…I polished, waxed, sprayed WD-40, even covered the mirror stalks in grease…Nothing worked. I’m reluctant to tell you what those mirrors are going to look like in six months.
I think your only solution is to have the pieces re-chromed by a competent private party. Or you could ask Yamaha to provide you a set of replacement parts for the life of your scooter… 
Back to what one said about crap for the Taiwan market: is it possible to buy the Japanese models here? I’m glad I bought a tacky plastic clad Yamaha 風光 125 recently, instead of the much classier looking Vino. Man, I’d be pissed right now with the rust problems.
I have run a waxy rag over it once a month and mine looks OK, but I think it would look bad if I didn’t do that. Most of the chrome except the handle bars is actually plastic that has been chromed. So far no problems with that.
Having worked with metals a fair bit, I’ve found it is a good idea to regulalry wipe surfaces down no matter what quality they are. If oxidation layers are left, it doen’t take long to start corroding, even aluminium doesn’t last long around here - I think the cleanliness of the air doesn’t help.
I just saw this problem. I used to live near the Yamaha factory in HuKou, HsinChu, County. I would consider going to the factory. Some high level folks work there. Explain the problem and ask for help. The people I met there were pretty good about helping with any Yamaha problems I had. If you don’t get satisfation the first time around, consider putting a sign on the back of the bike, in Chinese, that says something to the effect “This motorscooter is rusting after 100 km” If the name “Yamaha” isn’t clear and apparant, make it so but don’t put it in the sign. Just make sure it’s visible on the bike. Then go back and ask a manager to look at your bike without pointing out the sign. This should work quickly and efficiently.
Take Highway No. 1 south to Yangmei. Keep going on No. 1. If you see a lumber yard (big one) on the right about 10 k past Yang Mei turn right. This will take you into town. If not, go to a “Y” and take a right and double back about 3 k. In any event, when you get into town, find the train station. Go North or back toward Taipei on the same road that is in front of the train station. You will ride along the train tracks and will see the Yamaha factory on your left. The road to the left just past the factory will get you there. Good luck.
