Please count your number of sprocket teeth, and check your bolt pattern distances and center opening
These sprockets are new and within +- 2 teeth of specified OEM sprocket sizes from Reputable Sprocket Charts. Smaller number of teeth give you faster acceleration. Larger number of teeth give you more top speed.
