This is a brand new aftermarket generator stator built as a direct replacement for the original charging unit fitted to the Suzuki Boulevard M109R and the VZR1800 from 2006 through to 2024. It replaces Suzuki OEM part number 32101-48G20 and is a plug-and-play, direct fit assembly, so the original mounting points, wire routing and connector position are all preserved and no modification of the loom is needed.
The stator is built on the highest grade lamination materials and wound with the highest grade copper, with insulation resistant to 200 degrees Celsius. Because a failing stator on these big cruisers is very often accompanied by a melted, corroded or otherwise defective connector on the harness side, this assembly is supplied with its own connector, a rubber grommet and an additional opposite connector for the main harness, so both halves of the joint can be renewed at the same time. The pickup coil is included with the assembly.

Frequently Asked Questions
Do I need to modify anything to fit this stator?
No. It is a plug-and-play, direct fit replacement for the original 32101-48G20 unit. The mounting holes, the wire lengths and the connector all match the factory part, so it fits the existing stator cover and plugs into the loom as it is.
What comes in the box?
The generator stator, the pickup coil, the connector, a rubber grommet, and an additional opposite connector for the main harness side. That extra connector is included because the original one is very often melted, corroded or otherwise defective by the time the stator itself gives up.
How do I know the old stator has failed?
A battery that keeps going flat, dimming lights at idle, or charging voltage that never rises above battery voltage are the common symptoms. With a multimeter you should read roughly 0.5 ohms between any two of the black alternator leads, and about 239 ohms across the blue and green pickup wires, both within plus or minus 20 per cent. Any open circuit, or continuity between a winding and the stator body, confirms a failure.
Is the pickup coil included, or do I have to reuse mine?
The pickup coil is supplied as part of this assembly, with a 240 mm lead to the grommet. You do not need to transfer the pickup from your old stator.
