eBay brake rotors, seemed like a good idea at the time.
« on: July 15, 2019, 04:12:14 am »
Well I did the unthinkable, I took off without first removing my disk lock from the brake rotor.  After about 2 feet the bike came to an abrupt halt and proceeded to fall over throwing me off.  It came to rest on my right leg which is ok because I can heal the plastic can't.  I proceeded to stand up and upright the bike which is pretty heavy if I may say so even compared to me.  Red faced with embarrassment I surveyed the damage and was pleased to see there was none, that is until I continued on my merry way home.  The front brakes were unresponsive, I had to pump on them a few times for them to grab.  It happened every time I squeezed the front brakes.  I found that I bent the rotor and the fix is to replace them.

I was looking at EBC and Galfer brake rotors but starting at $250 each I looked for alternatives.  The only thing I could find were aftermarket rotors on eBay.  Most were listed as being in China and I would have to wait 2 weeks to get them.  I found a seller in CA which had them for $170, this included both sides and new brake pads.  Not everything from China is made with Crapisium so I decide to give them a shot.

They arrived quickly and went on without a hitch.  Below is a pic from the listing and a pic mounted on the bike.  I will keep everyone informed as to how they wear and if there is any difference from the OEM rotors since I searched the forum and didn't find much info on these brake rotors.

Well, having done the exact same thing before, I really do t think u bent the rotor from hitting ur disc lock.  My dis had a small mark from my full rotation and sudden stop.  And a broken foot brake lever bracket...And for u to have NO brake grab at all, unless u pump the lever, certainly isn't going to be from a warped/bent rotor.  Ur certain u havent cracked the caliper, or bent a fitting? Sure smacks as something else being the causation for lack of brake fluid pressure...imho

they look nice, but a couple questions;
are they the exact same outside diameter as the OEM ones were?
It looks like there is only pad contact on 2/3 rd's of the face of the rotor.

I have an '08 ABS, so I'm curios if they function well with the ABS tone wheel, as far as it's location with these rotors, being within the proper air gap.. maybe I'll try a set when my OEM's finally give out...


Also, did you look closely at the caliper on the side where the disc lock colided with it, and stopped the rotation... if not, I suggest looking, just to insure it didn't "crack" anything on those fragile mounting posts...

I have a 2011 ABS and did the same thing. I had to shim the sensor away from the tone ring. Regarding the diameter it is interesting they are the same outside diameter but the wave takes some of that away. I bought the rotors and pads and I get pulsing some times. I did check the run out and they were straight. I am going to buy better pads if that doesn't cure the intermittent pulsing I will consider  it a fail. I will be at the national you can take a look at them.

I have an '08 ABS and bought those exact rotors.  They fit the wheel perfectly and the sensor gap was not a problem.  Braking performance matches the stock rotors.  I've had zero issues with approximately 8,000 miles on them.

I'm very interested in a long-term update and a link to buy!  Thanks for sharing.

I've had those Arashi rotors on my 08 since 42k miles, now at 74k. I had a minor vibe at first but new EBC HH pads sorted that out. Been happy with them since then.

Konehead, MOB, I did check my caliper and everything is ok since I didn't impact it hard enough to do damage.  Konehead the reason my brake lever would become unresponsive was because the rotor was so bent that it spread open the calipers and when I applied the brakes it took several squeezes to get the calipers back on the rotor.  So far everything is good, no pulsing or vibrations.

The link for the rotors is:  https://www.ebay.com/itm/Front-Brake-Discs-Rotors-Pads-For-Kawasaki-Concours-14-ZG1400B-Ninja-ZX14R-06-14/283315896589?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649

The pads make complete contact on the surface of the rotor.
