Most of the orginal Regulator Rectifiers were manfacturered by Shindengen ( A Japanese OEM part maker) This company makes regulator rectifiers Honda, Kawasaki, Suzuki, Can-AM, and Yamaha. It is likely you will see an SH-XXX <- number on the part ( e.g SH521-12). We have itendified many of these "Sh numbers" and put these numbers into our product descriptions.
