Vehicle report
Technical service bulletins are instructions a manufacturer sent its dealers about a known fault. They are not recalls and the work is usually not free, but they are the clearest signal of a problem the manufacturer already knows about.
MC25-12
2024 ~ 2025 ZX636J/K OIL & FILTER CHANGE (Factory Authorized Repair). This bulletin only applies to motorcycles that were eligible for recall MC25-08 and not repaired. Owners that did not have recall repairs completed under recall MC25-08 require an oil change under recall MC25-11.
Complaint counts are reports filed with NHTSA, not failure rates. A common model collects more of them than a rare one that breaks more often.
