RMSTATOR Red Aluminium Mosfet Regulator for Suzuki
Suzuki Boulevard C50, C90, M50, GSX-R 600 / 750 / 1000, Bandit, Hayabusa, V-Strom and more - Part RMS022-106226
A brand new RMSTATOR red machined aluminium MOSFET regulator, built as a heat dissipation upgrade for Suzuki charging systems rather than a like-for-like replacement. RMSTATOR quote a measured figure for the difference the billet housing makes: after ten minutes of use the aluminium heatsink runs 33 per cent cooler than a standard cast regulator housing. Since heat is what wears out the semiconductors inside a regulator, running cooler is the most direct route to a longer service life.
The unit uses MOSFET regulation technology for three-phase permanent magnet charging systems, switching surplus stator output away instead of burning it off inside the casing as a diode-style regulator does. Overheat protection is built in - under a sustained overload it shuts off temporarily rather than burning up. Fitting is plug-and-play: two plugs, seven pins, seven wires with 300 mm tails, a 92 mm square body and fixing holes on 75 mm centres. The opposite connector for the main harness side is supplied in the box, because corrosion in that plug is a common and easily overlooked cause of repeat charging faults.

Frequently Asked Questions
Does it need any modification to fit?
No. It is a direct replacement with plug-and-play installation - two plugs, seven wires with 300 mm tails and fixing holes on 75 mm centres. Because the part covers both cruiser and sportsbike models across a long span of years, check the number on your original regulator against the cross reference table before ordering.
What is included?
The regulator with its seven wires and two plugs, plus the opposite connector for the main harness side so the loom-side plug can be renewed at the same time.
How do I tell whether my old regulator has failed?
With the engine running the battery should see at least 14.5 V +/- 0.5 V. A reading that never rises means the unit is not charging; one that climbs above 15 V means it is no longer regulating and will overcharge the battery. On the GSX-R models a regulator that is scorching hot after a short ride, or a harness plug with browned or corroded pins, is the classic warning sign.
Why is a MOSFET unit worth fitting to these Suzukis?
The original diode-style regulator turns surplus stator output into heat inside its own body, and on a faired sportsbike there is little airflow to carry that heat away. MOSFET regulation switches the excess instead, and the machined aluminium housing sheds what heat remains far more effectively than the cast original.
