This is a brand new aftermarket voltage regulator rectifier built as a direct replacement for the original unit fitted to the Suzuki DR 250, DR 350 and RMX 250 between 1989 and 1999. It is a plug-and-play, direct fit part, so it mounts and connects exactly like the factory regulator with no assembly required and no wiring modifications.
The regulator rectifier is built with a higher grade of electrical components than the original, so the quality exceeds the OEM equipment it replaces. Every unit is tested before it is shipped. Please note the manufacturer's own fitment warning: this regulator fits off-road models only and it does not fit dual sport models.

Frequently Asked Questions
Does this need any modification to fit?
No. It is a direct replacement for the original unit - plug-and-play, direct fit and easy to install, with no assembly required. It uses the same single 2-pin plug as the factory regulator.
Will it fit my dual sport DR?
No. The manufacturer states clearly that this regulator fits off-road models only and does not fit dual sport models. Check the part number stamped on your original unit against 32500-14D00 before ordering.
What is included?
One brand new voltage regulator rectifier, tested before shipment. No additional hardware is listed for this part number.
How do I know the old regulator has failed?
A healthy charging system should hold at least 14.5 V +/- 0.5 V at the battery with the engine running. A battery that will not hold charge, headlights that dim or surge with engine speed, boiling or repeatedly flat batteries, or a regulator body that is scorched or has a melted connector all point to a failed unit.
