Complete reinforced chain kit FRANCE EQUIPEMENT of original size so no 428, crown 58, 60 or 62 teeth, pinion of 13 or 14 teeth to choose from. Ideal for starting fresh on your APRILIA RS4 125 4T motorcycle until September 2011, 2 versions to choose from:
-Hyper Reinforced O'ring: with self-lubricated RK428KRO chain with o'ring seals for less maintenance and reinforced.
-Hyper reinforced XW'RING: With a chain RK428FEX Super reinforced X-ring, so with seal that maintain the lubrication! The top of the top!
The pinion and crown are cut from the best materials for optimal quality and life! You should know that the original APRILIA RS4 125cc motorcycles are equipped with a fairly low-end 13X60 chain kit (identical to the ultra-reinforced simple here)! You will choose a larger cog or a smaller crown for more top speed, and a smaller cog for more acceleration! Attention, a longer chain kit is more difficult to pull, so plan at least one exhaust line and a sport air filter to pull an extra tooth or two of the sprocket. One tooth on the pinion is approximately equivalent to 5 teeth on 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: 107.14 KM/H in 15X52 teeth at 8000 rpm
It will be: 111.43KM/H in 15X50 teeth at 8000 rpm
