Pinion and crown are cut from the best materials
for optimum quality and longevity! You should know that the original APRILIA RS 50cc motorcycles are equipped with a fairly low range chain kit (identical to the first price here) and in 12x47 teeth! You will choose a larger cog or a smaller crown for more top speed, and a smaller cog 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 an extra tooth or two of the sprocket. One tooth on the pinion is approximately equivalent to 5 teeth on 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: 107.14 KM/H in 15X52 teeth at 8000 rpm
It will be: 111.43KM/H in 15X50 teeth at 8000 rpm
