Complete chain kit reinforced FRANCE EQUIPEMENT original size so no 420, crown with number of teeth to choose from (50 and 51), pinion of 11, 12, 13, 14, 15 teeth to choose from. Ideal to start afresh on your BETA RR 50 motorcycle, 4 quality choices:
-Reinforced: With a 420R REINFORCED chain
-Super reinforced: With a 420SRG SUPER REINFORCED chain
-Hyper Reinforced: With a RK420MS HYPER REINFORCED chain
-Reinforced O'Ring: With a RK420MRU REINFORCED O'Ring chain
The pinion and crown are cut from the best materials
for optimum quality and lifespan! You should know that the original BETA RR 50cc motorcycles are equipped with a fairly low range chain kit (identical to the first price here) and in 12x51 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 upgrade, so plan at least an exhaust line and a sport air filter to get 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
