Related Charging System Part
If your Suzuki Hayabusa GSX1300R battery is not charging or the voltage output is unstable, the problem may come from the regulator rectifier, stator, battery, wiring, or connectors. When replacing the rectifier, it is recommended to test the stator output as well.
If your stator is damaged or producing weak output, consider our Suzuki Hayabusa GSX1300R Magneto Stator, designed to replace OEM 32101-24F00 / 32101-24F10.
Package Includes
1 × Voltage Regulator Rectifier
Fitment Note
Please confirm your OEM part number, connector style, mounting layout, and original part appearance before ordering.
If you are unsure about compatibility, contact us with your model, year, OEM number, connector photos, and original part photos before purchase.
Installation Note
Professional installation is recommended.
Before installation, inspect related components such as the battery, stator, wiring harness, connectors, and charging system to avoid repeat failure caused by another faulty part.
Why Choose This Replacement

Fitment FAQ
Will this part fit my specific model and year?
This voltage regulator rectifier is intended for Engine / HP / CC. Listed year information includes 1999–2007, 2001–2005, 1998–2005, 2001–2004, 1999. It is best matched to original part number(s) 32800-33E21, 32101-24F00, 32101-24F10. Key physical/spec details from the product data include 1 × Voltage Regulator Rectifier, 1300cc, 600cc. Use the compatibility table and product photos together before ordering.
Do I need to match the OEM part number?
Yes. Match your original part number to 32800-33E21, 32101-24F00, 32101-24F10 before purchase. For this voltage regulator rectifier, also compare the OEM number, plug shape, pin count, mounting-hole distance, heat-sink style, and AC/DC charging-system type. This is especially important for Suzuki GSX1300R/R600/R750/R1000 models because similar model names can use different parts by year or trim.
What models or situations does this part not fit?
Do not order this voltage regulator rectifier for machines outside the listed compatibility, or for units with different pin counts, plug shapes, AC/DC system types, or mounting-hole spacing. If your original part number does not cross-reference with 32800-33E21, 32101-24F00, 32101-24F10, treat the fitment as unconfirmed. Model years outside 1999–2007, 2001–2005, 1998–2005, 2001–2004, 1999 should be verified separately. Do not rely only on the model name or engine size.
What should I check before ordering?
Before ordering, compare your original part with the photos and check the OEM number, plug shape, pin count, mounting-hole distance, heat-sink style, and AC/DC charging-system type. Confirm OEM/cross-reference number(s): 32800-33E21, 32101-24F00, 32101-24F10. Recheck listed specs such as 1 × Voltage Regulator Rectifier, 1300cc, 600cc. If any connector, mounting point, size, or year detail is different, confirm fitment before installation.
