Compatible with the stator coil, magnet coil and generator charging coil of the Yamaha YZF-R25 motorcycle (compatible with models from 2020 onwards).

This product is an original Yamaha YZF-R25 (model code YZF250-A, year of manufacture 2020) magneto ignition coil (alternator coil), specifically designed for the Yamaha YZF-R25 (model code YZF250-A, year of manufacture 2020), a powerful entry-level sport motorcycle. It is compatible with the 321cc parallel-twin engine and electronic fuel injection of this model, ensuring stable and efficient power delivery for this small sport motorcycle, known for its high-revving capability. The ignition coil is a crucial component for resolving charging issues and ensuring the proper functioning of the ignition and fuel injection systems. 【Main Product Information】 Compatible Model: Yamaha YZF-R25 (Model: YZF250-A) Compatible Year: 2020 Important Note: Parts may be updated for R25 models from other years (e.g., 2015-2019 or 2021 onwards). This product is specifically for the 2020 model year. Please check your vehicle's year of manufacture before purchasing. Engine Type: 321cc four-stroke parallel twin with dual overhead camshafts (same platform as MT-03 and R3). Function: This product is the main component for generating power to the ignition system. In the operation of a high-revving, small-displacement twin-cylinder engine, it must provide a stable three-phase power supply to the following systems: Electronic Fuel Injection: Supplies the ECU, electronic throttle (if equipped), and fuel injectors with precise operating voltage. Ignition system: Supplies power to the two ignition coils and ensures a strong spark. Charging and auxiliary system: Charges the battery and powers all LED lights, instruments, sensors, etc. Targeted fault symptoms: This product helps resolve common YZF-R25 (2020 model year) faults caused by a stator coil failure: unusually rapid battery discharge requiring frequent jump-starts or charging; fuel injection warning light or faulty instrument panel reading; noticeably dimmed headlights, especially at idle. The motorcycle is difficult to start; the idle is rough; the engine stalls easily after starting. A multimeter will reveal that the charging voltage is below 13.5V or fluctuates significantly.
