Product Overview
Replace a damaged, overheated, or unstable voltage regulator rectifier with this replacement unit, designed for select Honda CBR600RR, CBR929RR / CBR900RR, and CB900F motorcycle applications using OEM reference number 31600-MEE-872.
The voltage regulator rectifier is an important part of the motorcycle charging system. It helps regulate and stabilize charging output before power reaches the battery and electrical components. A faulty regulator rectifier may cause weak charging, battery overcharging, repeated battery failure, dim lights, blown bulbs, unstable voltage, melted connectors, or electrical system problems.
This replacement regulator rectifier measures approximately 92.70mm long, 83.82mm wide, and has a 72.27mm mounting hole spacing. Please compare your original regulator’s OEM number, plug shape, wire layout, mounting hole spacing, body size, and charging system design before ordering.

Fitment FAQ
Will this part fit my specific model and year?
This regulator rectifier is designed for select Honda CBR600RR 2003–2006, CBR929RR / CBR900RR 2000–2001, and CB900F 2002–2007 applications using OEM reference number 31600-MEE-872 or matching related references. Please compare your original part number, plug shape, wire layout, body size, and mounting hole spacing before ordering.
Do I need to match the OEM part number?
Yes, matching the OEM or reference number is strongly recommended. This regulator rectifier replaces Honda 31600-MEE-872 and may cross-reference with 31600-MEE-003 and 31600-MCJ-641 on related applications. However, OEM number alone is not enough. Please also confirm the connector shape, wiring layout, mounting hole spacing, body size, and charging system type.
What models or situations does this part not fit?
This part does not fit Honda CBR600RR, CBR929RR, CBR900RR, CB900F, CBR1000RR, CBR954RR, VFR, Shadow, Rebel, or other Honda motorcycles that use a different regulator body, different connector shape, different wiring layout, different mounting distance, or different charging system design. It is also not a replacement for the stator, battery, starter relay, fuse box, ignition coil, CDI / ECU, or complete wiring harness.
What should I check before ordering?
Before ordering, please check your motorcycle make, model, year, trim version, original regulator part number, plug shape, wire layout, mounting hole spacing, body length, width, thickness, and charging system type. For best fitment, compare the product photos and specifications with your original regulator rectifier before purchase.
