FRANCE EQUIPMENT reinforced chain kit for motorcycle YAMAHA WR 125cc from 2009

Complete chain kit reinforced FRANCE EQUIPEMENT original size therefore no 428, crown with number of teeth to choose from (49 and 51), pinion of 13, 14, 15 teeth to choose from. Ideal to start afresh on your YAMAHA WR 125cc motorcycle, 2 versions to choose from:

-Reinforced O'ring: with self-lubricated RK428KRO chain with o'ring seals for less retention and reinforced.

-Super reinforced RX'RING: With a chain RK428XSO Super reinforced X-ring, therefore with seal which maintains the lubrication! The best of the best!

The pinion and the crown are cut in the best materials for a quality and an optimal lifespan! You should know that the original YAMAHA WR 125cc motorcycles are equipped with a fairly low range 14x53 chain kit (identical to the ultra reinforced single here)!

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!

Attention in crown of 48 it will be necessary to change the screws of the crown because this one will be very close!
