This regulator rectifier is a direct plug-and-play replacement for a wide range of Kawasaki ATV and motorcycle applications, covering the KLF220/250 Bayou, KLR650, KL600/650, ZN1200/1300 Voyager, and ZR550 Zephyr from 1985 to 2011. Higher-grade electrical components that exceed OEM specification ensure reliable charging system performance. No assembly required.
