Custom rear sprocket for motorcycle – Stunt, Cafe racer

We make rear sprockets to your special order. A specific number of teeth, a type of chain and a design prepared for a specific motorcycle model or according to the specified dimensions of the sprocket mounting on the wheel – we have been producing such sprockets for you since 2010. Hundreds of designs, patterns, models allowed us to create sprockets of the highest quality.

The rear sprocket of a motorcycle, in the case of a system equipped with a drive chain, is the last element that transmits the power and torque of the engine to the rear wheel. A feature of the rear sprocket is the possible installation of a component with a different number of teeth, which affects the dynamics of the motorcycle. The principle is simple: a sprocket with fewer teeth allows you to increase the maximum speed of the motorcycle at the same engine speed. Such a change also reduces dynamics, acceleration. A smaller sprocket will wear faster because the drive chain is braided over fewer teeth when transferring power to the rear wheel. Therefore, the tooth outline and the material of the sprocket are very influential. As a standard, we make rear sprockets from wear-resistant steel, which makes them durable and resistant to high loads. We CNC-mill aluminum sprockets exclusively from 7075 T6 aluminum alloy, which is one of the most durable alloys available on the market (used in aerospace). Although less durable, they are on average 60% lighter than their steel counterparts. The most important feature affecting rear sprocket wear, however, is proper system maintenance. Poor tension or even minor damage to the chain clearly accelerates the wear of the rear sprocket, which is particularly noticeable when a new sprocket is mounted to an old drive. For this reason, if replacing, it is suggested to purchase the entire chain drive consisting of the chain and the rear and front sprocket. The difference in wear between steel and aluminum sprockets decreases as the number of teeth increases. The larger the aluminum sprockets (60,65,70 teeth), the wear resistance approaches that of steel sprockets. At the same time, the larger the rear aluminum sprocket, the greater the difference in weight compared to the heavier steel sprocket. That’s why we always recommend making larger sprockets from aluminum.
