Very high quality chain kit, crown and pinions with number of teeth to choose from, cut in the best steels and made in France! 5 chain qualities to choose from and even available in self-lubricating!
Complete chain kit reinforced FRANCE EQUIPEMENT original size so no 428, crown with number of teeth to choose from (50 or 52 teeth), pinion 13, 14, 15, 16, 17, 18 and even 19 teeth to choose from. Ideal to start afresh on your 125cc DERBI motorcycle, 5 versions to choose from:
-Reinforced: With a chain RK 428 HZ STANDARD Reinforced
-Ultra reinforced: With an ultra reinforced RK 428 MXZ chain
-Reinforced O'ring: with self-lubricated RK428KRO chain with o'ring seals for less retention and reinforced.
-Super reinforced RX'RING: With a chain RK 428 XSO HYPER Reinforced X-ring, therefore with seal which maintains the lubrication! The best of the best!
-Ultra reinforced XW'RING: With an RK 428 GXW Ultra Reinforced X-ring chain, therefore with seal which maintains the lubrication! The best chain on the market, extremely long service life!
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 125cc motorcycles are equipped with a fairly low range 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 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

Originally, the DERBI GPR 125 motorcycles are mounted with 16X50 teeth!
