Fit my 2024 condor 150 (grom clone) perfect. Just this cheap and simple upgrade completely changed how the bike shifted in a good way. Not a whole bunch of speed gained, but the bike can now actually build speed without high rpm. Had to make a small bit of clearance on the housing but a grinder made quick work of that. Bolted right in with the stock chain. Would definitely recommend if you’re looking for a simple, cheap, but effective upgrade, this is it!

Fit my Kayo fox 70 just fine. The metal bracket that comes with it is junk, chain hits it because it’s to big. Used original.

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!

The qaulity of this 17t sprocket is pretty bad. The machine finish is very rough and the teeth are horrible. If you have a decent qaulity chain this sprocket will eat it up and shorten its life. However, the gear works... These gears are likely the gears that didn't pass Qaulity Control inspection and were sold for basically scrap to a reseller. But like I said it works, it's cheap, and shipping was quick.

FYI for others ordering this item. It comes with both the snap ring and the bolt-on retainer with bolts for attaching it. So bottomline, you have 2 options for securing this sprocket to the shaft. I have not installed this yet, but it appears to be good quality = to OEM. This is for my SunL 110 cc 4 wheeler - gearing it down to provide better power for going up hills. The original gearing is stupid - goes way too fast on the flats but not enough power to climb hills.
