{"title":"Sprockets","description":"\u003cp\u003eThe low end torque acceleration and the top speed of your bike or scooter highly depends on the size of the sprocket you place in your front and rear wheels. We at AZ Scooter Parts offer a wide variety of sizes and shapes of these sprockets to our customers. This allows our customers to adjust top speed and low end torque acceleration according to their requirements and needs. For instance, if one were to use a smaller sized sprocket for the front countershaft, then their top speed would decrease, while their low end torque acceleration would increase and for the rear sprocket it would be it would be vice versa, meaning a smaller sprocket would increase top end and a loss of take off speed.. Similarly, other variations would result in different changes to your top speed and low end torque acceleration.\u003c\/p\u003e\r\n\u003cp\u003eAZ Scooter Parts offers the highest quality sprockets for greater efficiency of your scooter or bike.
