Compatible with the stator coil and magnet coil of Yamaha WR450F off-road motorcycles (models 2007-2011).--DTEKGAZ

This product is an original stator coil (alternator coil) for the Yamaha WR450F, a professional 4-stroke off-road motorcycle (model years 2007–2011). It was specifically designed for this model and meets the precise electrical specifications of the WR450F engine (with electric starter) from that era. The coil eliminates charging failures caused by coil damage, ensuring a stable and reliable power supply for this powerful single-cylinder engine during your most demanding off-road adventures. Please note: This product is an accessory for gasoline-powered off-road motorcycles. The stator structure is fundamentally different from that of electric vehicle models. Therefore, it is not interchangeable. 【Important Product Information】 Compatible Model: Yamaha WR450F, professional long-distance off-road motorcycle. Compatible model years: 2007, 2008, 2009, 2010, 2011. Important note: WR450F models from model years 2003 to 2006 use different designs (no electric starter or different ignition coil specifications) and are not compatible. Models from 2012 onward have also been updated. Engine specifications: 449 cc single-cylinder, four-stroke, liquid-cooled engine with electric starter. Component function: This component is the primary power source for the magneto ignition. Under the high vibration and stress conditions typical of off-road riding, it must reliably generate three-phase current and primarily power the following systems: Electric starter: Provides sufficient current to the starter motor and ensures continuous battery charging. Electronic fuel injection: Delivers a stable operating voltage to the ECU, fuel injectors, and various sensors (applies to models with electronic fuel injection). Ignition system: Supplies power to the ignition coil. Lighting: Supplies power to the headlight and taillight (if equipped or activated). Targeted symptoms: This product helps resolve common electrical problems on this year's WR450F models: difficulty or failure to start with electric power, rapid battery drain, sudden engine stalling or loss of power while riding (due to insufficient power), dim or non-functional headlights, electronic fuel injection malfunction indicator light illumination, and detection of low or unstable charging voltage.
