The purpose of a sprocket in a bike's drivetrain system is to transfer power from the pedals to the wheels by engaging with the chain, allowing the rider to propel the bike forward.
generally a racing BMX is built for speed, hence they are made lighter than normal bikes and also have a bigger sprocket witch enables the driver( back sprocket) to go faster.
The main difference between LHD (left-hand drive) and RHD (right-hand drive) BMX bikes is the placement of the drivetrain components. In LHD bikes, the sprocket and driver are on the left side of the bike, while in RHD bikes, they are on the right side. This affects the way the bike feels and performs, particularly when doing tricks or riding in certain directions. Riders may have a preference for one over the other based on their riding style and comfort.
Sprockets are a kind of wheels that have teeth to keep a chain in place an moving from the action made by another sprocket. Sprocket wheels are used for bikes and on roller chains.

The best rear sprocket for your Skyteam ST50 PBR Monkey Bike would be the 32 Tooth Rear Sprocket for PBR 50cc ~ 125cc monkey bikes. If you shop around you can get one for a good price online.
to have lots of fun
A rear sprocket is almost always made of steel, as it has to stand up to a fair amount of wear from the chain. For bikes with multiple sprockets (AKA cassettes) you can sometimes find titanium sprockets to save a bit of weight on race bikes. They're horribly expensive and don't last very long.
You need a chain meant for single-speed or internally geared bikes, cut to the right length.
The Shimano RD-M592 rear derailleur for mountain bikes has a maximum sprocket size of 34 teeth, a total capacity of 43 teeth, and is compatible with 9-speed drivetrains.
for fun, as they serve no other purpose do they?
For the most part, no, but there are instances where trail bikes are the same as motocross models but with softer suspension, a bigger tank, a mellowed engine, and lights. These bikes can do okay on a track. However, purpose built motocross bikes are always best for the track, just as purpose built trail bikes are best for the trails.. Hope this is helpful!
ABS is the abbreviation of the Anti-Lock Brake System in bikes.
