Kit of complete reinforced FRANCE EQUIPMENT of size origin thus not of 525, crown with number of teeth to the choices (36, 37, 38, 39, 40, 41, 42, 43 and 45 teeth), pinion of 14, 15 and 16 teeth at your choice. Ideal to restart on your DUCATI HYPERMOTARD 821, 2 quality with the choices:
-Super reinforced: RK525 FEX With a chain 525 RX'RING SUPER REINFORCED
-Ultra Reinforced: RK525 RO with 525 XW'RING ULTRA REINFORCED chain
The pinion and the crown are cut in the best materials for a quality and an optimal life! You should know that the original DUCATI HYPERMOTARD 821cc motorcycles are equipped with a chain kit of low range (identical to the first price here) and in 15x45 teeth! You will choose a larger sprocket or smaller crown for more top speed, and a smaller sprocket for more acceleration! Be careful, a longer chain kit is harder to tie, so have at least one exhaust line and a sports air filter to pull a tooth or two of sprocket more. A tooth with the pinion is equivalent to 5 teeth to 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
