Are they really as crap as some people say?

Why would a company like Yamaha stake it's reputation on shoddy builds? Surely the quality control in these Chinese plants would be carried out by Japs who are under strict orders to keep things tickedy-boo.

I'm interested to gather some opinions on this from people in the know.

Ta in advance.

No they aren't. They are built with Japanese quality control and have the Yamaha network behind them.

The almost identical machines that come out of that factory with a Chinese badge don't.

From what I seen
Quite well built certainly much better than the Chinese makes I seen
Yamaha quality control Yamaha back up

Don't know about Yamaha but Honda have been building bike in 30+ countries world wide since the 1980's all appear to be very similar reliability wise

in my view the Main issue with Chinese makes is often the Importers no back up no data no easy source of parts

Powerful lot of speculation about this issue.

Have we got any informed, evidential basis for believing that they're actually made from different frames and parts?

Fuel injection versus carb, and I believe they have a different bearing on one of the wheels. What else can we show is actually different? [UPDATE - front brake, see below]

"Quality control" means rejecting shoddy parts and shoddy assembly. Conceivably there's a Japanese overseer - you may picture him as Toshiro Mifune if it helps - looking over every Chinese made frame and Chinese part as it comes into the assembly area and declaring "This verrrry strong, send to Yamaha line. This one lacks honour, fit only for Jianshe."

Reckon that's happening?

I had a Jianshe / AJS / Yamaha thing, and there was no problem with the build quality at all. Parts availability seems good (I only ever needed a clutch cable!)

But there does seem to be some cost cutting on components where they can. Wiring loom and connectors seem flimsy, the front disk brakes on the Jianshe are not as sharp as the YBR. Nothing major though. I'd get another one.

If the 'copy' is that good, I'm sure there are no real issues with Chinese Yamahas. Just remember, regardless of where they are built, they are built down to a price.

I knew that would stick a burr under your sporran Roger but I still stand with the Yamaha QC and the fact of the Yamaha network behind them.

I'm still not a Chinese bike afficiaonado, maybe one day. Wink

Just cos somethings built in China doesn't mean its got the bad aids
Many companies use the cheap labour of china for production
its the quality and standards used that matters.
Who remembers jap crap?
Of course there have been some cheap shit shockers but I reckon those were built to a price rather than a standard
and as western companies inject better standards, the quality will rise.
Your phones tablets and PC and many other devices were probably made in China.

You may still want avoid the self assembly Happy Kitty 50 for £499 OTR type bikes though

From the factory?

Why? Different callipers, different M/C, different pads, different lines?

I *think* it's a different caliper - the pads seem about twice the size - but don't hold me to it.

The way I see it Chinese factories can produce quality items.

Pretty sure they have ISO certified motorcycle factories there.

Why I pefer Yamaha 125s over Chinese brand 125s. Three reasons:

1. Because Yamaha has bigger market share in the UK hence it is better known, because it is better known it is scrutinsed and tested more.

For example Huoniao which is one of quality Chinese brands has sold only 853:

https://www.howmanyleft.co.uk/vehicle/huoniao_hn_125-8

Compared to more than 14 000 YBRs:

https://www.howmanyleft.co.uk/family/yamaha_ybr_125

AJS JS 125 has sold 600 only:

https://www.howmanyleft.co.uk/family/ajs_js_125

If you produce more the same thing longer time you do it better.

2. Sale preparation and service. The Chinese ones look to me as Russian roulette. You may be lucky or not. Not all guys buying can do that themself. You buy Yamaha and you do not need too be a mechanic they will do for you bike preparation and pre-sale service. You buy Chinese which may be brilliant bike, BUT the seller will hand it to you and the bike may fail because of say lack of enough oil or something simple as chain or brakes adjustment.

3. YBR is more expensive - the price reflects quality of work in it including more expensive materials.

Theoretically you may have cheaper product with better quality. In practice 125 market is so fierce and most manufacturer has already cut materials used to bare minimum. You go under this minimum only if you put lower quality cheaper materials. Like levers made of cheese for example Very Happy

I would love to see reliability statistics that can prove my assumptions. Unfortunately there is no one available yet.

We need to rely on common sense Laughing

If it seems too good to be true, it probably is...

Only if I can hold your hand and shake it. You look to be right. The calipers are both single pot knuckle-whiteners but they are noticeably distinct and the YBR one has larger pads.

This is exactly the sort of significant difference that we need to show in order to make a reasoned and reasonable comparison.

Is the difference between real YBR's and "fake" YBR longevity and reliability also due to the target market????

A Yamaha YBR is more likely to go to someone who looks after it, protects it with a cover and ACF50, changes the oil and takes it to be serviced at the dealer because it cost them a lot.

A rebranded bike (AJS etc) may go to someone who wants cheap transport and treats it as a disposable tool that is more convenient than the bus or an impoverished student or a clueless teen. Oil changes on an yearly basis and minimal maintenance will leave any vehicle knackered after a few years.

How many Million (or Billion) motorcycles have the Chinese built now, they must have some idea what works and sells?

From the yamaha ybr spares I bought for the AJS, I reckon the frame and engine casings are exactly the same, off the same production line. In fact, if I remember, the frame numbers are stamped the same, they are just sequentially different.
You could buy the ybr 4 clutch plate kit to fit the AJS.

The YBR150 big bore kit was a straight swap for the AJS. I wish I'd given it a go for the sake of £50.

The wiring loom, most of the switchgear, the brakes, the wheels, the carb. All different.

That was one thing that did annoy me at the time, AJS did not do a brake caliper servicing kit. Very annoying.

I can't remember exactly, but I think I did 17k miles (a lot at 10k rpm) and dropped the bike at 15-20mph once.
I think the only thing that went wrong in 3 years was the flasher relay.....but on reflection, it may have been a bulb about to go because I think I did have to replace an indicator bulb a little while later.
Anyway, whatever, I spent many weekends doing 250 miles in a day on it and it never broke down.
As far as I know (I sometimes pass his house), the lad who bought it is still using it.

I thought it meant checking that parts were within certain tolerances, which on it's own doesn't mean shoddy.

As I understand it the Chinese copies have slightly wider tolerances which for a single part may have little effect but in conjunction with the next part which also has wider tolerances, it can end up with a shoddy machine. Equally it could all be OK as the -0.05 on one part could work better with the +0.05 part next to it.
So it could all come down to Luck......

The same network and QC that their jap built bikes munch liners and transmissions?

The salient question is: what do you do if they aren't?

I suspect that's the difference. A line which prides itself on no defects, versus a line that's chasing some "spit out a bike every 90 seconds" target.

Everyone pays lip service to quality, but without seeing what's actually going on, all we've got to go on is owner reports.

My guess is that the parts (engine or whatever) come from Chinese manufacturers and the quality control put them in 3 baskets, one being 'Yam' tolerance, one being 'local bike' tolerance and the last being 'NFU' and sent back as scrap.

They love the idea of selling their 'local' bike for overseas currency but they sell the vast majority of their 'local' bikes in China and S.E.Asia.

You're probably correct, or at best they sell them on ebay china....
