For Single Phase, Permanent Magnet Charging Systems Only. This includes many Vintage British Twins, and small to medium displacement bikes like Vintage Honda Twins CB350, CB450, CB500T, etc.) 

The Single-Phase Reg/Rec from Rick's Motorsports Electrics is a universal, dead simple solution for upgrading one of the most basic of all the charging systems, the single phase permanent magnet alternator. This unit is a solid state combination regulator-rectifier that has a max charge output of 14.2v, optimized to work with Lithium batteries, however, it is still 100% compatible with Lead Acid chemistry like AGM and Gel Cell batteries.

Think of it as a modern replacement for the classic Tympanium or the separate Regulator and Rectifier modules on older bikes.
