Product Description
Not made in China! Made from High Carbon Steel SAE 1045/49/SCM415. Fits 428 Chain. See picture for exact measurements. Check your current tooth count before ordering! Larger size sprockets in the rear give you more take off power with less top speed. Smaller rear sprockets give you more top end speed with a slower take off. Larger rear sprocket may require removal or modification of chian and sprocket guard, as well as need a longer chain. Fits many Chinese made "off brand" ATV and dirt bikes with Honda clone type motors. Fits some, but not all Coolster 110 and 125 models. Customers have told us this is the size for Apollo ATVs. We have also used these on Jiangsu Tiking / Kinroad ATVs. We use these sprocket in our shop to modify Taotao 125cc model ATVs with a 428 chain which may include 135DU, Cheetah, New CHeetah, TForce, New TForce, Raptor, Rex, 125e, 125h. Verify sprocket measurements before ordering. Not all Taotao's will use this 428 rear sprocket, including the 125F1. If this sprocket doesn't fit your applciations, simply give us your sprocket measurments and we will see if you have your sprocket. 100's of sprockets available!!! 56 tooth is lower quality than the other sprockets. 45 tooth option is lower OEM quality. 10+Product Videos

worked perfectly
6 yr olds 125 was about 25 mph with stock sprockets(13 front/41 rear)and seemed weak with the throttle governed. I went to 12 on the front and 46 on the rear. It's now about 20 mph with full throttle. I can now govern the throttle for 10 to 15 mph and still have plenty of torque for hills. Get the modified retainer for the front sprocket. This setup required a chain that was 4 links longer than stock. Also had to snap off the flimsy skid plate under the rear sprocket. The plastic chain guard still fit.

Game changer
If your like me and got your kids a Chinese atv/bike because you didn't know if they would ride, or not. Then i know your underwhelmed by a few things like take off power. A Larger rear sprocket, along with smaller front made a world of difference. I can't stress that enough. My son's 125 Coolster (chinese atv) is ok for what it is. It was fast, but It wouldn't climb much without a run and start. Now it'll walk up steep trails like an atv should. Went up from a 31 rear to a 37. From a 13 front down to 12. And upgraded chain. If any of you are considering this, jump on it. Your kids will be happy you did. I would also suggest carb, plug, cdi, and battery upgrades for the Chinese bikes/atv. But this is a 1st must mod
