Suzuki Motor Corporation 32800-15810-RX0 Rectifier Unit

A genuine Suzuki regulator/rectifier assembly, part number 32800-15810-RX0, is the OEM Rectifier Set designed for the GSX1300BK (Hayabusa) platform. This regulator/rectifier unit is part of the motorcycle’s charging system and is used to convert the alternator’s AC output to DC to charge the battery and power the bike’s electrical loads. Suzuki lists 32800-15810-RX0 as the regulator/rectifier assembly for the GSX1300BK, with the closely related 32800-15820-RX0 used for the GSX1300R variant; these part numbers appear in Suzuki recall and parts-catalog documentation. This replacement aligns with Suzuki’s original design, offering compatible mounting points and electrical connections for proper fitment in applicable Hayabusa models from that generation. When replacing a failing regulator/rectifier, this OEM rectifier set helps maintain correct charging voltage and reliable operation of lights, ignition, and accessories on compatible GSX1300BK motorcycles.
