Quick overview
AFAM Standard front sprockets (- in the reference) is a replica of your original front sprocket and is used for most motorcycles.

AFAM Racing sprockets are computer designed. Light built but still providing sufficient safety. They are especially designed to save weight in racing applications, usually to
fit a smaller and thus lighter chain. In this case they are aligned towards the engine.

AFAM Self-cleaning front sprockets (+ in the reference) are available for MX and Off-Road use. They have on each side of the tooth bottom, a groove which evacuates sand and mud from the sprocket, this way dirt does not accumulate between sprocket and chain. This accumulated dirt causes over tension to the chain as a result sprocket and chain wear out very quickly, and may even block your bike. With this mud grooved sprocket you avoid these problems.
