The sprocket seems to be of good quality and the bolts are okay quality, but the retainers and tool aren't that great.

All parts were not including. The screws and the wrench were not including as advertised.

Installed on my bd125-2 the moment I got it. Used it to replace the stock 420 14t. Took only a few minutes. Perfect fit. Having the larger front sprocket makes for smoother acceleration and higher top end.

Mounted to a window motor for a home made gold prospecting trommel. Works great. Pretty standard sprocket.

I bought a 12T sprocket for my son's Kayo Bill 125 and my daughter's Kayo Fox 70. Fit on both was as expected. Quality seems OEM level, at least for a Chinese ATV. For $6, it's a nice improvement on the stock gearing and makes it a little easier to climb hills compared to the stock 13T sprocket.

This product was half the price that my local part store wanted, and most part stores said they can't even get it for me. This one had beautiful colors and designs, and was amazing quality. My mini bike now runs like a charm.

(3⭐️s)15T SprocketCame with: 1 Sprocket and 1 RetainerPROs:- Works- It fits- Easy to installCONs:- Did not come with everything that was shown in the pictures, as well as the description.- The restrainer was poorly plated, with some of the plating coming off, and already showing corrosion.Overall: This was an okay product that works. I just wish it came with everything that was advertised and was better plated.
