Fitment

Sprockets wear out over time, resulting in many problems for you and your bike. For example,chain tensioning can become difficult, which may cause the chain to fall off and jam in the drive train. Or the chain may not roll off the sprocket smoothly as it turns, causing the wheel to lock up
To avoid these problems, you should replace your sprockets when you see the teeth are worn out. But don't settle for an inferior replacement part. You want something that's designed specifically for your ride and made for long-lasting performance.
This sprocket is designed to be a reliable replacement for worn sprockets for many different power sport vehicles using 428 chain sizes.

Shipping time expressed was actually faster than they claimed which was like around 2 months. It arrived in like 2 weeks if I remember right. Either way I was surprised to see the package arrive when it did. Understand that I couldn't even find another anywhere, so... I'm pretty happy. :)

Fit like a champ on a Tao 125-d ATV & increased the takeoff loadDown side is it lowered the topend speed by about 10MPHI went from a 37 tooth to this gem and lowered the front sprocket from 13 tooth to a 10 tooth, the chain was tricky bc the adjuster was limited but overall PERFECT!!

Have just fitted it, so cant tell how it wears, but fitted well. Too bad the seller only have these sizes would love to the option for choosing every tooth size.

This is a nicely crafted chainwheel, fit and finish is great, best I can tell short of an extended use report is that this is a top notch item. Works perfectly for my mechanical design project.

This fit great on a Honda mini bike. It is a 50cc motor and a smaller kids motorcycle. I am not sure the year but, it is an older bike the kids play with. The old sprocket had rust and we were worried it would break while someone was riding on it. I didn’t do the installation. I was told that it was not hard to install and seems to be made of sturdy material. The chain has not had any issues with slipping. It seems to be running smoothly.
