The pinion and the crown are cut in the best materials for a quality and an optimal life! It is necessary to know that of origin, the YAMAHA R1 1000cc motorcycles are equipped with a chain kit of low range (identical to the first price here) and in 17x45 teeth! You will choose a bigger sprocket or a 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
