Complete reinforced chain kit FRANCE EQUIPEMENT of original size so no 428, crown 43 to 50 teeth, sprocket from 13 to 17 teeth to choose from. Ideal for starting fresh on your YAMAHA SR 125 motorcycle, 4 versions to choose from:
-Reinforced: with a reinforced 428HG chain
-Hyper Reinforced O'ring: with self-lubricated RK428SO chain with o'ring seals for less maintenance and reinforced.
-Hyper reinforced with an excellent quality and very resistant RKGB428KXZ chain.
-Hyper reinforced XW'RING: With a chain RK428GXW 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 YAMAHA SR 125cc motorcycles are equipped with a fairly low range 14x49 chain kit (identical to the simple ultra reinforced 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
