The pinion and the crown are cut in the best materials
for quality and long life! You should know that the original APRILIA RS4 50cc motorcycles are equipped with a low range chain kit (identical to the first price here) and 12x53 teeth! You'll choose a bigger gear or a smaller crown for more top speed, and a smaller gear for more acceleration! Attention, a longer chain kit is more difficult to tier, so plan at least one exhaust line and a sports air filter to pull a tooth or two more sprocket. A tooth with a pinion is about 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
