Motorcycle Front Engine Sprocket 420-17T 17MM, Dirt Bike Sprocket for 50cc 70cc 90cc 110cc 125cc Dirt Pit Bike Mini ATV 4 Wheeler Moped Go Kart Quads

Easy to install. Fit perfect on his SSR 125. Changed the whole operation of the bike. Went from a 14t to 17t. Now we can ride in 1st. B4 this upgrade 1st gear was almost unusable. Highly recommend this if your running a 14t or 15t sprocket.. Worth the money. Its a clean, well manufactured and quality upgrade.

I bought the 16T front sprocket for my 125cc SSR ATV to get more top speed, since my OEM was only 13T. The difference is noticeable. first gear is much more usable now, and I definitely get a higher top speed. Installation was easy, and the quality seems solid. Looking back, I wonder if a 17T might have been even better option

I bought a Honda Little Cub with a Daelim 110cc engine. The Little Cub cake with 14 inch rear wheels, the Daelim 110 engine was made for 16 inch, so the final drive was wrong, too short. This sprocket fit right in on the Daelim engine, and made the gears taller. The top speed of the bike went to am acceptable 85 km/h after the switch. Excellent!

I bought this for my Piranha 140 (YCF SP-3 150) and it works great. It is the biggest that you can go on this particular set up that I have YX140 before you will have the change the length of the chain. Be advised that this sprocket will make your chain run extremely close to your engine case and one chain come-off will produce case damage. Nothing to do with this product but should be thought about when changing out sprockets.

I bought my kids a 110cc Tao ATV. The unit itself is pretty nice and runs great. However in the stock gear ratio with a 14 tooth front sprocket and 37 rear sprocket was 2.6 and the quad would get stopped on minor inclines. The quad would also go up to 30 mph. I put in the 10 tooth sprocket in the front and changed the gear ratio to 3.7. This thing will climb over curbs and run up hills without any hesitation now. Putting in this sprocket also reduced the top speed to just under 20 mph which is perfect for smaller kids.When installing this sprocket you will need to use a chain breaker to take off two links from the chain since the sprocket is much smaller than the stock 14-tooth sprocket. If you are trying to increase the bottom end on a youth quad and limit the top end, this is the trick you are looking for. This sprocket is perfect for my needs.

Purchased this front sprocket to change the gearing on my recently purchased Icebear Champion 125cc (CT70 Clone). It fit perfectly and I went up by one tooth from stock to provide just a bit taller gearing in order to reduce the vibration with the previous gearing. I was very happy with this item. Installation was straight forward and matched the original perfectly.

Perfect sprocket to change up the gear ratio on my 250cc Motovox mini bike build. The bike has shorter tires than a dirtbike so this gear helps change up the ratio to compensate for the short tires. YouTube BLACK66

Gear it constructed out of heavy steel, but I couldn't get the clip to stretch out over the spline to sit into to groove. I just wrapped it with some mechanic wire... Been weeks and all kinda kids driving. Good so far
