The defect
Honda (American Honda Motor Co.) is recalling certain 2024-2026 CBR600RR motorcycles. The cylinder head may have been improperly manufactured, which can lead to rod bearing failure, possibly resulting in rear wheel lock up or oil leaking onto the rear tire.
The risk
Rear wheel lockup increases the risk of a crash or injury. Engine oil that leaks onto hot exhaust components increases the risk of a fire.
The remedy
Dealers will replace the engine assembly, free of charge. Interim letters notifying owners of the safety risk were mailed February 9, 2026. A second letter will be sent once the remedy is available, anticipated October 31, 2026. Owners may contact Honda's customer service at 1-866-784-1870. Honda's numbers for this recall are KT5 and KU3. Vehicle Identification Numbers (VINs) involved in this recall will be searchable on NHTSA.gov beginning January 7, 2026.

What this page is, and what to do next
A recall is not an opinion. It is a Part 573 report a manufacturer is required by federal law to file once it decides a defect poses an unreasonable risk to safety, and it commits them to repairing the vehicle at no cost to the owner. The three passages above are the manufacturer’s own wording as published by NHTSA.
This page describes the campaign. It cannot tell you whether one particular car has already been through the shop — that is tracked by VIN, and only the manufacturer knows it. Check yours at nhtsa.gov/recalls or with a franchised dealer, quoting campaign number 25V891000.
