Reading the size
Sprockets are made for a chain size. The tooth spacing follows the chain pitch and the tooth width follows the chain width, so a 520 chain needs 520 sprockets.1
The tooth count is the other number that matters. The stock front and rear counts for each bike are in the table above.
Changing the gearing
More teeth on the rear, or fewer on the front, gives quicker acceleration and a lower top speed; the gearing calculator shows the exact change in ratio and speed. A different tooth count can also need a different chain length: the chain length calculator gives the link count.
When to replace them
Replace sprockets with the chain, not on their own. A worn sprocket wears a new chain quickly, and the chain maker D.I.D advises changing chain and sprockets together.2
