This is a Buell Ulysses XB12XT Heavy Duty MOSFET Regulator Rectifier with an impressive 50 amp Capacity! This part should work great if you run other electronics on your motorcycle. This 50 amp regulator rectifier is able to handle much more current than the OEM regulator rectifier. If you have replaced your regulator rectifier more than once on you motorcycle, then you might want to try this Ultra Heavy Duty model. This 50 AMP Regulator Rectifier is larger than the stock part, and will have to be mounted in a different location.
This unit replaces Buell OEs Y030.02A8 and Y1302.02A8, which are known to not be able to handle the load of this motorcycle's charging system.
