Honda CB1000SP pistons may fail causing rear wheel lockup or oil leak
Honda is recalling certain 2025 CB1000SP motorcycles because improperly manufactured pistons and piston rings can lead to rod bearing failure, rear wheel lockup, or oil leaking onto the rear tire.
What this means for you
Our assessment, not the agency’s: severity 4/5 (Severe).
The hazard poses a serious risk of illness, injury, or structural failure. Stop using the product immediately and contact the manufacturer for a refund or repair.
Our severity reasoning: Rubric level 4 covers structural vehicle defects: internal engine failure can lock the rear wheel of a motorcycle, which is a loss of control rather than a degraded function.
Plain-English summary
Honda (American Honda Motor Co.) is recalling certain 2025 CB1000SP motorcycles. About 474 units are potentially affected.
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.
NHTSA states that rear wheel lockup increases the risk of a crash or injury, and that engine oil leaking onto hot exhaust components increases the risk of a fire.
Dealers will inspect and repair the engine assembly as necessary, free of charge. Interim letters notifying owners of the safety risk were mailed on February 9, 2026, with additional letters once the remedy is available. Owners may contact the NHTSA Vehicle Safety Hotline at 1-888-327-4236.
