Complete chain kit reinforced FRANCE EQUIPEMENT original size so no 420, crown with number of teeth to choose from (45, 48, 50, 52, 53 and 60), pinion from 11 to 16 teeth to choose from. Ideal to start afresh on your DERBI SENDA DRD RACING SM, 4 quality choices:
-Reinforced O'ring RK 420 SO: with 420 O'RING self-lubricated chain with o'ring seals for less maintenance and reinforced.
-Super reinforced: 420 SRG With a 420 SUPER REINFORCED chain
-Reinforced: 420R with 420 REINFORCED chain
-Hyper reinforced: With a chain RK 420 MS HYPER REINFORCED
The pinion and the crown are cut in the best materials for a quality and an optimal lifespan! You should know that the original DERBI SENDA DRD RACING SM motorcycles are equipped with a fairly low range chain kit (identical to the first price here) and 14X53 teeth! You will choose a bigger pinion or a smaller crown gear for more top speed, and a smaller pinion for more acceleration! Be careful, a longer chain kit is more difficult to pull, so plan at least an exhaust line and a sport air filter to pull a tooth or two more sprocket. A tooth at the pinion is approximately 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
