The pinion and the crown are cut in the best materials for a quality and an optimal life! You should know that the YBR 125cc bikes are equipped with a low-end chain kit (identical to the first price here) and in 14X45 teeth! You will choose a larger sprocket or smaller crown for more top speed, and a smaller sprocket for more acceleration! Be careful, a longer chain kit is harder to tie, so have at least one exhaust line and a sports air filter to pull a tooth or two of sprocket more. A tooth with the pinion is equivalent to 5 teeth to 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
