Complete reinforced chain kit FRANCE EQUIPEMENT of original size in 420, crown from 48 to 59 teeth, pinion from 11 to 16 teeth. Ideal to start fresh on your mécaboite DERBI .
The pinion and the crown are cut in great materials for a good quality and a good lifespan! You will choose a larger cog or a smaller crown for more top speed, and a smaller cog for more acceleration! Be careful, a longer chain kit is more difficult to pull, 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 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
