Compatible with the stator, ignition coil and charging coil of the generator of the Yamaha MT-03 / YZF-R3.--DTEKGAZ

This product is an OEM-spec stator coil (magneto/generator coil) specifically designed for Yamaha's lightweight and powerful twin-cylinder motorcycle platform. It is primarily compatible with the MT-03 (street version) and the YZF-R3 (sport version) and also supports derivative models such as the R25, which uses the same 321cc parallel-twin engine (exact model year to be verified). The coil covers models from 2019 to 2021 and ensures a stable and efficient power supply to this high-revving twin-cylinder engine and its electronic fuel injection system. It is therefore a professional replacement part for resolving charging issues and optimizing vehicle performance. 【Important Product Information】 Compatible Models (based on the 321cc twin-cylinder platform): Yamaha MT-03 (street motorcycle, 2019-2021 models and similar), Yamaha YZF-R3 (sport motorcycle, 2019-2021 models and similar), Yamaha YZF-R25 (some international models; please check compatibility with your product or VIN). Note: Wiring harnesses and connectors may vary slightly depending on the market and year of manufacture; comparison with your product is essential. Engine Type: 321cc 4-stroke parallel twin, liquid-cooled, dual overhead camshafts (DOHC). Function: This product is the primary power generation component for the magneto ignition. At high engine speeds, the coil must generate a stable three-phase current to power the following precision systems: Electronic fuel injection: Supplies power to the engine control unit (ECU), electronic throttle, fuel injectors, etc., ensuring precise fuel injection. Ignition system: Supplies power to the two ignition coils and generates a strong spark. Charging and auxiliary system: Charges the battery and powers all of the vehicle's LED lights, instruments, sensors, etc. Troubleshooting: This product addresses common problems in modern twin-cylinder vehicles caused by a stator coil failure: Unusually rapid battery discharge requiring frequent jump starts. Illuminated fuel injection fault warning light or faulty instrument cluster reading. Dim headlights, especially at idle. Starting difficulties, rough idling, and stalling after starting. Charging voltage below 13.5V or excessive fluctuations, as measured with a multimeter.
