Restore Silent Start Performance on Your Honda Scooter

Modern Honda BS6 scooters (like the Activa 125, Activa 6G, Dio, and Grazia) are equipped with a revolutionary Alternating Current Generator (ACG) starter system. Unlike traditional scooters, there is no noisy starter motor or grinding starter gears. Instead, the stator coil itself acts as a brushless starter motor to spin the engine silently.

For this “Silent Start” to work, the ECU must know the exact position of the flywheel down to the millimeter. This is the job of the ACG CKP (Crankshaft Position) Hall Sensor.

When this sensor fails or burns out, the ECU can no longer coordinate the electromagnetic coils, resulting in a self-start failure and triggering Error Code 52 (CKP Sensor Circuit Malfunction).

Our premium replacement Activa CKP Hall Sensor is designed to meet exact OEM standards. Weighing 0.4 kg, this sensor can be wired directly onto your existing stator plate, eliminating the need to spend thousands of rupees on a complete stator coil assembly.

Key Features & Benefits:

• Direct Fault Resolution: Eliminates self-start failures, engine misfires, and dashboard MIL error codes caused by CKP sensor faults.
• ACG Silent Start Optimized: Built specifically to communicate high-speed magnetic signals to the Honda ECU for brushless starting.
• Premium Quality Materials: Designed with high-temperature resistant casings and high-grade copper wiring to withstand engine oil heat inside the generator cover.
• Huge Cost Savings: Workshops and scooter owners can swap just this sensor on the stator plate, saving up to 80% compared to buying a full stator unit.
• Universal Honda BS6 Fitment: Fits Honda Activa 125 BS6, Activa 6G, Dio BS6, Grazia BS6, and other Honda models using the ACG silent-start system.
