Got electrical issues with your Yamaha 450? This Topteng kit might be just what you need. It's a bundle that includes the Stator Coil, the Voltage Regulator/Rectifier, AND the Generator Cover Gasket – all the bits you usually need to replace together.
It's made to fit specific models: the Yamaha WR450F from 2016 to 2018, and the YZ450 & YZ450FX from the same years. Super important – double-check your bike's exact year and model before you click buy! The part numbers it replaces are: Stator Assy 2GB-81410-01, Regulator 2GB-81960-00, and Gasket 1SL-15451-00.
They say it's built with high-grade magnetically conductive material to cut down on power loss, and the copper wiring is done by computer for consistent quality. The electrical components are supposedly a higher grade than stock, aiming for better reliability and a longer life. The wires have good insulation for heat and abrasion resistance.
The regulator is made with good conductive materials and is meant to have improved heat sinking and charging ability. It's a direct, plug-and-play replacement – should bolt right up like your original part. (Just a heads up, instructions aren't included, so you'll need to know your way around your bike or have a manual).
If your charging system is acting up, this all-in-one kit can save you some hassle. Brand new aftermarket parts.
