420 14T 17mm Front Engine Sprocket Compatible with 50cc 70cc 90cc 110cc 125cc 140cc 160cc ATV Quad Dirt Bike Honda Honda Z50 CT70 Speed Mini Bike TaoTao Roketa Coolster Sunl Lifan

Works and fits as it should. Would buy again.

Fit my 125cc pitbike and was very affordable!

Went from a 13T front sprocket to this 17T on my daughters 110cc Coolster…. It went from high rpms at 15 mph to 22 mph and still has plenty of take off power

Fit nice

I used this for my 2019 Honda Grom, fits good. I got the 14 tooth, if your looking for stock gearing it's a 15 tooth. Going down to 14 gives you more torque but less speed. Stock, my Grom could go about 68, with the 14 tooth I was topping out at about 59. I also tried a 16 tooth, topped out at about 72.

I used this on a 125cc Coleman mini quad to help it on hill climbs. The smaller front sprocket helped a bit, which is all I was looking for. Install was simple.

Exactly what the title says. I purchased the 420 17t 17mm so I can get more top speed on my 125cc DB-x19 apollo only to find out that when I put my sprocket cover back on the chain started to rub the inside of the sprocket cover when the rear tire turned and it doesn’t help that my chain is a 428 and it’s already tight as it is. If I somehow find a solution to this then I will change my rating but until the it’s a one star for me.

It fit our Tao tao 125

It fits and works very good for a geo 110 cc 4 stroke bike better then factory setup.thanksghf
