Suzuki has issued recall campaign 3A04 for 2022–2024 Hayabusa models to replace front brake master cylinder components that can swell and impair braking, potentially increasing stopping distance and crash risk.
Owners will receive a free repair consisting of a new master cylinder body and updated reservoir cap diaphragm; this campaign supersedes prior actions and should be performed even if earlier recall 2A99 was completed.
What’s being recalled
Suzuki Motor Corporation determined that an additive in the front brake reservoir cap diaphragm can contaminate brake fluid and swell rubber parts inside the master cylinder on certain GSX1300R Hayabusa units from model years 2022–2024 (GSX1300RM2–M4).
The swelling can affect brake fluid pressure and require greater-than-normal lever travel on subsequent applications, which can extend stopping distances and raise crash risk. NHTSA lists this as campaign 24V769000, covering an estimated 6,338 units in the U.S. market under Suzuki’s internal campaign number 3A04.
Symptoms and safety risk
When affected, the front brake lever may feel “spongy” or exhibit excessive travel, especially on a subsequent squeeze after initial application due to compromised pressure build-up. Riders may experience longer stopping distances, which is considered a safety defect and prompted stop-delivery instructions to dealers until the recall service is completed on affected motorcycles.
The official remedy
Dealers will replace the front brake master cylinder body and the reservoir cap diaphragm with updated parts that do not cause rubber swelling, free of charge to owners. The repair typically takes about one hour, though dealers may request additional time for processing and can coordinate parts ordering ahead of the visit to minimize downtime.
Suzuki initiated owner notifications around late October 2024, sometimes the dealer will offer an ECSTAR oil change and 30‑point check offered when the bike is in for the recall at participating dealers. I’ve even heard of them towing it in for some riders as well.
Relationship to earlier recalls
Campaign 3A04 expands and replaces prior actions, explicitly superseding recall 2A99 (and NHTSA 23V‑088) regarding the front brake master cylinder on 2022 models. Even if a Hayabusa already had 2A99 performed, Suzuki requires completion of 3A04 because the updated parts and instructions address the reservoir cap diaphragm contamination pathway. Dealers have been instructed on handling any unused 2A99 parts kits and to ensure only the 3A04 remedy is applied going forward.
What owners should do
Schedule an appointment with an authorized Suzuki dealer and reference recall 3A04 (NHTSA 24V769000) so parts can be ordered in advance for a one‑visit repair at no cost for parts or labor. Until the remedy is performed, I personally wouldn’t ride it. For questions, contact Suzuki Customer Service or consult the NHTSA recall lookup using the motorcycle’s VIN to confirm eligibility and status.
