Honda CB1000SP recall: The pistons and piston rings may have been improperly manufactured

Recall published 10 months ago

The pistons and piston rings 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

This recall covers tyres or wheels, where the identifying code is moulded into the product itself rather than printed on a label.

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 — This recall covers tyres or wheels, where the identifying code is moulded into the product itself rather than printed on a label.

  1. Check the DOT code on the tyre sidewall or the part number on the wheel against the identifiers listed in the notice.
  2. Have the spare checked too; it is frequently from the same production batch and is just as frequently forgotten.
  3. Keep the repair order the dealer hands you. It is your proof the campaign was closed out, and it matters at resale.
  4. 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.

Costs, reimbursement and your rights

The repair itself is free. What people most often miss is that money already spent can frequently be claimed back.

  • If you paid for the same repair out of pocket before the recall was announced, ask the manufacturer for reimbursement. Carmakers must run a reimbursement plan for pre-notification repairs; you will need the original invoice.
  • An unrepaired open recall can affect a sale or trade-in. Closing it out costs nothing and protects the value of the vehicle.
  • Towing is normally covered where the vehicle is unsafe to drive, and loaner cars or rental reimbursement are often available on long parts delays. Neither is usually offered unless you ask.
  • A dealer may not charge a diagnostic, inspection or shop-supplies fee for recall work. If one appears on the estimate, query it before you sign.

Remedy named in the notice: Dealers will inspect and repair the engine assembly as necessary, free of charge. Interim letters notifying owners of the safety risk were mailed February 9, 2026. Additional letters will be sent once the remedy is available, anticipated December 30, 2026. Owners may contact Honda's customer service at 1-866-784-1870. Honda's number for this recall is KT6. Vehicle Identification Numbers (VINs) involved in this recall will be searchable on NHTSA.gov beginning January 7, 2026.
