The magnetic coil stator is compatible with the Yamaha YFM450F Grizzly 450 Kodiak 450 ATV models from model years 2011 to 2016.

This product is an OEM-quality magnetic coil (generator coil) specifically designed for the Yamaha YZF-R1 (model years 2015–2023), the current flagship of Yamaha's superbike range. It was engineered for seamless integration with the revolutionary 998cc CP4 inline four-cylinder engine with transverse shaft drive and the highly integrated 6-axis IMU electronic system, covering the entire 2015–2023 model range. A true "powerhouse" of modern 1000cc superbikes, this coil delivers an extremely stable, clean, and abundant current to the complex electronic engine management and racetrack systems, ensuring peak performance even under extreme conditions. 【Important Product Information】 Compatible Models: Yamaha YZF-R1 (2015–2023 models, including standard, R1M, and special editions) Compatible Years: 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023 Important Note: R1 models prior to 2015 (e.g., 2009–2014 models) have a different design and are not compatible. Please check your vehicle's year of manufacture. Engine and electronic controls: 998cc inline four-cylinder engine with CP4 transverse crankshaft, equipped with a 6-axis IMU (Inertial Measurement Unit), variable valve timing (VVA), traction control (TCS), wheelie control (LIF), launch control, track ABS, and other advanced electronic controls. Component function: This product is the primary power generation component for the magneto ignition. At engine speeds up to 14,000 rpm and high acceleration during track use, the coils must ensure absolute stability and provide a stable and uninterrupted power supply to the following systems: Electronic Control Unit (ECU): Powers the 6-axis IMU, engine control unit, electronic throttle control actuator (YCC-T), quickshifter (QSS), and engine brake management system (EBM). High-performance ignition and injection: Powers the high-performance multi-point ignition coils and fuel injectors. Charging and Data Acquisition System: Charges the high-performance lithium battery and powers the color TFT display, data logger, and lighting. Troubleshooting: This product addresses typical issues encountered in the Hyundai R1 on the track or in road use, caused by damage to the stator coil under high load: random alarms or malfunctions of various electronic control systems (e.g., abnormal interventions by the traction control system (TCS) and boost control (LIF)), frequent switching to protection mode, or impaired operation. Rapid and significant battery discharge after track days or intensive driving, affecting the operation of the electronic control systems. Perceived power loss at high RPMs (e.g., when accelerating out of corners), flickering dashboard lights, vehicle restarts, or TFT display malfunctions. The fuel injection warning light is illuminated continuously, and a diagnostic tool displays charging system error codes (e.g., error code "11" or similar). The charging voltage is unstable and exceeds 14.0 V or fluctuates significantly.
