I verified that the CF Moto Cforce 110 uses a 428 style gear and wanted to get a little more take off power as it is laggy when taking off on any type of incline. This 12 tooth gear is the smallest gear that will work with the stock bolts/retaining clip (stock is a 13 tooth) so I tried it and it was perfect (I had a 10 tooth with a snap ring to hold it in place and it was clunking around and only did 21mph). This 12 tooth goes 25 mph (stock was 27 mph) and it picks up speed a lot better so it is perfect!

Replaced a 428-13T sprocket on my son's 125cc Vitacci (Chinese) four wheeler to give it more low end torque. Change over was pretty simple. The only reason I didn't give it 5 stars is due to there being some metal burrs on the back side that wouldn't allow it to fit on the shaft fully. I used a file, but after a few minutes of not making any real progress, I switched to a Dremel with a grinding wheel which made short work of it. After that, it went on perfectly. It came with another retaining plate, but I had to use a bench grinder to thin out the outside edges around the bolt holes so the plate didn't interfere with the chain. Based on a few YouTube videos, I had expected to do that step anyway. My son rode all over the place today and seemed to be able to pull some fairly steep inclines that he couldn't previously. Cheap mod for more pulling power. Great value for the money.

The teeth on the inside of sprocket are to large to fot on the spline. The amount of teeth are correct, the hole size is correct, but the teeth on the spline side are not.
