The sprocket and crown are cut into the best materials for optimal quality and service life! We need to know that from the beginning, motorcycles YAMAHA DT 50cc MX 50cc are equipped with a fairly low range chain kit.
You will choose a bigger pinion or a smaller crown for higher speed, and a smaller pinion for more acceleration! Be careful, a longer chain kit is harder to pull, so plan at least one exhaust line and a sports air filter to pull one tooth or two sprocket in addition. A pinion tooth is around equivalent to 5 teeth to the crown!
