Re-Designed and Improved heavy duty Ducati 900 Superlight Regulator Rectifier has a higher power handling ability than the original OEM part. This regulator rectifier runs at a lower temperature than the OE regulator rectifier, which will give more controlled voltage output at all RPMs! Many older Ducati's have poor wire connections in the wiring harness. This particular regulator rectifier is designed to have output wires that are connected directly to the battery terminals. For a plug in replacement unit just like the original regulator check out the R515 regulator rectifier, it is just like this one but you can plug it in the OE wiring harness. This regulator rectifier one has a 20 amp fuse which allows you to hook it up directly to the battery allowing maximum connectivity. Will work for the following models: 1992-1995 Ducati 900 Superlight 1996 Ducati 900SL Superlight * If you would like the plug and play connection type see part # R515
