The pinion and the crown are cut in the best materials for a quality and an optimal lifespan! You should know that the original YAMAHA DT 50cc motorcycles from 2007 to 2013 50cc are equipped with a fairly low range chain kit (identical to the first price here) and in 14x53 teeth!
You will choose a bigger pinion or a smaller crown gear for more top speed, and a smaller pinion for more acceleration! Be careful, a longer chain kit is more difficult to upgrade, so plan at least an exhaust line and a sport air filter to get a tooth or two more sprocket. A tooth at the pinion is approximately equivalent to 5 teeth at the crown!
Example :
If your speed in 14X52 teeth is 100 KM / H at 8000 rpm
It will be: 104KM / H in 14X50 teeth at 8000 rpm
It will be: 107.14KM / H in 15X52 teeth at 8000 rpm
It will be: 111.43KM / H in 15X50 teeth at 8000 rpm
