Tone Wheel POLINI ABS Rear/Front 290.0301 is a precision component designed to enable advanced braking system functionality on your Vespa GTS 310cc HPE Euro 5+ scooter. This wheel works in conjunction with your vehicle's ABS and ASR (Anti-Slip Regulation) systems to monitor wheel speed and prevent brake lock-up during emergency stops or slippery conditions.

The tone wheel reads rotational data and communicates it to your scooter's ABS control unit, allowing the system to modulate brake pressure in real-time. This keeps your wheels from skidding, maintaining traction and steering control when braking hard. The component is engineered for both rear and front wheel installation, with configurations supporting 44 teeth and specific mounting patterns (5-hole rear, 6-hole front) tailored to your model.

Assembly Information

Instruction video

Install both tone wheels to ensure the correct operation of the ABS system. Threadlocker must be applied to the fixing screws, and both tone wheels must be tightened to the specified torque. Note: The video shows the installation procedure for the rear wheel only. Perform the same procedure on the front wheel. After installing the tone wheels, recalibrate the scooter's ASR system to ensure proper parameter alignment.

Installation requires careful torque application and threadlocker on all fasteners to ensure reliability and safety. After fitting both wheels, ASR system recalibration is essential to align all parameters correctly. This part is intended for performance and race applications where precise braking response is critical.
