This Regulator/Rectifier has been upgraded from previous offerings and from the OEM design. The new version now offers 50A capacity, and a large casting/better cooling design. This R/R features MOSFET technology like the popular FHA012AA from the Yamaha R1. It is made by Ricks Motorsport Electrics, arguably the best Honda Aftermarket supplier I have found. The unit carries a 1 year warranty from time of order.
