The pinion and crown are cut from the best materials for optimal quality and life!
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 pull, so plan at least one exhaust line and a sport air filter to pull an extra tooth or two of the sprocket. One tooth on the pinion is 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: 111.43 KM / H in 15X50 teeth at 8000 rpm ....
