This ABS Tone Ring (also known as a Phonic Wheel, Sensor Ring, or Pulse Ring) is modified to correct the factory Speedometer from reading HIGH.
 
This ring corrects a 4% speedometer mismatch, bringing the indicated speed closer to true GPS speed.
 
Designed for use with the stock tire.
 
This Ring is for the Rear Wheel only. A Front Correction Ring is not required.
 
It is necessary to perform an APRC (Aprilia Performance Ride Control) calibration after the installation of the new ring.
 
If your Speedometer mismatch is different from 4%, please reach out by email before ordering.
 
Made from from Mild Steel, Powder Coated Matte Black. 
Made in US
