The Kunray motor was clearly used and poorly reassembled after it was broken or something, pretty ridiculous, avoid.

Want a crazy power house for the second stage of your bike? This is it. Loads of torque to carry that front end in the air and plenty of speed to keep you going. If your coming from an my1020 motor I’d suggest you have some handle bar grips you can keep a hold of lol.

The media could not be loaded. Legit motor , not sure what sprocket size it came with but just like kunray my1020 motor all sprockets fit on it , biggest tire it’ll fit is 2.75-10 unless you have swing arm for mx650

Kunray used to be the best. Now they suck. QC is out the window. The holes for the mounting hardware are not threded. They must have missed that part during manufacturing. Also i bought a kit from them and they send me a 48V controller instead of the 72300 that was supposed to come with the kit. FU Kunray!!!

On my mx500 this motor’s mount broke clean off on the sprocket side. The casting is too weak. Motor runs great and has good power. Real shame that it broke after only about 10 miles and just a few days outside of return.
