Rear sprocket

The rear sprocket, also known as the rear gear or rear pinion, is the large sprocket on the rear axle of your moped or scooter. Together with the front sprocket and the chain, it determines the gear ratio, and thus the top speed and acceleration performance of your vehicle.

When choosing, pay attention to the number of teeth, the chain size (such as 1/2×1/4 or 415), and the mounting method that fits your model. On this page, you will find rear sprockets for various makes and types, from classic mopeds to dirt bikes and scooters.
