Yamaha YZF-R1-STATOR-REG-RECT Stator Regulator Rectifier

Description:

The Stator & Voltage Regulator Rectifier with Gasket is used in motorcycle and ATV charging systems to generate electrical power and regulate voltage for stable battery charging and electrical system operation. The stator produces alternating current (AC) from engine rotation, while the regulator rectifier converts it to direct current (DC) and controls voltage output to prevent overcharging. Commonly installed in motorcycles, scooters, and small utility engines where reliable charging performance is required for ignition, lighting, and electronic systems. Repair technicians and OEM service providers use this assembly for charging system repair, electrical fault diagnosis, and replacement of failed stator or regulator components.

Applications:

This stator and regulator rectifier assembly is commonly used in motorcycle charging systems including sport bikes, cruisers, dirt bikes, and ATVs where engine-driven alternators provide continuous electrical output for battery charging, ECU operation, fuel injection systems, and lighting under varying RPM conditions in both street and off-road environments.
