Machined Aluminium Mosfet Regulator Rectifier
Triumph 600, 650, 955, 1050 (1994-2018) · Ducati 749, 848, 999, 1198 (2003-2015)
This is a red machined aluminium MOSFET voltage regulator rectifier, part number RMS022-106230, designed for powersports charging systems and supplied for Triumph 600, 650, 955 and 1050 models from 1994 to 2018 and Ducati 749, 848, 999 and 1198 models from 2003 to 2015. The regulator rectifier converts the alternating current produced by the stator into direct current and holds the system voltage steady, so it is the component that decides whether the battery is charged properly or slowly cooked.
Heat is what kills regulators, and the billet aluminium heatsink on this unit runs 33 percent cooler than a standard cast regulator housing after ten minutes of use. MOSFET switching, built-in overheat protection and a 50 A / 500 W maximum charging current give it the headroom that the original cast units lack. Installation is plug-and-play, the body measures 94 mm long by 90 mm wide by 30 mm high with fixing holes 79 mm apart centre to centre, and the opposite connector for the main harness side is included in the box.

Frequently Asked Questions
Does fitting it require any modification?
No. Installation is plug-and-play, and the opposite connector for the main harness side is supplied so the loom can be joined without cutting into the original wiring.
What is included?
One machined aluminium MOSFET regulator rectifier plus the opposite connector for the main harness side.
How do I know my old regulator has failed?
Typical signs are a battery that keeps going flat, charging voltage that sits below the 14.5 V this unit is rated to deliver, boiling or bulging batteries from overcharging, and a regulator body that is discoloured or too hot to touch after a short ride.
Why choose a MOSFET regulator over the original cast unit?
MOSFET switching wastes less energy as heat, and the machined billet aluminium heatsink here runs 33 percent cooler than a standard cast regulator housing after ten minutes of use. Overheat protection and a 50 A / 500 W maximum charging current give the unit more margin under sustained load.
