Remanufactured Suzuki GT380 | GT550 | GT750 Voltage Regulator MOSFET

Original Regulator cleaned, repainted and plated then fitted with Mosfet Voltage Regulator Conversion

This modern MOSFET regulator transforms the original mechanical unit (Suzuki 32500-31010) used on the GT380, GT550, and GT750 into a reliable, solid-state upgrade inside the original case.

We’ve engineered the electronics to fit inside the original regulator housing, preserving the authentic look and maintaining the bike’s collector value. From the outside, it looks virtually identical to the factory part—while inside, modern components deliver precise voltage control, improved charging performance, and long-term reliability.

Note,  this batch has been graded as B-grade due to visible surface imperfections—light pitting or marks—left behind after corrosion removal and replating. These blemishes are purely cosmetic and do not affect the performance or reliability of the unit in any way.

• Original Suzuki 32500-31010 part which has been restored & modified with a MOSFET regulator circuit.

• Fits GT380, GT550 & GT750

• Maintains original appearance and mounting points

• Stable voltage regulation with no moving parts

• No adjustment or maintenance required

An invisible upgrade that keeps your bike original—where it matters most.
