Description
Chainring 48 teeth Beta RR from Voca Racing
CNC aluminum sprocket from VOCA Racing for Beta Factory / RR SM after 2005 with 420 chain.
HQ sprocket from VOCA - light and robust
The sprockets are precision CNC-milled from an aerospace-grade aluminum alloy (AA-7075-T6). The choice of this high-quality alloy not only ensures a strength comparable to conventional steel sprockets, but also offers a significant reduction in weight and thus the load on the rear axle, which can be a decisive advantage, especially in racing.
The seamless, weld-free design of the VOCA sprocket ensures excellent structural integrity and optimizes power transfer from the engine to the rear wheel with minimal power loss.
Custom chains and sprockets
The Voca sprockets are available for many 50cc motorcycles, with different numbers of teeth and in different colours, so you can match the sprocket to your bike.
We also stock a large selection of rear sprockets from other manufacturers. We recommend replacing the entire assembly at once, i.e. also replacing the sprocket and chain, in order to increase the service life of all components through even wear.

Funstion of Rear procket
The rear sprocket of a motorcycle is an essential part of the chain drive. It is attached directly to the output of the gearbox and is connected to the front sprocket via a chain.
How can I tell if the sprocket is worn?
A worn or damaged sprocket may show signs such as metallic rattling noises, worn teeth, a loose chain, or difficulty shifting gears.
smaller or larger chainring?
- Sprocket with more teeth → improved acceleration
- Sprocket with fewer teeth → higher top speed
You also have to consider the gear ratio between rear chainring and front sprocket. The calculation is: number of teeth of rear sprocket / number of teeth of front spocket. A low ratio increases speed, while a high ratio improves acceleration.
To ensure optimal life, it is important that you do not neglect chain care, we recommend a special chain brush.
