Complete chain kit reinforced FRANCE EQUIPEMENT original size so no 428, crown with number of teeth to choose from (30 to 50 teeth), pinion from 11 to 17 teeth. Ideal to start afresh on your MASH SEVENTY 125cc motorcycle, 4 qualities to choose from:
-Reinforced: 428H With a 428 REINFORCED chain
-Reinforced ring: RK428KRO with a 428 O'RING REINFORCED self-lubricated chain with o'ring seals for less maintenance and reinforced.
-Super reinforced: RK428 XSO with a 428 RX'RING SUPER REINFORCED chain
-Ultra Reinforced: RK428 GXW with 428 XW'RING ULTRA REINFORCED chain
The pinion and the crown are cut in the best materials for a quality and an optimal lifespan! You should know that the original MASH SEVENTY 125cc motorcycles are equipped with a fairly low range chain kit (identical to the first price here) and in 15x42 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
