I did not notice this problem when I installed the new brake rotor sent to me by CSC. Even if the holes are the correct size and aligned properly, you can still cause the brake rotor to warp if you don't install it carefully. I don't doubt that some good brake rotors were installed improperly at the Zongshen factory. If so, removing the brake rotor, and carefully re-installing it, might solve the problem.

What part of the hole is supposed to make for the alignment of the disc? The 10mm hole thru, or the outer 16mm step?

I first align the inner, 10 mm hole. Then I evenly tighten the bolts until all of them contact the disc. Finally, I incrementally tighten all the bolts in a star pattern, until all the bolts are tight.
If you have any problems with the Zongshen rotor bolts, you can also install brake rotor bolts designed for the Kawasaki KLR650. https://www.rockymountainatvmc.com/p...lt-Kit?v=12127

I don't know. The bolts seems fine. Is the holes (namely, the disc itself) I suspect.
You method is the same as mine. But getting the 6 bolts to enter the 10mm hole was hard, I couldn't do it by hand and ended using the allen head, not much force, but noticeable. I'll try againg next saturday, taking more time to check if I can detect where the misalignment is. |

Brakes
Keep us updated with replacement brake pads. I feel it is the biggest fault in the motorcycle(AKT 250TT in Colombia). Don't know if it's soft pads or not a big enough caliper pot?

I can confirm that Honda XR 250 / Tornado pads fit and work very well.
Of course for those you have a wide range of options, Price and quality wise to choose. I also can confirm that the disc IS warped, but -only- when fitted in the Wheel hub, taking it out and putting on a plane table shows it's flat as it should be. |

Spud have you installed your EBC FR185 pads yet? And Juanro how many miles so far on your new pads and still not noticing any issues with the spring removed? I just ordered a set from Amazon of the FR185s pads. Hoping will help the stopping power and feel in the front by a fair amount.

No, it snowed this morning in East Idaho. I might not install the FA185 pads until next spring.

After my last hammering session it seems to be working pretty well. I've put about 1000km with the new Honda pads and no spring without any issue. Braking power is good, I use the bike both near max speed in the highway for a couple hours two or three time a week and in some dirt and sand trails on weekends and braking is flawless in both situations.

Thanks for the info Juanro. I installed the new ebc pads yesterday and definitely they seem loose when first installing, but you are right you can't fit the retaining clip/spring in. I've never had a bike that didn't have two pins attaching the pads as the rx3 brakes have one so that might be the reason for that too. Haven't rode it yet but will ride it confidently thanks to Juanros vote of confidence.

Perhaps the front brake caliper of the RX3 motorcycles imported into the United States is different. However, I successfully installed the EBC FA185 brake pads into the front brake caliper of my RX3 using the stock, Zongshen pad spring. You can read my report at the following thread.
