Buck,
I had them, they had too much overrun and I had brake issues . . . Get EBC if you don't want something expensive, the new V line has the carriers painted so you can choose your colour

If I buy em it'll be out of curiosity. These aren't the same rotors that have been discussed already

Anodized, not painted. [roll]
Also, if I buy them, I'll check the runout and the gage and if they're not up to par have them replaced. Braketech is the only company that deserves a premium price for rotors imo.

You're wrong, these are the first FULL FLOATING China rotors I've ever seen. ;)
I'm off to the official Ban Yourself thread
;D
By the way, they do look like a sweet deal

IMHO, you're going to spend some money getting better performance than these, with the right pads.

They did not used to be full floaters until someone in the Chinese factory realized that with a socket and a hammer they could turn their semi floaters into full floaters. ;D
I just don't like putting china stuff on my Duc. Call me a snob but I would rather ride a stock full Italian Duc than do mods from China.
My buddy put some of those Ebay 3/4 levers on his FZ1, they rattle about. Just don't see myself ever intentionally putting a china made part on my sweet little Duc.

Personal choice/preference is always your privilege. I just suggest that a blanket condemnation of Chinese goods is not justified. True, there are some sub par items from China in all categories of mdse. However, there are also a multitude of quality parts and components coming from there which are used by many companies in a broad spectrum of products. It would not surprise me if there isn't a few Chinese components in our bikes. Maybe a bearing, or an ECU detail component.
I also think that a lot of the ebay Chinese motorcycle parts can be cheesy. But they are improved from offerings 2 or 3 years ago. One example which comes to mind is turn signals. Most of them are junk, but I recently looked at a Chinese pair which put my Rizomas to shame.
As for brake rotors, I have another bike with YaniShinka rotors. Many forums have posts from members describing them as junk. They obviously just want to post to give the impression they know what they are talking about when the opposite is true.
Getting too wordy, but another example of Chinese quality is in the world of metal working machines and associated tooling. Some of the highest quality CNC machines are Chinese and are used to manufacture other machines. But, as is the nature of their manufacturing, they also offer marginal machines. As for tooling, I can buy new end mills from China much cheaper than having them resharpened. For all intent and purpose, they are the same quality as U.S.
I suggest instead of a blanket condemnation that a buyer beware attitude would be more fitting.
Yep ^.
I personally don't care about which side of an imaginary line my parts are manufactured. Not an accurate way to guage quality or value imho.

Yep, the snowflakes used on the superbikes at a great price. They are semi floaters, not full, but a hammer can fix that. If interested, jump on it, Fred constantly runs out. Got the black version of them on my bike.
An hour after you put them on, you'll just want some more.

Hello ladies and germs.
So for $175 I was too curious to not try out a pair. Took less than a week to arrive via DHL express. My initial impressions were positive because of the fast shipping, thoughtful packing, and out of the box the machining quality seemed good and the carriers were perfectly smooth and perfectly anodized;
(http://i1008.photobucket.com/albums/af202/johnnyblaze19761/20140519_102325_zps48sgyzs3.jpg)
However, I am a bit disappointed on 2 fronts: for starters, the weight; 3.13 LBS each. I was hoping for a significant reduction over the OE snowflakes.
(http://i1008.photobucket.com/albums/af202/johnnyblaze19761/20140519_102125_zpstpjajmpe.jpg)
The second thing is, and if this is the case then I will be filing a complaint with Paypal/eBay; they do not appear to be "full floating" as advertised. There is very little play in the buttons, in fact no radial play at all, any movement (just gentle tugging, no forcing) is side to side as in parallel to the rotor and wheel, rather than along radius of the rotor. Also, I see these wavey circlip/washers here; from what I understand that is only found on a semi floater, the wave is what prevents the movement, yes? no?
Backside of the rotor showing the buttons:

Other things to note; the thickness is 5.67, and although I do not own a dial indicator this spec is true and exact along 18 points. I will certainly check the runout properly if I choose to keep these.
Hmm, it appears they are full floating there just isn't as much play as I expected. Of course this could change once they are mounted obviously. The Brembo's have flat circlips and are rock solid with no movement at all.
They are semi floating, the wave washers are springs, just not as heavy as on the Brembos. Full floating has no springs. I wouldn't worry about it, it looks like those springs barely enough to keep them from rattling. You should only have axial play. I think you did well.
I've continued to dick around with em', and they actually have more movement than I realized. When I grasp the rotor by the carrier, and briskly fan them side to side there is a considerable amount of movement. Not sure how I'd go about measuring the precise amount of movement but I'm guessing at least a mm or so. Cursory search of the webz show several Jap bike forums discussing the "wave" washers/springs on their "full" floating rotors. It seems there is some ambiguity in regards to the exact differences between "full" and "semi"....but from my understanding (layman terms) a "semi" floater has barely any discernible play at all. The "semi" floating Brembos I have in front of me (one pair from an 01 M750, another from an 06 M620) are rock solid.
I really like the quality of these just as far as my sense of touch and sight go. The machine marks are consistent and precise, the coating on the edges and the carrier is deep, and the carriers themselves appear to be machined/stamped to a very high quality, better than my OE set. I've been wanting to buy a dial indicator for a minute now, this will be a good excuse to do that.
Ditto wot Howie said.
If as close to full floating is what you have to have, there are several threads discussing how to flatten the wave washer springs. Basically, you support the disc and carrier and then beat down the springs with a scientifically sized socket. ;D
I suggest running them as is until the pads are bedded to them and then put the front on a stand and spin the wheel to verify if there is anything to be gained. No dial indicator, just observe how close to freewheeling it is. I have done this several times and have always been satisfied with the semis. Of course, this meant that I lost one bragging point. ;)
Mfrs in the PRC can make great stuff if they want to.
I've seen terrible quality and also great quality, it's just finding the right mfr.
Just curious, how fast do you ride? Are you having problems with brake fade or disc warpage?

I'm pretty slow actually. By fade do you mean the lever going soft? that has happened only once in a panic situation and my wife was on the back...not good [thumbsdown]. I assumed it was old fluid or air, replaced the fluid and bled the lines after that. My current brakes have been ok, and beyond that one time I have never experienced fade. I don't care for the slight pulsing and I feel the power could come on a bit faster, but I believe the new master will solve that. If I was riding hard enough to be having serious issues with fade I would have ponied up the extra cash for something that is a proven upgrade over OE. The feedback on these amongst other forums has been so positive that I'm expecting them to be at least as good as OE, and treating anything better as a bonus. That and I'm obsessed with inexpensive products from CN...one of my best selling rotary tattoo machines is CN made, and it outperforms and outsells Stigma and Hyper rotaries that cost $5-600 more. So I'm a bit fascinated any time I see something like this and have to try it.
