Honda CBR600RR recall: The cylinder head may have been improperly manufactured

Recall published 10 months ago

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 hazard: Tyre or wheel defect

The campaign concerns a wheel or tyre that may fail in service, which is why checking the code on the sidewall is the first job.

What the notice says: 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.

Why it matters: A tyre or wheel may fail in service. A sudden tread separation or wheel failure at speed is difficult for any driver to control, whatever their experience.

What to do about Tyres

Honda — The campaign concerns a wheel or tyre that may fail in service, which is why checking the code on the sidewall is the first job.

  1. Check the DOT code on the tyre sidewall or the part number on the wheel against the identifiers listed in the notice.
  2. Check your own VIN at nhtsa.gov/recalls before you do anything else. A campaign covers a build range, not every car of that model year, and the VIN lookup is the only thing that confirms yours is included.
  3. Call any franchised dealer for the brand, give them the campaign number from this page, and ask them to confirm parts are in stock before you book — part supply, not labour, is what delays a fresh recall.
  4. Do not keep running on an affected tyre while you wait for stock — ask about a temporary replacement, which is normally provided free.

Getting the repair booked and paid for

The money side of a vehicle recall is simple. The scheduling side is where people lose weeks.

  • Ask whether the parts are physically in stock before you accept a date. A booking without parts is a wasted morning.
  • Where the manufacturer has issued an interim measure — park outside, do not drive, a software limiter — follow it until the full remedy is done.
  • Reimbursement claims for earlier out-of-pocket repairs go to the manufacturer, not the dealer, and need the original itemised invoice.
  • If you get nowhere, file at nhtsa.gov. Complaints tied to an open campaign number carry weight.

Remedy named in the notice: 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.
