This 3-in-1 kit directly replaces weak OEM charging components on Yamaha YFZ 450 R/X (2009–2024). It fixes common issues: stator burnout, flywheel magnet loss, regulator overheating, and battery undercharging. The high-output stator delivers 300W (vs OEM 208W) for reliable power at idle and high RPM. The reinforced flywheel eliminates crankshaft vibration and magnet separation risks. The MOSFET regulator runs cooler and maintains a stable 14.1V charge, extending battery life. All parts are pre-tested for plug-and-play installation, saving time and repair costs. Ideal for racing, heavy use, or OEM upgrade.
