ABS Phonic Wheel (Front) - 2B004778 - For Aprilia RS 660 & Tuono 660
SKU: MB00333-PHONIC-2B004778
Genuine Aprilia / Piaggio front ABS phonic wheel for Aprilia RS 660 and Tuono 660 models. Original part number 2B004778, this factory encoder ring works with the front wheel speed sensor to provide accurate wheel-speed information to the motorcycle's electronic systems.
A direct replacement for the original component, it is ideal for replacing a damaged or distorted phonic wheel or for completing an additional front wheel for road or track use.
Original Aprilia / Piaggio Part
The 2B004778 phonic wheel is an original Piaggio Group component manufactured to the correct dimensions and encoder pattern for compatible Aprilia 660 models.
As the front wheel rotates, the ring passes the wheel speed sensor, allowing the motorcycle to accurately monitor wheel rotation for the ABS and associated electronic systems.
Perfect for a Second Wheel Set
In addition to replacing an existing phonic wheel, the 2B004778 is particularly useful when building a second set of wheels for track or road use. Installing a dedicated phonic wheel means the spare front wheel can be kept complete and ready to fit without repeatedly transferring the original ring between wheels.
