Regulators / Rectifier

Browse 500+ replacement regulator rectifiers for motorcycles, ATVs, quads, scooters and UTVs. A failing regulator rectifier is the number-one cause of charging problems — flickering lights, batteries that drain overnight or overcharge and boil, and bikes that die at idle. Every unit here is a direct-fit aftermarket replacement designed to restore stable charging voltage.

We cover Honda, Yamaha, Suzuki, Kawasaki, Polaris, Can-Am, Arctic Cat, Triumph and more — including upgraded MOSFET regulator rectifiers for sports bikes like the Honda VFR800 and CBR series, which run cooler and last longer than the original shunt-type units. Each listing shows the exact model and year fitment plus OEM part number cross-references, so you can match your original part with confidence.
